Upgraded from the Desire to the One back in June. Ever since, I've barely been able to use mobile data, and it's essentially just used on wi-fi, making it a bit pointless. I've spoken to O2 via online chat, on the phone and written to them. I've taken it to a shop, and all anyone can do is check the internet settings, which is the first thing I did when I got the phone. I've also had a new SIM, but the problem is still the same. However, it works fine with the missus' EE SIM in there, at all times. My missus has the same phone, and has zero problems, at any time of the day. Wish I'd have taken my number and gone to EE, instead of upgrading.
The internet works fine okay in the morning, maybe until around 10:00am, and then it just doesn't work at all. I can't load anything. It won't even download pictures in MMS messages. It's been this way every day since June. 10:00am onwards - No mobile data. The arrows flash at the top of the screen, and the E/H/G/3G etc are always there, but websites don't load properly, messenger doesn't send or recieve messages...
I feel I've exhausted all options. I'm pretty certain I'm going to just bin my SIM and buy an EE or Three SIM and use it as PAYG. I'd rather not lose my number though, as I've had it for 11 years, but I'm fed up of having a phone that I should be able to access the internet with on the go, but can't.
