People are often confused about whether their iPhones are Factory Unlocked or Locked to a specific carrier. When you are about to buy a new iPhone or second-hand one, you must be aware of the IMEI status of the iPhone.
I know there is a lot of new vocabulary; Factory Unlock, Locked, IMEI... but by the end of this article you will gather a clear idea about this.
