How to Change Phone Numbers on SIM Cards

1. Contact your mobile service provider. When calling your provider, be sure to call them from a phone other than your mobile phone.

2. Advise your mobile service provider that you would like to change the mobile telephone for your SIM card. Also advise your mobile service provider the reason you desire to change your number, such as getting harassing telephone calls or you moved to a different state. Depending upon your mobile service provider and your reason for changing your number, you may or may not be assessed a fee.

3. Provide the mobile service provider with your SIM card number. You can locate your SIM card number by removing the cover plate from the back of your phone and removing the battery. Underneath the battery, you will see the SIM card. The SIM card number will be a long series of numbers that appear on your SIM card.

4. Wait while the mobile service provider changes your number. The representative may require you to turn off your mobile phone while the number is being changed and power it back on after the change has been completed.
