How To Check & Compare UK Mobile Coverage: Networks & MVNOs

February 3rd, 2015

Coverage should be your top consideration when choosing a new mobile network. Find out how to choose the mobile phone network offering the best coverage in your area.

Mobile phone coverage is provided by mastsIf you’re choosing a new mobile phone network, the level and the quality of coverage should be the most important thing to consider. You’ll need to have good mobile coverage in order to get a satisfactory experience when using your phone. Poor coverage can lead to missed phone calls, text messages being delayed and web pages failing to load. It can also affect your mobile phone’s battery life (poor mobile coverage will very quickly drain the battery life from your smartphone).

With the UK having more than 20 mobile networks, it seems rather daunting to choose the network with the best coverage. In this guide, we outline the basics of how to check and how to compare mobile coverage in the UK. We’ll discuss the UK’s system of virtual network operators: understanding this will save you vast amounts of time when comparing the coverage across networks. We’ll also discuss how to assess the quality of coverage offered on each network: the key things you should be looking out for and the factors that’ll make a difference to your mobile phone experience.

Check & Compare Mobile Coverage

UK Mobile Coverage is provided by four providersIn the UK, only four companies hold a license to build their own mobile network. The four licensed companies are EE, O2, Three and Vodafone. Each of the companies has licensed some spectrum from the Government and has built their own network of mobile phone masts to cover the UK. The four companies maintain their own infrastructure and also sell mobile services directly to the consumer.

In addition to the four network providers, there are also a number of companies that re-sell mobile services. They lease spare capacity from one of the network providers and sell a mobile phone service under their own brand. Within the mobile industry, these companies are known as a “mobile virtual network operator” (or MVNO for short). Each MVNO has the power to set their own prices: hence they might charge less for calling and texting compared to the companies that maintain their own network.

The mobile signal you receive from a MVNO is actually provided by one of the four companies that maintain mobile infrastructure. For instance, giffgaff uses the O2 network whereas Virgin Mobile uses the EE network. Although you receive a service branded as giffgaff or Virgin Mobile, the actual underlying coverage comes from O2-owned or EE-owned phone masts.

It’s important to know the company that provides the signal for your network. This will allow you to use the relevant online coverage checker (an online coverage map showing the services and signal available in your area). MVNOs will give identical levels of coverage to the background network provider.

Table: UK Mobile Networks & Actual Network Providers

The table below provides a list of UK mobile networks. For each network, we’ve shown the actual network provider (this is the company that provides the underlying mobile signal). We’ve also shown the types of coverage available on each network (read on to find out more about the different types of coverage). For each network, we’ve also provided a link where you’re able to access the relevant online coverage map.

* At present, TalkTalk Mobile uses Vodafone as their network coverage provider. In November 2014, TalkTalk announced plans to change their network coverage provider to O2. No exact date has been given for the move to O2.

The mobile networks highlighted in bold maintain their own network infrastructure. Mobile networks that aren’t in bold are considered to be MVNOs. MVNOs lease their capacity from the network provider listed in the table.

How To Assess Mobile Coverage

The first step in assessing mobile coverage is to use the online coverage map relevant to your network. In the table above, click the relevant link to access the coverage map for the network you’re planning to join. You’ll normally be able to enter your postcode: this will take you directly to where you live. It’s also worth checking the places where you regularly spend time (e.g. your school, university or workplace). You’ll want to have reliable coverage at all of the places where you regularly spend time.

When checking the online coverage maps, there are two key things you should be looking for. The first is indoor coverage: being able to use your phone when inside of a building. The second is the type of coverage you’re able to access: you’ll want 3G or 4G coverage for a good smartphone experience.

Indoor & Outdoor Coverage

Coverage is weaker in buildings

Mobile coverage is weakened by buildings. Look for a network with indoor mobile coverage.

If possible, choose a mobile network that offers both indoor and outdoor coverage. This is vital if you want to use your phone inside of a building (e.g. in your home or in your office). If your network provider only offers outdoor coverage, you’re likely to get a poor smartphone experience. There’s also a high likelihood that incoming phone calls could be missed.

