How the unlock works
A device bought on T-Mobile in Austria stays tied to that carrier until the contract or instalment plan is settled. The carrier holds the lock in their database; once the record is cleared, the phone accepts any SIM.
This service clears the lock server-side using NCK / MCK / SIM unlock code. Nothing is flashed, nothing is opened, and the device keeps its warranty. You only need the IMEI.
- Confirm the Samsung is locked to T-Mobile (any carrier check service).
- Order service #440 and submit the IMEI.
- Wait for delivery — usually 1-5 business days.
- Enter the NCK code when the phone asks for a network unlock code (MCK clears the second lock level).
