Here’s a closer look at unlocking a Samsung cell phone from Rogers. It’s a fairly straight forward process that starts with inserting a sim card from a network other than Rogers (i.e. Telus, Bell, AT&T, etc).
When we then start up the phone and swipe at the home screen a dialogue comes up asking us for a network unlock code. After entering the unlock code the cell is then unlocked and can be used on most networks worldwide.
