Networks like giffgaff, Sky Mobile & Tesco Mobile piggyback on O2’s network for coverage.

The UK has just four network coverage providers: EE, O2, Three and Vodafone. Alongside them, there are a number of “virtual network operators” that piggyback on coverage from one of the four main networks.

If you’d like access to O2’s coverage on your mobile phone, it isn’t always necessary to be an O2 customer. That’s because you’ll also get an O2 signal when you’re using a SIM card from giffgaff, Sky Mobile or Tesco Mobile.

In this article, we’ll present a list of mobile networks that offer coverage from O2. We’ll start by looking at some of the best value deals with O2 coverage including SIM-only deals, unlimited data plans and Pay As You Go bundles. We’ll then look at each mobile network in more detail, including the specific features and plans they offer.

O2 Coverage: 99% UK population coverage
Networks Using O2:
Best Unlimited Data Plan: £20/month on O2
(with 5G coverage and 6 months free Disney+ or Amazon Prime Video)
Best Pay As You Go Bundle: 20GB data for £10 on giffgaff
(with 5G coverage, no contract & no credit check)

Overview Of Networks Using O2

Besides O2, there are currently three other mobile networks that offer coverage from O2’s network in the UK. These networks are giffgaff, Sky Mobile and Tesco Mobile.

If you’re using one of these three other networks, you’ll get the same coverage as customers on O2. However, you’ll pay a different price for your plan. You may also have different features and benefits included.

The following table shows a side-by-side comparison of mobile networks using coverage from O2:

We'd love to hear your thoughts and any questions you may have. So far, we've received 9 comments from readers. You can add your own comment here.

  • I live in a remote area and want to use 4g as my main broadband. O2 are the only ones who have a strong enough signal. They have an unlimited data deal, but the small print says you can only use it in a phone and not a ‘modem’. Seems crazy, as I could tether a phone and use just as much data, but it would be messy compared to a dedicated 4g router/modem… I’ll probably need about 400Gb per month.

  • Joseph hague said:

    I have been a giffgaff customer for a few years now,and have been very happy with it,until my internet connection went and there is no one to contact about it?

    • M bethell replied:

      You can look on giffgaffs website and email a adviser with you problem. To be fair I have been with giffgaffs for years and if I have ever had I problem it has been sorted out in a timely manner

  • I want a low usage tariff like O2’s ‘Classic Pay As You Go’, but I am confused by their terms and conditions.

    In one section it states you must Top Up every 6 months
    Classic Pay As You Go
    When you join Classic Pay As You Go, you pay for what you use, as you go. The minimum
    top up requirement is £10.
    ‘If you don’t top up, or add a Bolt On at least once in any six month period, your mobile will be
    disconnected and you’ll lose any credit on your account. If you want to be reconnected you’ll
    be given a new mobile number.’

    But in the Terms and Conditions paragraph 7.1. it states that you are only required to use the SIM every 6 months
    7.1. If you do not carry out any chargeable activity at least once in any 6 month period your
    Mobile Phone will be disconnected and you will lose any remaining credits balance on your
    Account. If you wish to be re-connected after this time you will be given a new Mobile Phone
    number.

    Do I have to only use the SIM every 6 months as it states. Or do I need to ‘Top Up’ £10 every 6 months as well as using the SIM?

    • Hi Grant,
      Thanks for your comment. This is a question that lots of people have discussed in the comments on my full guide to O2 Classic Pay As You Go. I believe the general consensus is this was sloppy wording from O2, and you just had to use your phone for a chargeable activity once every 6 months. However, if this is likely to be an issue, I’d recommend double-checking directly with O2.

    Hi Ken, Your article is very interesting. I have been on Tesco Mobile PAYG Lite for some time, at 8p per minute for calls and 4p for texts. I use a simple phone on this service for calls only. (I have a smartphone on the “3” network for data use). Can I really change to O2’s Classic PAYG tariff at 3p per call and 2p per text, with the only conditions that need to be satisfied are a minimum top up of £10 and one call must be made every six months. It sounds identical to Tesco Lite at 3/8 of the call cost, or have I missed something?

    Great article, very helpful. Having read this I’ve been able to make an easy comparison between all the O2 based providers and move to a SIM Only deal saving myself over £10 B month! Many thanks
