Get a new SIM card for your O2 BlackBerry so that you can use it while traveling.
O2 is one of the largest mobile phone carriers in the United Kingdom. If you purchased your BlackBerry smartphone through them, then it is likely locked. This means that you will not be able to use the phone outside of the country without incurring expensive roaming charges. In order to avoid these fees, you need to unlock the phone.
Instructions
1. Dial "*#06#" into your phone. This will bring up your serial number, also known as your IMEI.
2. Write down the 15 digits that you see, and save it for later. You will need this to create your unlock code.
3. Look for a site that sells unlock codes for the BlackBerry on the O2 network (see Resources). As of 2010, a code can be purchased for about $25.
4. Go to the site, and enter your IMEI number.
5. Choose the "O2" network as your service provider, select "BlackBerry" as your phone manufacturer and pick "8100" as the model.
6. Submit your payment information, and a code will be emailed to you.
7. Turn your phone off and remove the SIM (subscriber identity module) card.
8. Insert a new SIM card from a different network, and turn the phone back on. You will see a message that asks you to enter a special code.
9. Enter your unlock code exactly as you see it in your email, and press "OK."
10. Wait for a few seconds, and your BlackBerry will restart. When it comes back on, the name of the new network will be at the top of the screen.
