    I’ve had no signal all day Kmt, @O2 sort it out man

  • NO128839973 NE1 (@NO128839973) reported

    @O2 hello. New customer. Porting old number fails with “something went wrong”. Not a good start.

  • PrintIsntDead Alan Anderson (@PrintIsntDead) reported

    @SteveStormzone @ThreeUK @O2 Ha ha I know. Worst thing ever

  • nicofell N i c o F e l l (@nicofell) reported

    @PrintIsntDead @ThreeUK @O2 Considering the same mate. Just so much money. Plus when I’m in London, Three’s network seems terrible as well.

  • chris_roarty Chris Roarty ⋈ (@chris_roarty) reported

    Seriously contemplating leaving @O2. Can’t get a signal almost anywhere anymore. I already switched from another provider because O2 had the best connection in my area. City centres and rural areas have no chance now, so disappointed.

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @envance @O2 @envance Your Mum needs to call to customer services & tell them she would like to cancel the contract. They will get her through to their colleagues in Retentions but your Mum needs to pass security first before customer services can transfer her to retentions.

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @r_you_rosa @O2 If they still haven’t meet your needs, retweet your complaint with BBCWatchdog, WhichUk, ofcom and Martin Lewis tags. The network is horrendously bad.

  • filthy_richey Tom (@filthy_richey) reported

    @O2 any word on when the signal issues in the North Walsham area will be resolved?

  • CharlotteFry96 Charlotte Fry (@CharlotteFry96) reported

    @o2 as I haven’t been able to speak to anyone since I was promised a call back this eve I want to cancel my new contract & move network. Your customer service leaves something 2 be desired esp as I think I heard 1 of your employees laugh about my frustration while on the phone

  • magsfoxyloxy Maggie (@magsfoxyloxy) reported

    @O2 still paying for international roaming and still not even getting 3G, let alone 4g. Never ever travelled to Orlando before and had such bad connectivity. Tried selecting network, won’t let me. Tried turning phone off and on and still doesn’t connect. So frustrating
