I've been an O2 cutomer for ten years, and currently have three handsets, and am seriously thinking of leaving O2.
Over the last four or five days I have found it hard to contact other O2 users. Phoning my wife or son goes straight to voicemail, and after lining up the phones beside each other, they all have full signal, 3G and 2G. It also happened with several friends who would have been on different cell towers.
I have tried diasbling data, still the same. three out of five calls go straight to voicemail.
This has happened before, but usually a reset of network settings and/or rebooting the phone/s sorts the problem out. Not this time.
Texts have also taken between 12-24 hours to come through.
Phoning landlines works just fine. The phones I have are an iphone 4S and two Xperia S'.
I've phoned O2 several times and get a metaphorical shrug "All is showing fine here".
Looking around the web I see various theories about O2 prioritising data over voice. But this still happens even when I completely disable data.
I'm at my wits end, and if this cannot be resolved, would I have grounds for early contract termination?
