I am a new Sprint 4S customer. I was just told that to activate international features I would need to physically go to a Sprint Store and show two forms of ID. No matter how much I protested, they would not budge. I was in a store a week ago to buy my phone. At the moment I have no time to go out to a store and fix this before I need to leave on my trip (11am tomorrow) I even asked them to send me to customer retentions and they saw my bluff. I called the store I bought the phone from, spoke to the guy who sold the phone to me. He remembered me (it took a while to order and we talked about cars and stuff), so basically could vouch that I am not fraudulent, but said there was nothing he could do to turn this feature on my account. I bought this phone because it is a world phone, and now Sprint does not want to turn on my SIM for International roaming. I will attempt to buy local prepaid when I get where I am going, but if the SIM slot finds it's self locked, I will be returning my phone within it's 14 day window without a doubt. I thought Sprint was supposed to be better about customer service.
