I'm using iPhone 4s with iOS 6.0.1
The problem is I can't send & recieve iMessage with my phone number. The activation always unsuccesful Using iMessage with Apple ID is OK.
The phone number displayed in "Phone" is correct (+84989892289)
I did many solutions which posted on this community but they didn't work (reset network settings, reset all settings, clear all data and settings, full restore firmware ...)
I used some my friend's simcards with my iPhone (4s) and they worked
I used my sim card on my friend's iPhones (4s, 4 or 3GS with many versions of iOS) and it didn't work
I asked my cellular provider to change another micro sim for me and it didn't work too
So the problem is about my phone number?
Please help me and sorry about my bad English.
Thanks so much
