If you're like me and switch devices a lot, you may find yourself losing contacts in your address book from time to time. This doesn't happen as much as it used to thanks to the many sync options on BlackBerry however. If you want to be sure you carry your contacts along when you switch devices, simply save them to your SIM card and they'll always be with you. Unfortunately there is no decent way to copy all of your contacts over to your SIM at once, so you'll have to do it one by one for each contact. The process is super easy and will only take you a few clicks, so keep reading and see how to make it happen!
Keep in mind that older CDMA devices that don't use a SIM card won't be able to do any of this.
That's it! Your contacts are now safe and sound on your SIM card. Just remember that if you for some reason switch SIMs, your contacts will stay with the old one. Thankfully, copying contacts back from your SIM to your address book is much easier as it lets you copy them all at once.
