I have been using an iphone 5 for the last little while and I just got the iphone SE. The only problem is my sim I ordered with the SE has not arrived (it's with a different network). I was wondering if I could set up the phone with the older sim and once my new sim arrives put that in it.
The iPhone SE is completely unlocked and I was just wondering if I put the first sim in if it would lock to that network.
