mark (@PieFaceMark) reported from London Colney, England@O2 hello. I have just moved over to O2 and am considering buying a phone from the company Oneplus. I have read that Oneplus phones don't work with the O2 5g network, is this correct? I don't want to buy the phone then realise I can't receive 5g. Thanks in advance

Daniel Appelquist (@torgo) reported from London Colney, EnglandDo you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England@O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to.

Cody (@CodyButton77) reported@O2 STILL charging me for a phone contract that I finished payments for in December 2025.

David (@davidlondon92) reported@O2 I’m roaming in the US on my ultimate plan and the 5G is painfully slow. I just realised you cap the speed at 2 mbps, which renders it pretty useless. Can I even buy a bolt on to remove the throttle? Not sure why I pay for an ultimate plan if your speed is so abysmal