Note: As with all types of radio-based signal, mobile phone signals can be weakened by building materials. The presence of neighbouring buildings and the materials used to construct your home can weaken the strength of your mobile phone signal. Online coverage maps will try to take this into account. A strong 5-bar signal might be said to give “indoor & outdoor coverage”. Meanwhile, a weaker 1-bar signal might be said to give outdoor coverage only.

In reality, circumstances can differ from coverage map predictions. This is particularly the case for people living in basement flats where it can sometimes be difficult to receive a signal from any of the network providers. If you live in a basement flat or struggle to get signal from any of the network providers, consider a broadband-based solution such as O2’s Tu Go, Three’s inTouch or Vodafone’s Sure Signal.

Types of Coverage: 2G, 3G & 4G

When studying an online coverage map, you’ll normally be shown the levels of 2G, 3G and 4G coverage.

Types of Coverage: 2G, 3G and 4G

2G, 3G and 4G relate to the download speeds you can obtain on your smartphone.

  • 2G is the oldest type of mobile network still in use today. It’s mainly designed for calling and texting but you’re also able to do some basic web browsing. If you’re just looking to call and text, 2G coverage should suffice for your needs. However, if you’re a smartphone owner, we would strongly recommend choosing a network with 3G or 4G coverage.
  • 3G (recommended minimum) is the basic level of coverage expected on mobile networks today. It’s designed for smartphone users: you can browse the web and you can use almost any app. You can also call and text as you can on 2G. A good 3G connection should be fast enough for almost any activity on your smartphone. This includes listening to online radio, video calling with Skype or FaceTime and television streaming through the BBC iPlayer application.
  • 4G is the next-generation of mobile phone network. It provides faster downloads and a better online experience compared to 3G. The table above shows a list of the networks currently offering 4G mobile coverage. Please be aware: you might need a special 4G-enabled tariff before you’re able to access the 4G coverage (a premium will sometimes be charged for this).

Whenever possible, you should choose a mobile network offering 3G or 4G connectivity.

Real World Experimentation

Finally, it’s worth noting that the data shown in online coverage maps is based upon computer predictions. It gives your network provider’s expectation of coverage based on geography and where their masts are located. As discussed earlier in this article, the actual level of coverage you’re able to receive may depend on other factors (e.g. the materials used to construct your home and the presence of other nearby buildings).

SIM Card

You can order a free Pay As You Go SIM card to test the level of coverage.

Before signing up to a 24-month contract, you may wish to carry out a real world experiment. For instance, ask your family members about their experience of a certain network provider. They don’t need to be a customer of the exact network you’re planning to join: they simply need to use a mobile network that shares the same underlying coverage provider. Is their mobile service reliable at home? Do they ever experience problems with coverage?

A further way to test this is to order a free Pay As You Go SIM card from the network you’d like to join. You can put the SIM card into any unlocked smartphone: check to see whether the coverage is reliable. How many bars of signal are you able to get on the phone? Android users can get a numerical value for the strength of the network coverage: on your smartphone, navigate to Settings > More > About device > Status and read off the ‘Signal strength’ value. A smaller dBm equates to better signal (e.g. -80 dBm is much better than -90 dBm). You can test the level of coverage once for each network provider.

Overview of Mobile Coverage in the UK

The UK has four network providers: EE, O2, Three and Vodafone. Please refer to the detailed coverage maps (linked below) for an overview of the service available where you live.


EE (99% coverage)

EE is the UK’s largest mobile network provider. As well as providing services under their own brand, they provide the underlying network for ASDA Mobile, BT Mobile, Co-operative Mobile, Delight Mobile, Family Mobile, LIFE Mobile, Orange, The People’s Operator, T-Mobile, Vectone Mobile and Virgin Mobile.

At present, 4G is only available on the EE brand. As of January 2015, EE has 80% population coverage for 4G. They’re aiming to have 98% 4G population coverage by the end of 2015.

About MVNOs

O2's MVNOs: giffgaff, Tesco Mobile and Lycamobile

O2 uses MVNOs to target different parts of the market.

Mobile virtual network operators (MVNOs) lease spare capacity from a mobile network provider. The UK has four network providers: EE, O2, Three and Vodafone. The underlying network provider manages all of the fixed network infrastructure (e.g. the required licenses, the mobile masts and the network of backhaul connections). The virtual network operator simply provides services such as billing and customer support.

