Apple is full of crap. I just returned from

Brazil after spending a year there as a teaching fellow. When I tried to reconnect my iPhone 6 (only a year old) to my old carrier it wouldn't connect. When I went into apple they said this is a common issue and they can't do anything about. I was forced to buy a new phone even though my phone was in great working condition. If this has been an issue since 2013 you would think you would have found a solution by now.
