    @tescomobile have to say you have fantastic customer service. Messaged one staff member early this morning and then chatted to two more. They helped save my daughter’s birthday as I’d clicked on the wrong colour phone for her upgrade and didn’t realise until it came yesterday 😬

  • C1S666 Chris🇬🇧🇬🇧🇬🇧 (@C1S666) reported

    @tescomobile any idea why my iPhone 12 mini keeps losing its 4g internet. I have to reset my network setting 3 or 4 times a day.

  • Stuxwarren Stu (@Stuxwarren) reported

    @tescomobile Whenever my phone is on 4G it always run slow, surely it shouldn’t? I know it’s not 5G speed but still

  • MadManDrivel Simon_W (@MadManDrivel) reported

    @tescomobile Yeah- I used the coverage checker to find out it’s STILL not working. What are you doing to compensate customers?

  • Steffan_McMahon Steffan McMahon (@Steffan_McMahon) reported

    Well after many many yrs with @EE since they were one2one its time to leave the network and join @tescomobile. In times of the Cost of Living crisis you got to go with the cheaper provider who can offer the same phone and sim equivalent. Loving my @SamsungMobile S22 Ultra :)

    @tescomobile I just recently moved and it keeps saying service error?? I know I recently moved from a place that had 5G to a 4G place so idk if that makes a difference??

  • AndrewG1128 Andrew Gardner (@AndrewG1128) reported

    @tescomobile hi,I ordered a new phone yesterday as a new customer & been sent tracking information but the numbers I have for tracking says invalid.

  • TwithaP MrsTwithaP (@TwithaP) reported

    @tescomobile Done this online before & postcode specific is ok. I can walk down the road and it goes to no signal, if I'm driving around its the same. I can have full signal & the next minute it cuts out & I've got nothing! Whole family on Tesco having same problem, it's all over Cheshire!!

  • scotts_land1 Scotts Land (@scotts_land1) reported from Glasgow, Scotland

    @tescomobile I can't make any calls or receive any calls on my mobile. Im a contract user. Another phone was used to check and it beeped the first time then number not recognised the second time.. Are you having issues with signals or connections??

  • Stuxwarren Stu (@Stuxwarren) reported

    @tescomobile in my new address it keep saying I have 4G but saying service error like I would have no service??
