Unlocking a Nokia 5310 can refer to either unlocking the SIM card (if the phone is locked to a specific carrier) or unlocking the screen/password. Here's how to handle each situation:
1. SIM Unlock (Carrier Unlock)
If your Nokia 5310 is locked to a specific carrier and you want to use it with another network:
Option 1: Contact Your Carrier
1. Check Eligibility: Ensure you meet the carrier's criteria for unlocking (e.g., completing the contract, full payment, etc.).
2. Request an Unlock Code: Contact your carrier’s customer support and ask for an unlock code.
3. Insert a New SIM Card: Replace the current SIM with one from a different carrier.
4. Enter the Unlock Code: When prompted, input the unlock code provided by your carrier.
Option 2: Use a Third-Party Service
- Search online for reliable third-party unlock services. Be cautious and choose a service with good reviews to avoid scams.
- Provide your phone's IMEI number (dial *#06# to display it).
- Pay for the service and follow their instructions to unlock your device.

2. Unlock Screen or Forgotten Password
If you’ve forgotten the screen lock (PIN, password, or security code):
Option 1: Default Security Code
- For older Nokia phones, the default security code is often 12345 . Try this if you haven't changed the code.
Option 2: Factory Reset
If the default code doesn’t work or you've set a custom code and forgotten it:
1. Turn Off the Phone: Power off the Nokia 5310.
2. Perform a Hard Reset:
- Hold down the Green Call Button , 3 Key , and * Key simultaneously.
- Press and hold the Power Button while keeping the other buttons pressed.
- Release all buttons when the phone vibrates or the reset screen appears.
3. Confirm Reset: Follow on-screen prompts to reset the device. Note that this will erase all data on the phone.
Option 3: Use Nokia PC Suite
- Connect your phone to a PC using a USB cable.
- Use Nokia PC Suite software to attempt a reset or recovery.
Important Notes
- Always back up your data before attempting any unlock or reset procedure.
- For carrier unlocking, some older 2G-only phones like the Nokia 5310 may not be supported by all networks due to changes in network standards.
