Delivery Time: 1 - 12 HRS.
Will receive ALL level codes,
This service will take 1-3h only on working hours :1am-6pm EST Monday to Saturday
All Samsung models supported locked to any GSM USA network
The phones from CDMA networks like Sprint or Verizon ( normally have imei starting with 9xx ) will not ask for unlock code,so are not supported !
There is no refund if the code is not working for T-Mobile/MetroPCS phones that were made to be unlocked by the Device Unlock app.
There is no refund if we deliver the code but you can not use it because the phone is not asking for unlock code with a sim from a different carrier!
-First, try the Network code (or SUBPROVIDER code if asks for service provider code ) when the phone asks for unlock code with a different SIM, and if not working, factory reset it, insert the Defreeze code (will not be accepted but is OK) and after the Nck code and should work
It is possible for the imei to be rejected not found. In this case, we will refund.
