Re: iPhone Text Message Issue
Sounds like you did everything correctly to try and trouble shoot the new phone. However, the replacement phone is a remanufactured phone so it's possible they missed something re-building it. Might try another car if you can and/or video the results to prove to the Apple store it's not working is my only suggestion.
Update: forgot to mention to try the Reset, Settings/General/Reset. Try the Reset Network settings first then Reset All. Kind of a pain but worth a shot.