In some cases, the virtual network operator is owned or is partly-owned by the underlying network provider. This can be a hugely effective way for companies to target different groups of customers. For instance, O2 owns 50% of Tesco Mobile and 100% of giffgaff. Compared to the main O2 brand, Tesco and giffgaff target more price-conscious consumers. O2 is therefore able to attract price-conscious consumers on their MVNO subsidiaries without cannibalising the revenues on their premium core brand.

Savvy consumers can often save money by switching to a low-cost MVNO. They’ll receive the same underlying service at a reduced monthly cost.

Historical Information

The information in the table above shows the current line-up of UK virtual network operators. In the past few years, certain MVNOs have changed the network they lease spare capacity from. This has changed the level of coverage they can offer.

  • ASDA Mobile. In October 2013, ASDA Mobile switched to using the EE network. Prior to this, ASDA operated their mobile service on the Vodafone network.
  • BT Mobile. The BT Mobile service launched to consumers using EE’s mobile network in March 2015. Prior to this, BT had a business-only mobile service which operated on Vodafone until summer 2014.
  • Lycamobile. In 2010, Lycamobile switched to using the O2 network. Prior to this, Lycamobile used the Orange network.
  • Orange & T-Mobile. In October 2011, Orange and T-Mobile combined their network operations. They created a single combined network under the EE brand. The combined 3G networks of Orange and T-Mobile have now become the 3G network of EE. In addition, EE has launched a 4G network but this isn’t available to customers on Orange or T-Mobile. As of February 2015, it’s no longer possible to take a new plan on Orange or T-Mobile.
  • OVIVO Mobile. OVIVO Mobile previously used coverage from Vodafone. The service was closed on March 19th 2014.
  • TalkTalk. In November 2014, TalkTalk signed an agreement to change their network coverage provider from Vodafone to O2. At present, customers are still yet to be switched to using coverage from O2. Hence, customers on TalkTalk currently continue to receive coverage from the Vodafone network. There is no timeframe at present for when customers will be moved over to O2’s network.
  • Sky. In 2016, Sky is due to launch a MVNO using coverage from O2.

    Could any one give me the unlock code from ee to giffgaff as I’ve got Samsung galaxy s5 mini and no longer want to be with ee. I want to go to giffgaff but now they’re telling me I have to pay to change. not good. another thing, I brought the phone now they want to charge me to go to giffgaff. any one with unlock pls help – it’s a s4 mini (GT-I9150). thanks

      Hi Ash,
      Thanks for your comment. Unfortunately, EE charges £20.42 if you want to unlock a phone from their network (see this article for more information). Unfortunately, there aren’t many ways you’re able to get around this (unless you’re able to find a working unlock method that’s free).
      With regards to a PAC Code for moving your number from EE to giffgaff, it should always be free to receive this code (it’s your legal entitlement and EE must provide it free of charge within two hours of your request).

    Hi, I am a volunteer for a village ‘good neighbour’ network. We have 6 volunteers who share a basic 2G phone on EE network to take calls from villagers wanting transport to hospital etc. We are in a very poor network coverage area (coverage worsened in last few months). We cannot use a signal box as that would mean moving it to a different house each week. We have lobbied network providers, local MP, council etc. re getting improved coverage. In long term there’s possibility of mast on new community centre. Any advice on how we could improve things on short term basis? Would a 4G phone give us any advantages – e.g. transferring calls to a landline?
    We would appreciate any advice you may be able to offer

      Ken replied:

      Hi Jill,
      I’m afraid I can’t give you very much advice regarding the situation beyond trying to get a femtocell e.g. a Vodafone Rural Open Signal.
      I would say that 4G probably isn’t useful for calling at the moment: today’s 4G networks don’t actually support voice calling (they use a technology called CSFB whereby your phone actually falls back to a 3G network in order to make a phone call). Hence, it’s probably best to focus on getting 3G coverage rather than 4G (at least for the time being).
      Wishing you all the best of luck with the campaign,

    Hi Ken, after being given the “truth about supermarkets mobile providers/coverage” by 1 of the big 4 mobile providers keen on getting my business, but not keen on me going elsewhere, here i found the truth, the whole truth and nothing but the truth!!

