Use our “Carrier Relock” procedure to unlock devices by relocking them to any (max) 64 selected carriers.
If you unlock a phone’s network lock (SIM-LOCK), then it will work with every mobile carrier, this is a well-known method. But what happens if you locked the device to all carriers? Well, it would accept all SIM cards, from all mobile operators. We don’t have the solution to lock for all, but you can select 64! This can cover countries and regions so the device will accept all SIM cards by the carriers you choose. After the successful “Carrier Relock” procedure, your phone will be relocked to the selected carriers (max 64) so it will accept all SIM cards by all those operators, just like it was unlocked!
Just simply select any carrier in the “World List”, then click the right arrow (or double click) to add it to the “Selected for Relock” list. When you start the procedure, the device will be relocked to all carriers listed in the “Selected for Relock” list. You can save your customs lists so you don’t have to go through the selection process every time in the future.
Usually, manufacturers use two levels to control network access:
Our “Carrier Relock” procedure is based on the second method.
What if you got a SIM card which is unknown for you,in other words you do not know what is the card's MCC/MNC code:
NOTE: Sim card must match to providers from relock list!
[You can change from TMB (T-Mobile) and TMK (Metro PCS) networks to other networks]
Please don't attempt the Permanent Unlock in settings, or the relock operation will be reset to default.
