Important advice! Please read carefully!
Before you order a Samsung J640 unlock code, make sure you follow our requirements checklist:
1. You have to be certain that your phone is network locked. Try to insert a SIM from a different network and wait for the phone to ask for the unlock. If it doesn't prompt for the code, and you can make a regular call, than your phone is NOT SIM locked.
2. Be certain that your phone is NOT stolen or blacklisted.
3. Be certain that your phone is NOT hard locked. If you tried too many times to unlock it before, your handset may be locked forever.
4. Make sure to give us the correct IMEI and to select the original country and network, NOT the one you want to use.
We will NOT be able to refund your money if our service fails to unlock your device for any of the reasons mentioned before.
