    Five iPhones and one iPad all tested at my house yesterday on @O2 , little or no signal. @O2 claim it’s my sim or my phone. Unable to make calls unless I use WiFi call which isn’t a fix. Anyone else struggling around Manchester area?

  • Razza348 Razza♤ 🇬🇧 (@Razza348) reported

    @O2 I switch my 5G sim card from a S20+ 5G to a S21 Ultra 5G I can only get 3G signal

  • CazCronin Caz Cronin (@CazCronin) reported

    @o2 Hello. I had an email recently saying the problem with signal in my area has been fixed. But it hasn’t. I still can’t access any 4G data or phone signal in my house and it’s been months!

  • HanBakeyBaker Han B (@HanBakeyBaker) reported

    @O2 Can't ever get signal here, yet my partner who is with @EE has amazing signal. That link says the nearby mast is broken. Been "broken" a long time!

  • DebinNDevon DebinDevon (@DebinNDevon) reported

    @bigslick172 @O2 We're with @O2 & find them really good especially in this area. Obviously not the problem you're having but I hope all goes well. I'm sure they'll help resolve the issue. 👍

  • 360env 360environmental (@360env) reported

    @O2 I have Samsung S6 - not on the list. But I also want my signal back because that is what I am paying for. Why can you not tell me when this will be resolved? Been weeks since it went down.

    @bt_uk not saying your internet is useless but a download over WiFi 44 minutes. Using mobile data through @O2 10 minutes…. Another 25 hours down to 10…. Thank god for O2!!!
