BT offers SIM-only mobile deals with inclusive BT Sport, 5G coverage from EE and Family SIM discounts. You’ll get a £5/month discount with BT Broadband.

In the UK, BT offers mobile phone SIM cards and handsets with access to 4G & 5G coverage from EE. You can get a BT Mobile SIM card from as little as £5/month, with a range of Family SIM offers and Pay Monthly phones also available from BT.

A key benefit of BT Mobile’s SIM-only deals is the inclusive access to the BT Sport app on plans from £15/month (or from £20/month if you’re not a BT Broadband customer). You can also get a £5/month discount if you’re a BT Broadband customer, along with double data if you have a BT Halo plan. There’s also a 20% discount when you take multiple SIM cards through BT’s Family SIM offer.

In this article, we’ll review the BT Mobile network. We’ll look at BT’s SIM-only deals including the key features available and how you can save with the multiple offers. We’ll also look at the coverage available on BT Mobile and how you can keep your current phone number when switching to BT Mobile.

Prices From: £5 per month (for BT Broadband customers)
£10 per month (without BT Broadband plan)

BT Mobile Plans

In the UK, BT Mobile and EE sit alongside each other as different brands in the wider BT Group. You’ll get access to the same coverage on both networks, but with a slightly different focus (e.g. cheaper SIM-only deals are available on BT Mobile).

SIM Only Deals

One of the key advantages of choosing BT Mobile is the range of low cost SIM-only plans that they have available. BT’s SIM-only plans start from £5/month if you’re living in a BT Broadband household, or from £10/month if you’re using another broadband provider.

The following table shows BT Mobile’s SIM-only deals, available on a 24-month plan:

NetworkMinutesTextsDataMonthly

BT MobileUnlimitedUnlimited10GB£10.00

The prices shown in the table include a £5 monthly discount for BT Broadband customers. If you’re using a different broadband provider, you’ll need to add £5/month to the price.

If you want extra flexibility, BT also offers a range of shorter 12-month SIM-only deals. These start from £7/month for BT Broadband customers:

As before, you should add an extra £5/month to the prices shown above if you’re not a BT Broadband customer. At present, you can get a £90 reward card when you sign up to BT's Fibre 2 broadband. It may therefore be worthwhile getting BT’s fibre broadband service at the same time as signing up for BT Mobile.

See BT Mobile SIM Only Deals →

All of BT Mobile’s SIM-only deals now include access to 5G at no extra cost.

Family SIM

If you want multiple BT Mobile SIM cards (e.g. for different family members or for additional devices like a smartphone or tablet), you can get a 20% discount through BT’s Family SIM offer.

To give an example, you can start by choosing a primary SIM card that costs you £20/month. You can then add additional SIM cards to your account with a 20% discount on the price (e.g. you’ll only pay £16/month instead of £20/month for an additional SIM card with the same allowances).

The following image shows a worked example of how you can save money with the BT Family SIM offer:

In addition to saving 20% on the Family SIM cards from BT Mobile, you’ll get a combined bill for all of the SIM cards on one account. The additional SIM cards are also subject to a shorter 30-day rolling contract instead of the full 12 months or 24 months. This allows you to add or remove extra SIM cards at any time with more flexibility. You can also manage the parental controls and content settings on a per-SIM card basis.

You can use the interactive tool on BT’s website to see how much a Family SIM package will cost you.

Mobile Phones

If you’re looking for a new smartphone, BT also offers a range of mobile phones on a 24-month contract. They currently sell a number of 4G phones from manufacturers such as Apple, Samsung, Google, Huawei, Oppo and Doro.

Unfortunately, it isn’t currently possible to get a 5G phone on BT Mobile. This is because they only sell 4G phones. If you’re looking for a 5G phone, BT will instead suggest that you get it from EE. When you buy selected 5G phones on an EE Smart plan, you’ll get the first 6 months at half price if you’re a BT Broadband customer.

For a full list of handsets offered by BT Mobile, please see the official BT website. As with BT’s SIM Only deals, you’ll get a £5/month discount on all handsets if you’re a BT Broadband customer. You can also get double data on mobile phone contracts if you have a BT Halo plan.

