  • LaurieAF1 Laurie (@LaurieAF1) reported

    Hi @tescomobile my SIM card is broken/damaged have tried all the obvious fixes. How can i order a new one with my current number retained? I can't call any of the Tesco numbers as I have no service, coming up as no network detected thanks

  • jmh3004 ⭐️ Jo Hogben ⭐️ (@jmh3004) reported

    @tescomobile Trouble shooting is of no help. I find it disappointing that you actively sell something on a 3year device contract which then only has 24mth warranty. I’ll see if I can get any help from Apple direct.

  • HattyDevon DevonBows (@HattyDevon) reported

    @tescomobile So what’s happening in Torbay!!!! No signal for months now 😡

  • drjohnhmiller john miller (@drjohnhmiller) reported

    @tescomobile SIM issue. New SIM but Doro phone wants new code 4 numbers. Why? PAYG trie SIM credit. Bought today 99p.

  • PrivacyMatters Privacy Matters (@PrivacyMatters) reported

    Made the mistake of moving family mobiles to @tescomobile - utterly dire coverage and quality of service. It’s soooo bad I’m facing quite an early termination fee but the service is just so dire I cannot keep the mobiles with them. I could not recommend them.

    @tescomobile Hi. Having a few issues. Moved from Giffgaff who also used 02, had a full very fast 5g signal. Now I have 4g+. I have your 5G sim and everything is tuned on in my phone, I'm lost. I was told I would get the same as Giffgaff because you also use o2. 5g is in my area.
