Will a Virgin Mobile sim card work in a Sidekick 3 phone ?

I have a Virgin Mobile Lg Rumor Touch 2 phone and I was wondering if I put my sim card in a Sidekick 3 phone will it work . Thank you for your help .

Hi yes you can use your old virgin sim in sidekick 3 only if it is unlocked one ..Else if the phone is locked to some other network provider then until you unlock it you can't use it with your old sim ..You can easily unlock your sidekick 3 mobile using sites like MobileUnlockSolutions.com here they are rendering unlock code for all mobile models at reliable cost ...After unlocking your phone you can freely use it with any GSM sim ....
