SIM cards, or Subscriber Identity Module, store information for your cellphone, including your phone number and mobile account information, contact list and text messages. BlackBerry smartphones allow you to easily insert SIM cards from another BlackBerry. Keeping your old SIM card means you can use your new phone with your existing phone number and transfer saved data from one phone to another. When you move your SIM card to a new BlackBerry, activating it is a very simple and fast process.

Remove the back covers and batteries from both BlackBerrys. From your old phone, gently pull out the SIM card, which rests under the battery. Insert the SIM card into the corresponding slot under the battery storage area of the new BlackBerry. Replace the battery and back cover.
Turn on the new BlackBerry. When a message appears on the screen prompting you to activate the new SIM card, press "OK" or "Continue." The phone will connect with your mobile network and automatically activate your SIM card.
Visit your mobile phone company's website if automatic activation fails. Many companies allow you to activate your SIM card online by entering your phone number and account verification information, such as your Postcode or the last four digits of your Social Security number.
Call your mobile provider if online activation fails, or visit one of its wireless stores. Ask a customer service representative to help you activate your SIM card.
Tips and warnings
- Not all mobile providers require SIM cards, so if your phone doesn't have one, call your service provider to activate a new phone. Mobile providers using the GSM network, such as AT&T; and T-Mobile, require SIM cards, but those using the CDMA network, such as Verizon and Sprint, don't require them.
