From the subject line, is this a possibility? Im a avid phone user that likes to use different phones every so often. If i simply phones using the same SIM. Does my iphone data plan change automatically? or everything should work and no probs will happen? I've heard iphone and android uses the same data. Just wondering about WWM7.
It should work just fine, just note VVM won't work and you may get aggravating text messages but it won't automatically change it. I am using an iPhone right now with a *4G* smartphone personal unlimited plan just fine.
