1) Confirm that you phone is now factory unlocked. Call your service provider or phone manufacturer and ask them to check or just go ahead and factory unlock your phone. It can be done remotely, over the phone. You will likey need your phones serial number and other details so have that ready. DO not tell them you are moving, just say you are travelling for a month or so and need to have it unlocked.
