On very unpopular views,when I’m having down/depressing thoughts or ‘keep it down’’be humble‘’I’m in control of you’’you don’t matter’ oppressive thoughts or just plain(excuse the expression)islamic thoughts,I know my O2 sats are down or CO2 levels in room are high. Long COVID.

So glad I have @O2 refresh, had an @Apple iPhone since the iPhone 3GS but with a company bowing down to the UK Govt and no longer ensuring maximum privacy of my data, my iPhone 16 will be getting swapped over next week, and no longer will I have an apple account @AppleSupport

Hi @O2, my office is based in St Martin's Lane and I've barely been able to use my phone for over an hour. Showing full bars for 5G, but receiving zero service. Local outage?

Hey @O2 why is my network down? What’s going on?

3m

Had #VirginMedia down for a few hours today due to a fault. So, using #O2 mobile data and have “5G” and yet it struggles to load a tiktok video. ******* trash service.

4m

Hello #O2 - Calling, store visits, Website is down and call center employee could not be bothered and hung up on me. Do better please. It’s not that hard. #CustomerEngagement

4m

Let down again by @sainsburys useless Smart Shop App. Get to the end of my shopping (£120) and the last items won’t populate in the App. Is it useless @O2 three-bar 3G signal in there? The useless @o2 WiFi? I don’t know. Had to unpack whole trolley and put through manually.

5m

Annoyed at @GreggsOfficial and @O2 once again - redeemed my voucher for a free sweet treat, got to till and lo and behold, not working. No explanation as to why, just a flat out refusal. No apps working, they said. 🤷‍♂️

5m

Day 9 of my sim card not working @O2 never ever ever migrate your number from one sim to another sim including within the sake network. It doesn't end well.

5m

Worst network outage of the year in London today and yesterday! 😤 Struggling with #EE, #O2, and #3

5m

Usually vibing with @O2 customer service but getting no where from 6pm-10pm was not fun and also they cancelled my order? So now I’m an oculus down and deeply saddened :( #disheartened

5m

I love o2. Got told to call them when my service is down/extremely poor okay

5m

Why is data not working on o2 all of a sudden I have 5G and 3 to 4 bars of signal it should be working and loading not spinning in circles and not working on anything is there an issue on the network?
