    Finishing with @O2 after 10+ years due to being messed around / fleeced at the last minute before I left to travel abroad for a year. How do I cancel my contract from abroad? I’m not willing to pay for the international minutes to call. Can a family member do this on my behalf?

    @o2 Hi O2! I switched to a SIM only contract, but the 4G data is awful: in many areas where there is full signal and a "4G+" symbol at the top , the data just doesn't work or is like 2G speeds. Other areas are ok. Any idea what's happening?

  • Robhodson44 Rob Hodson #44 (@Robhodson44) reported

    Does anyone else on @O2 have constantly bad phone signal?! Pretty much every call breaks up or shows ‘Call Failed’ only 3G at home when not on WiFi #o2
