I live and work in central wellington where my old S2 had no problems with any mobile data connections. Admittedly this was on XT but coworkers here have Vodafone and 2D phones and they also work fine.
My S3 on the other hand seems to be flakey as to whether it will connect to 3G or not.
When I first got it it took half an hour and a few reboots before it would connect to the 2D data network, I thought 'no worries, this is just what happens when you connect a new phone to their system'.
Now this morning no matter how many times I toggle 'Mobile Data' on or off, or number of reboots, the phone won't connect to the data network.
Is this a known issue or is there something about 2D data that I'm missing? Other than a factory reset is there anything else I can try? I can't imagine a factory reset will fix anything tbh.
