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.