    I can now get a good deal at less cost & with more minutes/texts & data per month.
    So glad i found this site before being pressurized in to a 12 month contract!

  4. Adam Garfunkel said:

    Hi there. I am a Vodafone customer (and pay for my wife and eldest daughter’s phones through Vodafone). I have just been told by a Vodafone call-centre salesperson that if I go with buy the phone and the Vodafone contract through Carphone Warehouse then as Carphone Warehouse ‘only rents’ our masts, the signal will be weaker. I said I thought that sounded like bullshit. She declined to comment and said that she could not discount iPhone 6 prices. Is this ‘weaker signal’ because of renting correct?

    1. Ken Lo
      Ken replied:

      Hi Adam,
      Thanks for your comment and a very Merry Christmas! It does sound as if the call centre staff are giving you incorrect info:

      • You’ll always get the same service & coverage on a Vodafone-branded contract regardless of whether you signed up directly or via another company (e.g. the Carphone Warehouse). The signal strength will be exactly the same.
      • If you’re signing up for Talkmobile (the Carphone Warehouse MVNO which uses Vodafone’s network) the story might be slightly different. The signal strength and coverage will still be the same as Talkmobile uses Vodafone’s masts and signal. The service quality could theoretically be different (i.e. if Vodafone decides to prioritise their own customers when a mast becomes busy) but there isn’t any concrete information about what actually happens in real-world usage.

      Anyhow, it sounds to me as if the first is applicable to your situation so you can safely ignore what the call centre have told you!

      1. Adam Garfunkel replied:

        Thank you Ken. That is the way I was thinking. It is very poor that Vodafone get their staff to say that, don’t you think. More than ‘very poor’, it’s downright misleading and they shouldn’t do it. Don’t you agree?

        1. Ken Lo
          Ken replied:

          Hi Adam,
          Definitely agreed that they shouldn’t be saying this – probably a combination of poor staff training and them trying to pressure sell you a contract over the phone. Anyhow, you can rest assured you’re getting the same Vodafone service even when buying the contract elsewhere!

  5. Austin said:

    Hi Ken,
    Can you give me some advise, I would like to get a smart phone from TalkTalk who use Vodafone.
    I need the phone for London and Eastbourne, I know vodafone are OK in London but have heard their reception is poor indoors in Eastbourne, have you any info on this?
    I have been told that O2 would be better, what do you think?
    Thanks Austin.

    1. Ken Lo
      Ken replied:

      Hi Austin,
      Thanks for your comment. I’m afraid I can’t say anything about the coverage in Eastbourne (the people living locally would probably be the best ones to ask). In the first instance, I would definitely use Talkmobile’s online coverage checker. This will tell you whether indoor/outdoor coverage should theoretically be available at home, work, etc.
      In reality, your actual coverage may differ from this map (e.g. due to buildings, trees, obstructions, etc). For this reason, it’s always a good idea to first try the signal out directly in your phone. You can order a free SIM card from the network you’d like to trial (I’d probably go for Vodafone Pay As You Go in this case). Stick the free SIM in your existing unlocked smartphone and count the number of bars you get on the network. If the coverage looks OK then you should be good to sign up on Talkmobile!

  6. Dave La said:

    Thanks for some really useful information and comparisons especially on pay-as-you-go which well-known price comparison web sites don’t seem to cover.

    I think it is worth emphasising that impressive network coverage figures like 98% and 99% are percentage of the population, not percentage of the land area which is very different, so it is worth checking the coverage maps.

    A network that only supports 3G/4G may be OK in towns and cities but if like me you like to visit rural areas at weekends or on holiday then you will find substantial gaps in coverage for 3G/4G only networks. In that case, you will probably want to choose a network that also provides 2G as a backup in areas with no 3G coverage.

    As you can see from the table above, there is one network that doesn’t provide any 2G service so that would be one to avoid if you are likely to venture outside the more densely populated areas.

    1. Martha replied:

      3 does actually have some 2G coverage via a roaming agreement with EE.

      It has been turned off in areas of 3G/4G coverage and is limited to voice/text but works seamlessly from a customer’s point of view.