Pay As You Go

Unfortunately, BT Mobile doesn’t currently offer any Pay As You Go deals with no need for a credit check. If you’re looking for a Pay As You Go plan, you can get one from EE instead. EE is also a part of the wider BT Group.

BT Mobile Features

BT Sport App

If you choose a BT Mobile plan costing £15/month or more (£20/month or more if you’re not a BT Broadband customer), you’ll get inclusive access to the BT Sport app on your mobile phone. This allows you to watch all of the BT Sport channels, as well as watching on-demand action from the UEFA Champions League, Premier League, FA Cup and more.

You can register for your inclusive access to the BT Sport app through this page on BT’s website.

The inclusive BT Sport mobile app access doesn’t cover your data usage through the application. This will still count as normal towards the download limit on your plan. It also won’t allow you to watch BT Sport on other devices such as your TV or laptop.

If you’d like to watch BT Sport on the big screen, see our guide to the best BT Sport deals.

BT Broadband Discount

If you have a BT Broadband connection in your home, you’ll get a £5 per month discount on all BT Mobile plans. This includes on SIM-only deals, Family SIM and Pay Monthly phones. It isn’t necessary to be the BT Broadband bill payer to get this discount – you just need to live at an address that has BT Broadband installed.

You can qualify for the £5 per month discount with any of BT’s home broadband plans. This includes standard broadband, fibre broadband and full fibre broadband.

If you have BT Business Broadband set up at your address, you won’t qualify for the £5 discount as you need to have a consumer broadband plan. Instead, you can look at BT’s Business Mobile service instead.

Double Data with Halo

If you have BT’s flagship Halo broadband service, you’ll get double data on all SIM-only and Pay Monthly plans from BT Mobile. For instance, you’ll get 20GB of data on BT's £10 SIM-only plan whereas other BT Broadband customers will only get 10GB of data.

The following table shows some of the double data deals that are available exclusively to BT Halo customers:

If you’re a BT Broadband customer without BT Halo, check online to see how much it will cost you to upgrade. According to BT, an upgrade to Halo might be available from as little as £1/month. This will give you access to Home Tech Experts and BT’s Keep Connected Promise. If you choose BT’s Halo 3+ plan, you’ll also get Hybrid Connect, the Complete Wi-Fi service and BT’s Full Fibre Promise.

Unlimited Data with Halo

If you’re a BT Halo customer, you’ll also have access to an exclusive unlimited data plan on BT Mobile. Available from £20 per month, it gives you unlimited data with uncapped download speeds on 5G. You’ll get inclusive access to the BT Sport app with it, along with unlimited UK calls on your BT home phone.

According to BT, there’s no fair usage limit for unlimited data in the UK. BT says “it truly is unlimited”.

For more information, see our guide to unlimited data on BT Mobile. You can also read our full overview of unlimited data plans in the UK.

Free BT Wi-Fi

Customers joining BT Mobile will also receive unlimited access to BT Wi-Fi hotspots (previously known as BT Openzone).

There are currently more than 5 million BT Wi-Fi hotspots across the UK. This makes BT Wi-Fi one of the most extensive wi-fi network providers in the UK. Locations with a BT Wi-Fi hotspot include shopping centres, train stations, cafés, restaurants, service stations and more. You can enter your postcode on the BT Wi-Fi website to find nearby hotspots.

A typical standalone subscription to BT Wi-Fi would cost you £15/month on a 12 month contract.

Network & Coverage

2G, 3G & 4G Coverage From EE

As a customer of BT Mobile, you’ll have access to EE’s 2G, 3G and 4G networks in the UK. This will give you 99% population coverage, with a signal available from BT Mobile in the same places a signal is available from EE.

Before you sign up for a BT Mobile plan, it’s worth double-checking the coverage in your area. You can do this by entering your postcode on BT Mobile’s online coverage map:

For more information, see our full guide to EE’s mobile network and coverage.

5G Coverage

If you have a 5G-ready plan on BT Mobile, you’ll also be able to access 5G coverage in 160 UK towns and cities. Like their 2G, 3G and 4G coverage, BT Mobile’s 5G service is also powered by EE’s network.

You can access 5G coverage at no extra cost on all of the following plans from BT Mobile:

  • BT Mobile SIM-only deals taken out since the 1st September 2020.

