thats why I never switched to that mobile share crap. unlimited for life.
I used to think that as well, until they throttle me after 5GB. Download movie for half a day. Became a real pain.
When they offered me the share plan last February I looked at the numbers. Saved me $100 a month and declared my 5s paid in full, and was mine. Then I could get next phone for two year contract but monthly rate would go back up on both phones. Or bring my own phone, i.e. Pay full price for phone and rate stays same. Or use next option, rate stays same, but tack on monthly phone payment no interest. Better deal than old way where I paid $200 up front and higher rate for ever. Now they front me total cost of phone minus taxes.
