I’ve been having a rather troubling (but hopefully solveable) problem with my new 3G iPhone. Several of my incoming calls have been going straight to voice mail. The phone isn’t even ringing.
This is happening when my line is free, and when I’m showing adequate signal bars to receive a call.
I’m on the phone with AT&T Mobile support right now, and they said they’re tracking this problem with iPhone service. It appears to be happening when your iPhone is set to be on the 3G network. Apparently 3G isn’t as good for voice as it is for data.
Is this happening to you? Call AT&T! AT&T Mobile is collecting examples of this problem occurring. I’ve entered a trouble ticket for my problem. But if this is happening to you, call AT&T (611 on your iPhone) and let them know that you’re having the same problem. They have a master trouble ticket going on this, and they’re encouraging people to report the problem. The more examples they have, the better they can diagnose and fix the problem (so they say).
When you call, it helps if you can cite a specific example of a call you missed that you should have received.
Recommended tip: If you’re missing some calls, be sure to deactivate the 3G network on your iPhone when you don’t need it to browse the web. (Settings -> General -> network, then click “off” next to “enable 3G”)
This will also save on battery life.
Apparently while you’re not on the 3G network, it’s pretty tough to take a call and browse the web at the same time. I can live with that particular tradeoff for now, as long as I’m receiving all the calls I should be receiving.