Tethering & Personal Hotspot

Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with another device (e.g. with your laptop or tablet). It’s often used as a convenient way to get mobile broadband on your other devices, without the need to take out a separate price plan and device.

On BT Mobile, the use of tethering and personal hotspot has been permitted since June 2016. This means you can use tethering and personal hotspot functionality to share your BT Mobile data allowance with other devices.

International Coverage

On BT Mobile, it’s possible to use your SIM card abroad through the international roaming service.

If you’re travelling to one of 47 European Roam Like Home destinations, you can use your normal BT Mobile allowances at no extra cost. This includes your allowances of minutes, texts and mobile data (up to a maximum of 50GB per month).

If you’re travelling to Andorra, Australia, Canada, China, India, Mexico, New Zealand, South Africa, Thailand, Turkey, the United Arab Emirates or the USA, you can pay £6/day for a BT Mobile Travel Data Pass. This gives you 500MB of data to use over a 24-hour period.

For more information, see the international roaming rates as detailed on the BT Mobile website.

Keeping Your Phone Number

If you’re changing from another mobile network to BT Mobile, it’s a straightforward process keeping your current phone number.

Start by asking your current mobile network to provide you with a PAC Code. You can normally get one online through your mobile network’s website or app, or by texting PAC to 65075.

Once you’ve gotten a PAC Code from your old mobile network, order your new SIM-only deal from the BT website. You can either give the PAC Code to BT when you sign up online or after your new BT Mobile service goes live. Once you’ve given the PAC Code to BT, your phone number transfer will normally be scheduled for the next working day.

For step-by-step instructions on how to transfer your phone number to BT Mobile, please select your current mobile network from the drop-down menu below:

  • It annoys me so much that people in fibre built areas get such good deals.

    Why not offer unlimited 5g to people who can’t get fibre!?

    So people are being upgraded to fibre free if it’s available and an opportunity to get 5g unlimited? As well as ones who are already on fttc getting opportunities to go to fttp as well due to fibre cities.

    I’m on ADSL and there’s no plans for my area to be upgraded to fttc or fttp but 4+5g are both available but 4G broadband is so in demand it’s basically useless and 5g is a complete rip-off. Ffs. Frustrating!!

  • Shame about the plans here, with BT still charging a premium for 5G access and keeping it so exclusive that only BT Plus customers can get it. This is despite Vodafone and Three offering it to everyone and having 5G on their plans at no extra charge…

  • Was considering bt sim only based on reviews by a number of pro reviewers. Then checked the reviews by customers on trust pilot and others. Not a chance. Why no mention of the abysmal customer service reviews ? I mean they’re totally shocking for a supposed British institution.

  • Hi Ken

    I’m thinking of joining BT mobile as I’m BT broadband customer,if I was to go ahead with the mobile contract what would happen if I canceled the BT broadband contract which ends in a few months time? Many thanks Steve

    • Hi Steve,
      Thanks for your comment and a very good question! I’ve tried looking into this a bit further, but wasn’t able to get any conclusive answers from BT. All I was able to find was a mention in their terms & conditions that they reserve the right to remove the discount from you (whether they actually do this, I’m really not sure). Your best bet might be to contact BT to try and get a conclusive answer from them (do let me know if you find out anything on this!).
      Thanks,
      Ken

  • Ken,

    Yes great deals from BT mobile, you should also point out in your reviews that BT have a massive credit checking problem. I have recently started to transferred my family from Vodafone to Bt mobile given the great deals they are doing. BT broadband worked well and we had a Bt landline for 30 years. After signing up two of the kids for mobile phones , they blocked my order for my wife phone. So that they can protect the company. As an ex-employee I like to be faith to BT. So if your family wants more than two mobile contracts don’t go to BT mobile.

