So I just upgraded to the iPhone 4s from a 3gs on AT&T, anyway my wife can use the 3Gs on her Sprint SERO plan?
No, Sprint is a CDMA carrier, AT&T is a GSM carrier. Your phone doesn't have the CDMA inside of it to run on Sprint
I can't believe no one has asked why you aren't on the same carrier. Family plans are usually much better deals. Besides, Sprint sucks balls.
We we both on SERO cause it was dirt cheap ($30 per month including unlimited data) but the smart phone offerings sucked balls and I wanted an iPhone so I switched to AT&T. She basically doesn't give a shit and prefers cheap.
No way he's going to beat a SERO plan. Why didn't he just buy the iPhone 4S on her SERO plan now that Sprint carries it?
You're right, I just considered the $10 second line fee and not the additional data fee they probably charge.
