Things You'll Need
Here's How to Unlock Virgin Mobile Phones
Gather the information you will need to unlock your Virgin Mobile phone. You will need to know your mobile phone number, the manufacturer and model number for your phone, the network and country your phone is locked to and your phone's IMEI number. The IMEI number is a 15-digit number you can find by entering "*#06#" on your phone's keypad.
Call Virgin Mobile and let them know you want to switch to another cell service provider. You may be required to give a one-month notice or pay a fee in exchange for the Virgin Mobile unlock code for your phone.
Use an online unlocking service like Unique Phones to obtain the Virgin Mobile unlock code for your phone (see link in Resources). Unique Phones offers unlock codes for many different phone models for less than $5.
How to Program Virgin Mobile Phones
Turn on your Virgin Mobile cell phone by pressing and holding the "Power" button. Use the keypad to enter the code "##VIRGIN#" or "#-#-8-4-7-4-4-6-#." This code takes you to the Programming menu of your cell phone. Note that some models of Virgin Mobile phones will require a different code such as "##VIRGIN" or "#-#-8-4-7-4-4-6."
Scroll down to "Activate Phone" and select "OK." A message will appear asking, "Do you want to activate your phone now?" Choose "Yes." Press "Start," followed by "OK" when you see the message, "Hi. Press Start to continue the activation process."
Wait for your phone to display the message "We're getting your phone number for you." Write down your 10-digit Virgin Mobile number. Click Finished > OK to complete the programming process. Your Virgin Mobile cell phone will turn off and on all by itself.Source: ehow.com
