Leon Smith🇬🇧🇪🇺❄️ (@leon_dave_smith) reported from Harlow, England@tescomobile @O2 any coverage issues in CM20, been terrible yesterday and today, signal 4G keeps dropping out
-
Chris Ruggles (@chris_rugs) reported from Great Yeldham, EnglandHi @O2, just a heads up...me and thousands of others will leave your network if you advertise on GB news. Have a long hard think about what you will be funding. #DontFundGBNews
-
Simon Hemmings (@SimonHemmingshj) reported from Chelmsford, England@O2 @GarethTurpin I appreciate your personal message. However, I now remember why I left you last time, lower than average service, and now a 17.3% total price increase, which is disproportionate and completely knobbish if you ask me. @BBCNews
-
Richard Astley (@LongshanksE10) reported from Bishop's Stortford, England@o2 I ,along with seemingly many others, wish to know why your 4G has been virtually useless over the last week or so please, or better yet, when the service will improve, but you don’t seem to be replying to anyone. Please help.

CLAIRE WALMSLEY (@MissClaireW) reported from Halstead, England@O2 Yeh you keep replying to people with this, & yet the link you sent either directs back to social media, or continues the issue of login problems... so... ?? @virginmedia @O2
-
beverley fox (@1011FOXEE) reported from Takeley, England@O2 I am trying to apply the discount I get for working at Tesco,it won’t let me use my email as used for my daughters account,help!!
-
Ashley Leggett (@ashley_leggett) reported from Great Leighs, England@O2 The fact it’s in 3 seperate locations, where my current projects are located, suggests it’s on your side. To use the excuse that there is too much traffic is also ridiculous as means you have over sold your network.
-
Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England@O2 Sounds easy doesn’t it!! Every call is from a different number, it wears me down, in excess of 20 yesterday all blocked & inadvertently called a couple back in error trying to block late at night with brain fog. So cross!!
-
Ryan_Schaverien (@RyanSchaverien) reported from Chelmsford, England@O2 Extremely slow data coverage for the past 3 weeks.... any help?
-
CLAIRE WALMSLEY (@MissClaireW) reported from Halstead, England@O2 any resolution to your app not working, logins just go back to the same email verification page? So many people posting & no answers?
-
Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England@GlassBeadsLotti @O2 Thanks - trouble is it’s not a fault with the phone; service providers have got to up theirs game to stop this happening!!
-
Jacob Wood (@j4cobwood) reported from Harlow, England@O2 I need support with my network, I’ve tried everything that the website says, my calls won’t connect and when they do the sound is cracking and poor. Most of people trying to call me can never get through either. This has been happening for months now
-
Julian Little (@JulianLittle4Ag) reported from Little Dunmow, EnglandApologies to anyone who has tried to call me at the back end of this week. Badly let down by the useless service @O2 who are now saying that it will take ANOTHER 3 working days to move my number 🤬.

-
Andy Lane (@hadhamlane) reported from Bishop's Stortford, England@O2 ...and then when you’re signed up they change your deal to make you worse off. #O2 reducing the friends & family discount for a loyal customer is the last straw for me.. #O2
-

-
𝐀𝐛𝐛𝐞𝐲𝐠𝐚𝐥𝐞 (@AbbeygaleRose) reported from Chelmsford, EnglandBeginning to regret renewing my contract with O2, their coverage in Chelmsford is awful. My 4G works about 20% of the time. @O2
-
James Sharp (@JamesSharp87) reported from Witham, EnglandHello @O2 I’ve accidental damage to the rear of my iPhone 11 Pro Max. Only had the phone 3 months so will it be covered under warranty?
-
Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England@O2 the answer to that question is primarily no. I would have to leave Virgin as a HOME customer and then sign up as a business customer? What about my TV package?

Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England@techdotintel @virginmedia @O2 I'm a virgin HOME customer and an O2 business customer but I don't qualify

Paul Tomlinson (@Tommo_Ov_Tarn) reported@O2 It’s been poor ever since I ported my number over to O2 I have made many calls to O2 and you are looking into it, but I am getting reports of not being able to message or call me and the data is sooo slow its painful
-
Claire Kennard (@clairelkennard) reported@O2 Thanks- after 3 LONG phone calls with your customer service agents I think it’s almost sorted… the lady I spoke to this evening was exceptional, she was so helpful. Still need to speak to fraud team tomorrow and want to make sure this can’t happen again!
-
wendy devyea 🌸 (@Wendy_jDarling) reported@O2 please see DMs as this is urgent .a customer service agent has accidently disabled my sim
-
Joe Gibbs (@JoeGibbs2) reported@O2 To many phone calls to an automated switched board to eventually get through to Somone to not have this sorted multiple times is so poor . I’ve been told today it could take up 7 days to which I’ve said if not sorted in next 2 days I’m closing my contract and going back to three
-
Lou Mc (@LouiseM30692137) reported@O2 what are the chances of ever getting a half decent signal to make a phone call anywhere in WR1 without it dropping out after 30 seconds?
-
Ronnie (@ronak_malde) reported@O2 I am writing to urgently seek clarification regarding a refund that was due to be credited to my bank account. The refund was initiated on May 9, 2026, and I was informed that the funds would arrive within 3-5 business days. As of today, the money has still not been returned to my account. My experience with your customer service channels thus far has been incredibly frustrating. The primary reason I chose to migrate to another carrier was due to poor service, and this current delay only confirms that I made the right decision. Given the lack of flexibility and the difficulties I have faced, I can no longer recommend your services to others. If you feel that you have it in your heart to give me back my refund, please reach out. If not, have a meal at Wagamamas on me!

Chris.SE (@ChrisAO123) reported@O2 So @O2, here we are in the middle of April and the Community is still not working, so when will it?