  • Earlier today, while my boyfriend and I were in school he received a message after turning his phone on during lunch for the first time in hours which read that he’d used 401MB out of his 500MB in the month, then exactly 1 minute later he received another message saying that he’d used up all of his allowance! We were both shocked at how this could’ve happened considering he’d only had the phone on for a minute and we were both pretty sure that data can’t be used while the phone is turned off? Anyway, he turned it back off and that was it until we got out of school about 3 hours later. As we were walking back to his house (which is only about a 7 minute walk) he had his phone on, and during those 7 minutes with no apps running apart from one he somehow used almost 300MB causing him to rack up a bill of £35 (his cap is £40) with no warning whatsoever? The app he was using hadn’t even used 1MB in total when we looked on the mobile data usage! We told his dad when we got home, and he checked on the BT Website and found that almost all of the 500MB had been used today, somehow?! It’s unbelievable – is it broken or a scam, we don’t know?

    • Hi Ellis,
      Thanks for your comment – this is a really strange situation. My *guess* is there might be a background application using up all of that data (e.g. do you have any photo auto-upload services, or were there any automatic updates running at that point?). It’s worth checking your mobile phone’s data usage monitor and then comparing this to BT’s figures to see if there any discrepancies. If your phone’s data usage monitor shows a very different number to that shown by BT, then I’d definitely get in touch with BT to discuss the situation.
      Hope this helps,
      Ken

      • It said in the general mobile data usage bit that general applications had been using up the data, however it’s strange how 500MB was used up solely on that day and not on any other, even though all the phone settings had remained the same? BT was called and they insisted that it was his fault, that it must not have been turned off or something (even though it was) since they didn’t want to take any responsibility for it I’m guessing. We’ve turned off background app refresh now – maybe that was doing it, even if the phone was turned off? Oh well, hopefully it won’t happen again!

        • Hi Ellis,
          Yes, this is really strange 🙁 It might be some kind of automatic update (e.g. your apps or operating system updating themselves automatically) – ideally they should only really being doing this over wi-fi.
          Ken

  • THINK TWICE BEFORE YOU GO BT MOBILE. Beware of BT mobile’s massive hidden data & call charges. You MUST READ THIS if you ever consider a BT mobile SIM card. I got charged additional £100 for my first bill which came as rude surprise. Since realised that countless unsuspecting victims have found themselves in similar situation which is not informed at any stage before you sign on with BT. BT later told me I should have seen a link at the end of the activation confirmation email which advises about avoiding a surprise. You will be lucky to ever read it amoungst the mill of information in the email but still does not mention this massive charge. What BT refers to does not give any indication of the charges except to check “my BT moblie” How BT can justify charging £100 for going over my data allowance by 1GB is beyond me. I have complained but told it is my responsibility to check the small prints. I am not going to give up but I believe I owe it to others mobile phone users to inform them and spare them this travesty. My previous service provider slowed down my browser when I once went over my data limit but never charged me extra above my contracted amount. With BT you will ALWAYS be charged heavily if you go above your limit. In my case I was charged my expected yearly payment in just the first month! BT have now confirmed that I cannot cap my monthly data so that I do not pay any extra above the original contracted monthly amount.

    • Hi Kunsky,
      Sorry to hear about the problems you’ve experienced on BT Mobile. Just wondering if you’ve tried their Spend Cap feature? In theory, this should prevent the problem you’re talking about (your out-of-allowance charges won’t be able to exceed a limit such as £5/month).
      Ken

  • Wow Ken what a brilliant website. I have been looking for a PAYG deal for my father 91 years old, just about to get his first mobile. So helpful, I was beginning to despair trawling through all the companies on the web trying to answer all the very complicated questions that my father was asking, he was a Chartered Accountant, so very savvy with figures. Just so full of info, clearly set out and answering all my questions.. Thanks so much.

  • Hi all,
    Just a quick heads up that we’ve updated the article following BT’s recent price plan changes.
    – The 500MB plan is now £6/month (£11/month for non-BT Broadband customers)
    – The 2GB plan is now £11/month (£16/month for non-BT Broadband customers)
    – The 20GB plan is now £20/month (£25/month for non-BT Broadband customers)
    Previously, the tariffs respectively cost £5/month, £12/month and £20/month.
    Hope this helps,
    Ken

    I’ve had a 20 pound sim package for my s5 was working fine then all of a sudden data stopped samsung checked phone all good my sim will work data in another phone and another sim will work in this phone checked all apn settings etc nothing any help please

