Hi guys!
I also suffer from the same problem, on october 22th, i enterd the 5th Avenue store in NY, asked for a no contract iphone 5 and confimed 10x times with the genius prior handing my credit card that i would like to use the phone with a generic sim card outside the US, he said sure just the price would be a retail price. i paid $749 + TAX and exit the store with a big smile on my face.
after leaving the US i realized that the phone is blocking me from sending text, from activating imessage and face time.
i called apple spent over 10 hours on the phone with over 20 apple employees, including senior advisors and technical support, some of them said i need to call sprint cause it's a sprint phone and only sprint can help, but sprint says that they cant help me cause im not a sprint member and i dont have an account nor a phone number in there system.
i have made all the known restores from DFU and from the phone itself, from itunes and from the clould.
nothing has made any change, the phone is still blocking my sms (texting messages)
I think i will not contact apple anymore cause im very tired already.
NO one on apple or sprint end seems to know what is the problem and they keep bouncing me like a pingpong ball from one another.
i have recoreded a senior apple advior from the 5th saying that my phone is unlocked and should be 100% fully functional, which is not.
in 2 weeks from now im going for a 5 days vaction to barcelona spain, i have no idea if they can assist me at the apple store over there, and im affried to take the phone with me for nothing.
i keep checking this post every few hours and hoping for all of us out there to end this nightmare ASAP.
best regards from israel.
Omer.
