Samsung Carrier Relock

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


MCC/MNC World List
This is a complete list of all carriers in the World, with their country (MCC) and network (MNC) identifiers
You select from here, maximum 64 items

Carrier templates
Here you can choose predefined carrier lists, grouped per country/region
You can also create and save your custom lists, they will be here too

Set as Default
Make the selected list the default
Any time you open the procedure window, it will be selected so you just have to click Start

You can delete your own, customized lists. Chimera predefined lists cannot be deleted

Clear all items in the “Selected for Relock” list

See how many items you added in the list, of the maximum 64


Use these arrows to move items between the two lists
How can I select the carriers
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

How does this work
Usually, manufacturers use two levels to control network access

There is a global flag what defines the phones network access, independently from the carriers:
it can be locked, temporary unlocked and permanently unlocked
The permanently unlocked devices will work with every SIM card

And there is a carrier control list (MCC/MNC pairs) what contains a list who can access the network
so their SIM cards will work in the device

Our “Carrier Relock” procedure is based on the second method

For example
Let’s say you have a device locked on T-Mobile USA (or MetroPCS or Verizon

You want to use another carrier’s SIM card in this device

But there is no unlock solution for T-Mobile, MetroPCS and Verzion at the moment

So with this new procedure you can network lock your device to any other, different carriers (maximum 64)

As a result, your T-Mobile locked device will accept SIM cards from all the other carriers that you selected

Basically if you lock it to all carriers in your region/country it will accept all SIM cards from your region/country