    • Hi Jason,
      This is a really curious problem – afraid I don’t have any obvious solutions to the problem. Your best bet would probably be to ask BT Mobile Customer Services (call 150 on your BT handset or 0800 800 150 from any other phone).
      Ken

  • Hi, I have bought BT broadband and now I use BT mobile for £5 a month with a discount. They say it’s a capped plan and if you use your 500mb, you cannot use anymore. But, on capped limit, it is £5 minimum and every month we get an extra £8-£10 bill because BT takes £1 for every extra MB. I have another contract with Tesco, with capped plan as well, and I never pay over my limit. Does that mean it is capped or BT is bad? I think maybe to cancel plan in the future? Thanks

    • Hi Stan,
      Thanks for your comment. I’ve taken a look at this a little bit further: it appears that BT has an option to add a “monthly spend cap” but there’s no way of actually setting this to zero. BT’s website says:
      “Limited to available caps. (Initial cap set between £5 and £100 depending on your credit status). Cap set at £100. Opt in to decrease to £5 or increase to a maximum of £200 (subject to credit status)”.
      It wasn’t totally clear to me whether this monthly spend cap includes your normal monthly charges. Have you asked BT what the cap on your account is currently set to? I’m curious whether you’re able to set your monthly cap to £5/month and whether this stops you from incurring any extra charges.
      With regards to out-of-allowance usage, BT does charge a rather hefty 10p/MB once you use up your allowance (this can very quickly add up to a fairly large bill). The best way to stop this from happening is to get it capped at BT (alternatively, your smartphone operating system might allow you to automatically stop the data connection once you reach a certain limit).
      Ken

  • Hi,
    I was really interested in the “SIM only Plan” with the £5/month discount if you already have BT Broadband. Only problem is that I actually have BT Business Broadband (we run a riding school, not a pub etc) so the BT registratation failed with an error message (something like “unable to complete form”). I can only assume, like many of BTs BB vs Busines BB offers, is that this offer is only for BT BB and not for BT Business BB. Can you confirm this? Thanks

    • Hi Rob,
      Thanks for your comment. As you say, unfortunately, the BT Mobile tariffs are only available to people who have BT Consumer Broadband. There is a separate BT Business Mobile service but unfortunately the tariffs there are a little bit more expensive (e.g. £20/month for 2GB of internet compared to only £12/month on the consumer offering).
      Ken

  • Hi Ken, you are totally brilliant. I’m so glad I found your website yesterday which answered all of my questions. I’ve been with Orange since Adam was a lad with no probs at all. Last Monday, having received a new SIM card from EE which after 22 hours in the phone still wasn’t working one of their guys made what he admitted was a very basic mistake and locked my Nokia C2 whilst migrating my number from card to card. This is after I’d spoken to four different EE staff to confirm the new SIM card would work, none of whom thought to ask for details of my handset. Now I’ve got to wait at least another seven working days for them to get me the unlocking code from Nokia. Grrr!

    In the meantime I’ve read lots of your info on how things work, e.g. I know all the contacts etc on my phone are still there without the SIM card in, I know I can use a 4g SIM card but it will run on 3G which my handset supports, what to do to change my network and keep my number and all about the BT mobile deals.

    Can’t thank you enough. Even ladies in their sixties like to learn! Thanks Ken.

  • One thing BT don’t tell you, and it took me a bit of pressing to find out, is that even though you have signed a 12-month contract, if you cancel or change your broadband provider in those 12 months, you immediately lose your mobile discount, i.e. your bill increases immediately by £5/month.

    Worth remembering.

  • Having to choose between combi SIM or nano is surprising. EE supply their subscribers with a universal card which fits all three sizes. Unless, of course, these are causing problems.

    • Hi Angus,
      Thanks for your comment. I’ve also received one of these trio-SIMs from Three: it worked OK when I used it as a Micro SIM. My only thoughts were that there’s a difference in thickness between the Nano SIM and other types of SIM card (it’s only a small difference at 0.09mm but nevertheless, it means having a regulation Nano SIM isn’t the same thing as popping out the centre part of a SIM card). Not sure if this ever causes problems – also, there’s people snapping the SIM card out of the wrong place and then damaging their phone by using an adapter (possible in certain handsets depending on how the SIM card slot is designed).
      Ken
