  1. Changing mobile network? If you’re keeping the same phone but changing to another network, it might be necessary to first unlock your handset. See our guides to unlocking an iPhone and unlocking a Samsung Galaxy handset.
  2. Coverage is identical on many mobile networks. Many networks share the same coverage provider: you’ll get identical levels of coverage when using any of these networks. To give an example, ASDA Mobile uses coverage from EE and giffgaff uses coverage from O2.
  3. Keeping your mobile number. If you’re changing mobile networks, it’s super easy to keep your current phone number. Once you’ve ordered your new SIM card, contact your current network and ask them for a PAC Code. You can then pass this PAC Code on to your new mobile network and your phone number will be moved over on the next working day. For more information, see our guide to transferring your mobile phone number.

  • Hi Ken,
    Great information thank you.
    Have recently tried plusnet alongside EE same location and phone, plusnet poor in comparison ie indoors no service at all whilst EE is stil 4G capable. I’m told this is because plusnet does not have use of the 800mh band.
    So you know if Asda mobile is the same or does Asda have the 800 band and will work as EE?
    Cheers
    Robin

    • Hi Robin,
      Thanks for your comment. I know that EE have certain restrictions on things like the maximum download speed their MVNOs are able to access. However, I’m afraid I don’t know all the details about 800MHz (band 20) coverage and which MVNOs are able to access it (e.g. I’m unsure if this relates to 4G Calling, which is only available on EE and BT Mobile at present). Sorry about that!
      Ken

  • I’ve been using O2 PAYG for over a year and have only topped up once (£10 when I started with them). I still have about £3 left. So it is untrue that you have to top up by at least £10 every 6 months. When I asked O2 why they hadn’t enforced the 6 monthly £10 top up they said it was because the SIM they gave me is not subject to the top ups and that O2 have changed the rules since I subscribed and now they do charge and that providing I keep using their SIM every so often they will not cut me off or charge me more. I’m not sure about that because from what I have read on their website over the years there has always been a minimum £10/six monthly top up rule with O2.

  • Seems that you have to pay much more if you use a mobile phone rarely nobody is keen on you doing this the providers want us all to be phone zombies so they make it “seem ” cheaper to reel you in! No wonder the younger folk spend all their time on phones, wanting to get their money’s worth!
    I am just looking for a payg sim for smartphone that will accept £10 and keep going until it runs out even if you have to use it once a month! Is there one?
