Check to see if you have a good signal. If not that may be the answer. Pulling the battery does do a reconnect to the cell tower and if it's seen it connects. Do you get a
" searching for service " message?
Hi! Thanks for the answer!
It happens all the time, in any part of New York City. I don't think that the signal strenght is the problem in itself. But, whenever I take the subway, when I leave the station and regain the signal, data connectivity is off and nothing but a battery pull would solve it. And the battery pull is 100% effective; it solves the issue absolutely and every time.
I thought it may be some phone-related issue, but I upgraded the OS to OS6 and the problem is exactly the same as before, with the only difference being that now, sometimes, a soft reset would work, instead of a battery pull.
For instance, using Logic Mail, I get the "unable to open connection" in a fraction of a second after I select the mail refresh. The phone doesn't even appear to be trying to connect to the network; it acts as if something within the phone config is disabled. The error message comes too fast to really seem that is trying to connect and not being able to.
I changed various APNs that TMobile uses. On each the problem is the same.
Any other thoughts you may share?