      1. Ken Lo
        Ken replied:

        Hi Martha,
        Thanks for the heads up on this! As you say, Three used to have a 2G roaming agreement with Orange. They began turning this off in 2011. I’m not sure how much 2G coverage is still available on Three but I’m willing to assume incredibly little. Anyone trying to use a 2G-only handset on Three will probably find their phone unable to pick up a signal.

  7. Andy D said:

    I spoke with vodafone as my contract is up and I am moving to Phone Coop which uses EE

    Before giving me my PAC code, the salesman told me that the virtual networks typically only have access to 25 %, or maybe he meant 25 % of the capacity.

    What do you make of this? Is my coverage likely to be that poor? Or is this misleading sales patter?

    1. Ken Lo
      Ken replied:

      Hi Andy,
      Thanks for your comment. You raise a really good point – virtual network operators such as the Co-Op mobile will lease their capacity from one of the network providers (EE in this case). There has been some talk about variable service quality – for instance see the comments here and here. In terms of what the salesman has told you, it’s highly likely the statistic was made up. I’ve not yet seen any concrete figures about how much priority is actually assigned to each virtual network operator (I suspect this will differ depending on the network and will only be specified in the confidential agreement between the virtual network and the underlying network provider). My feeling is it’s probably nothing to worry about and the suggestion of 25% capacity is probably a lot of nonsense.
      Hope this helps!

      1. Martha replied:

        MVNOs do get lower priority on the network than the MNOs

        E.G. O2s Hierarchy

        1st priority are O2 Business and Contract.
        2nd priority are O2 Prepay and Tesco Mobile.
        3rd priority are Giff Gaff, MVNOs and international roamers.

        It’s obviously more noticeable in congested areas and in the lower capacity bands such as 800/900 MHz

        1. Ken Lo
          Ken replied:

          Hi Martha,
          Thanks for your comment. I’ve read rumours online about this type of prioritisation but never seen anything confirmed (either in terms on a detailed independent study or an official statement from O2). Do you have any resources to this effect? I’d really love to see a detailed study (this is something the guys at OpenSignal or RootMetrics should definitely look into!) so I could update the advice given in this article.

    Hi is anyone else experiencing the Three sim activation failure syndrome, their stock answer from customer services and technical departments is “you have to wait another 24 hours” 4 days now met 18 other customers in their shop today according to their staff over 7,000 customers are affected and the issue may take weeks to rectify, you can not even move your number or cancel your contract as when you ring the cancellation line you are let on hold tried 4 times each time left for up to an hour and no answer, how can such a majo failure go unpublised? Ironicall Three have illuminated displays in their shops rubbishing the other providers bad customer relations as reasons why peole moved over to Three yet they themselves are selling phones with sim cards they know they can not activate pot calling kettle springs to mind.

    just in case antone is having a problem try emailing or ringing 01628 765000 and asking for either Mr. Cocker or Mr. Reilly

    Thanks for article. Where can I get a full list of MVNOs and providers. Shouldn’t ofcom hold an up to date list of MVNO’s and their actual network providers ?

    1. Ken Lo
      Ken replied:

      Hi Morgan,
      Thanks for your comment. I’d recommend having a look at the MVNO Dynamics site for a more comprehensive list of MVNOs. Do be aware that not all of the MVNOs are active, some are really small and many don’t sell directly to UK consumers.
      I’m sure Ofcom must also maintain a list of licensees but I’m not aware of this being available online.

    very informative for someone about to get their first smartphone

  11. Brian said:

    This is a great article but I still can’t get to the bottom of whether MVNO’s have the SAME service level as the native operators. Are they treated the same when cells are busy or do they get lower priority and suffer higher drop rates? Is there any evidence of Data throttling for the MVNOs? There is very little transparency on this as far as I can see and I haven’t found a definitive statement anywhere!

