I called ATT before the trip to make sure international roaming was enabled and the guy said as long as the phone is international it should roam fine. We'll, I get full bars but each time I try to place a call the message immediately pops up "Not registered to network". I've rebooted the phone, airplane loses it, etc. I even tried going into the mobile network settings and selected manual and tried choosing one of two listed networks to no success. Any idea what the issue is guys??
