I'm trying to find out what cell company this cell phones from? If anybody has any idea please let me know? I have a fido SIM card and it fits into the Samsung but has that lock icon on it.
The following sim-unlock procedure works for the Samsung Galaxy S4 (GT-9505 Model):
This will take you to the following screen 2. Press Menu button then tap "BACK"
The Galaxy S4 will freeze, black screen, Blue LED Light, Menu and Back key ON. Wait for it to reboot (takes about a minute). Afterwards your device should be sim-unlocked.
