If you wish to get a SIM unlock code for you Storm you need to meet some qualifications first. Your line of service must be active for at least 60days, and during those 60days you must be in good standing. No past due payments or suspends/disconnects due to non-payment. Finally, the device to be unlocked must currently be active on VZW service.
If you meet these qualifications a SIM unlock code will be provided to you free of charge by contacting the Global Support team at: 800-711-8300