    1. Ken Lo
      Ken replied:

      Hi Brian,
      Thanks for your comment and you raise a really interesting point! The coverage should always be the same on a MVNO and the underlying network provider. This, however, doesn’t mean the level of service will always be the same (i.e. you can have the same coverage but speeds could be lower). Each MVNO can implement their own policies on the quality of service and how traffic is prioritised. As an example of this, see my article on traffic management policies and how they differ for each UK network.
      Unfortunately, there’s no public data regarding the quality of service and which customers will receive priority over others. The exact details are likely to be defined in the confidential agreements between each MVNO and the underlying network provider. It’ll also be a function of how each MVNO manages the traffic internally on their network. The answer to your question could be different depending on the MVNO (and all such evidence would be somewhat anecdotal).
      I’m aware there have been discussions regarding traffic priority on giffgaff and O2. Several people have suggested that customers on O2 often get priority (e.g. here). That said, I’m not sure if the question has ever been answered officially.

    Hi Ken, Thanks for the articles
    you made greatful contents!! amazing :)
    I have a question about MVNO
    Could we know how many MVNO in UK?
    17 operators in the table except main operators are total MVNO?

    1. Ken Lo
      Ken replied:

      Hi Joythi,
      You’re right… in the UK, all of the mobile networks are MVNOs except from EE, O2, Three and Vodafone. I’m not sure about a complete list of MVNOs… the list I’ve provided is far from comprehensive (it only covers the largest consumer MVNOs). There’s also lots of business and specialist MVNOs. The PrepaidMVNO website has a list of 90 UK MVNOs. I’m not sure how many are current – it’s possible that some of them aren’t currently trading or selling to consumers so do double-check the reliability of the list!

    I am finding that some of the Virtual operators have ‘variable’ quality in that some of them only use the spare capacity of their host network and perhaps at a lower priority :( therefore, experience a lot of ‘drop-outs’ during a calls no matter where called from.

      Hi Michael,

      Thanks! You make a really interesting point… When mobile masts are congested (i.e. when there is abnormally high traffic), I guess there would be some kind of system prioritising different types of user (e.g. business customers get priority over normal consumers). I’m not sure if there’s any specific data on how traffic is prioritised and which MVNOs receive priority over others. If any other readers have a thought on this issue or some real-world data which illustrates this happening, I’d be really interested in hearing about it!

      That said, if your local mast has plenty of spare capacity (as it should under normal circumstances) then there’s unlikely to be a difference between MVNO service quality.

        Hi Ken
        Interesting comments re MVNO receiving priority. I’m on TalkTalk mobile which piggybacks on Vodafone. I live in a small rural village and I suspected that Vodafone were squeezing TalkTalk and prioritising their own customers because my data signal has virtually disappeared over the past few months (although voice signal is good). However on checking with a different handset which uses Vodafone, and testing signal strength with the OpenSignal Android app which is installed on both the TalkTalk and Vodafone handsets, the data signal is identical (i.e. practically zero). I have a tracker installed on my handset which was a Godsend a year ago when I dropped it in a remote location, and I managed to locate it from my PC. Now it no longer works reliably where there is a poor signal.
        Maybe it’s time for a move away to EE…!

    The network coverage may exist (in theory) but network availability is another matter. Having toured the UK extensively including Wales and Scotland there are so many places where there is no Vodafone coverage and 3G is like vapourware. I have to use a Sure Signal box at home to get a signal, even that is not perfect. I am not picking on Vodafone they are my provider of choice the others seem no better. Cross the channel and there is a strong 5 bar signal and plenty of capacity everywhere.
    Am I the only one to feel this way?

    This is a great web site as Ive searched for ages to discover a reason that my mobile phone fails often to receive incoming calls with a Tesco Sim – I have seen here that the Tesco Network is Virtual – When I use my phone on Orange now EE I have no problems and The EE Network is real and giving me a more reliable connection. It may well be that other users in different locations and using different mobiles of course can get different results but I will be sticking to main and real networks in future. My reason for using Tesco in the first place was the reasonable price of the calls, however as my business depends on my answering calls quickly then price is not relevant against quality of service. Well done for this most informative site please keep it up to date as some of us out here want to learn or need to learn ……

    orange and T-Mobile have had native 3g cross native network (it picks the best signal now) now for last 3 months please correct your list

    apart from that list is very good

      Hi Karl,

      I'm not sure it is true that MVNOs cannot change the number afterwards: for example giffgaff do this all the time. Though perhaps there is a limitation on the Talkmobile system? I'm afraid I can't really advise beyond what Talkmobile customer services can tell you, sorry :(
