Why are my messages being sent as text messages rather than iMessages to other iPhones?
I just got an iPhone 4s through Sprint (my wife also did). For some reason when I send her or other iPhones messages, they are being sent as "text messages." However, when she messages with other iPhones, they get sent as iMessages. We are both on the same account....I changed mobile numbers to iPhone and thought this would solve my problem, but didn't. Any help/thoughts would be appreciated! Thanks!
iPhone 4S, iOS 5.0.1
