Most of the world's mobile phones work using Global System for Mobile Communications (GSM) technology. Mobile phones that use this technology use a subscriber identity module (SIM) card to identify themselves to a mobile network. For example, when you open an AT&T mobile account the sales person will give you a SIM card to insert in your phone. This let's AT&T know that particular phone is linked to your mobile account. SIM cards also have limited storage capacity. This is useful for storing contact files when you are switching phones.
Instructions
1. Insert the SIM card into your Windows Mobile phone. Remove the back cover and pry the phone battery out. Position the SIM card with gold contacts face down and the end with the missing notch facing the SIM card slot. Slide the SIM card into its slot until you feel it lock in. Replace the battery and battery cover on your Windows Mobile phone.
2. Turn on your Windows Mobile phone and allow it to finish booting up. Click "Contacts" to access your contact files.
3. Highlight the contact file you want to transfer to your SIM Card. Press the menu key to open the pop-up menu. Click "Save to SIM." The contact file is now on your SIM Card.
