Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

@O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

@O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

@O2 i have a problem with my network on samsung galaxy s22 ultra, I cannot receive or make calls or texts and i have no data connection on my Unlimited eSIM. I CAN'T request help from O2 as i can't call via 202 or any other number as it just drops the call instantly. It started 18th November 2025 early morning. Please can you help me reset my eSIM or check provisions are set up on my account for 4G/5G as my eSIM is constantly connected to WCDMA (900).

Counting down the days until I can leave @O2 I never get signal, I can only use WiFi at home. What is the point in paying nearly £70 a month to only use a mobile phone at home. I might as well have a landline. I work in Central London, in this day an age a phone is needed. 😡

@O2 Hi. I have been trying to get through by phone to cancel my contract - hold times are too long and no response via online chat. How do I cancel without having to call? I have my PAC code and have transferred my number - is that enough?

I swear when living in Kent and on @o2 going through Tonbridge and paddock wood the reception is a joke. It's like being in a dead end location with no service. I thought O2 weren't meant to be good???
