    @tescomobile It’s gone back to E (edge) You’ve done all you can. It’s now either the software update from @AppleSupport or despite claims on the @O2 website the mast is still no good. O2 aren’t responding, and Apple won’t acknowledge that others have signal problems after the update.

    @tescomobile can you explain common sense behind your process for sim replacement? Why do you cancel current sim before new sim has physically in user hands? Leaving all without services sometimes for days? Your technical support is poor to all what they advising is to wait!

  • andygray1401 Andrew Gray (@andygray1401) reported

    3months now of no signal in my area where I live on @tescomobile.. Absolutely a joke when I'm paying over £100 quid a month to them for our phones! #notbothered @tesconews

  • GittingsTina Tina Gittings (@GittingsTina) reported

    The most appalling customer service from @tescomobile Without phone service for 3 months. Literally hours of time spent on their chat, phone, complaint form and in store. Requested several times escalation to a manager but never a call back.

    @O2 @giffgaff @tescomobile why is there very limited coverage both phone and data on the network, 3 different devices all have same issue. Liverpool area

  • hambletonred Richard (@hambletonred) reported

    Switched to @tescomobile and one week on from my number being ported across I still can't make calls. Daily conversations with "customer services" absolutely hopeless. Awful experience so far. Please help! @WhichUK

  • ont_stoop TheDarkenedDoorstep💙💔 (@ont_stoop) reported

    @tescomobile signal reception isn't strong were i live(a hollow)-but i thought a simple text message would get through despite weak signal. I have a basic model alcatel 1- not happy with the bloody thing=- any ideas as to why messages are failing to send/recieve??

  • MrsDanielleD99 Danielle Davison (@MrsDanielleD99) reported

    @tescomobile what is going on with your business SIM cards? Moved multiple business SIMS from O2 to Tesco Mobile. Every call received showing as NO CALLER ID. Multiple calls to Customer Service who have finally admitted it is a known issue but no fix. How is this acceptable?

  • AllanMcLaughlin Allan McLaughlin (@AllanMcLaughlin) reported

    @tescomobile Please DM me... no one is getting back to me. I want my old phones ported over ASAP. It's been over one week. Also, the form you DM me doesn't work.

  • andygray1401 Andrew Gray (@andygray1401) reported

    @tescomobile Liz. @tescomobile are very much aware, as do your engineers. The multimillion pound company @Tesco have been telling me this since November 2022. #embarrassing Happy to take my money each month. But give me poor excuses like this each month
