Is Your Samsung Phone Network Locked?
Before visiting a repair shop or purchasing an unlock service, it is important to verify whether your Samsung Galaxy phone is actually network locked. In 2026, several quick methods let you check SIM lock status on any Samsung Galaxy device in minutes.
Method 1 — Insert a Different SIM Card
The simplest and most reliable test:
- Get a SIM card from a different carrier than the one your phone uses
- Power off Samsung phone
- Insert the different carrier SIM card
- Power on the phone
- If phone shows signal and works normally → phone is UNLOCKED
- If phone shows "SIM Not Supported," "Enter Network Lock Code," or "Invalid SIM" → phone is LOCKED
Method 2 — Samsung Secret Code
- Open Phone Dialer on Samsung
- Dial *#7465625#
- Samsung Lock Status screen appears
- Check Network Lock status — shows Disabled (unlocked) or Enabled (locked)
- This shows lock status without needing a second SIM
Method 3 — Settings Network Information
- Go to Settings → Connections → Mobile Networks
- Check if Network Operators option is greyed out
- If you can see and select different networks → likely unlocked
- If only one carrier is shown and cannot be changed → likely locked
Method 4 — Samsung IMEI Check
- Dial *#06# to get your IMEI
- Visit samsung.com/us/support/mobile-device-support/
- Enter IMEI to check carrier lock status
- Samsung official tool shows if device is unlocked
