The Nokia 6301B is a simplistically designed phone released in 2008 for the T-Mobile network. If you purchase this phone, it comes with the software locked, which means that it prevents you from using a subscriber identity module (SIM) card from a different mobile carrier. If you wish to change to a different provider or use your phone while traveling abroad you will need to get it unlocked.
Instructions
1. Review T-Mobile's criteria for qualifying to get your Nokia 6301B unlocked for free. You must have purchased the phone from T-Mobile or another registered outlet for T-Mobile phones. The phone must be active for at least 90 days, and you must be using services offered by the T-Mobile network.
2. Dial "*#06#" on the phone to determine your Nokia 6301B's IMEI code. Wait for a second and a 15-digit code appears. Write it down.
3. Call T-Mobile customer support at 800-937-8997 and request a code from the customer service representative. Provide him with your IMEI number.
4. Buy an unlocking code online if you are not qualified for a free unlocking code from T-Mobile. Use the Unlocking, CellUnlockCode, or Foneszone websites (see Resources). You can purchase a code for around $20 as of 2010.
5. Input your email address, IMEI number, make and model of your cellphone and your payment information on the unlocking website of your choice.
6. Check your email account for the unlocking code sent to you. Save the code.
7. Purchase a new SIM card at a local mobile phone store for about $20. Open up the phone casing and take out the battery. Slide the SIM card out and replace it with the new one from a different network.
8. Turn on the phone and enter the unlocking codes when prompted to enter special codes. Click on "OK" and your phone is unlocked to work with a different network.
