How to Unlock a Siemens Mobile Phone

The Process
1. Remove the battery cover from your Siemens phone. With most Siemens models the Subscriber Identity Module (SIM) card is located behind the battery. Remove the battery from the phone.
2. Locate the SIM and use you forefingers to pinch the card. Be gentle or you might damage it. Never touch the gold contacts. Remove the SIM by pulling it back and out.
3. Replace the battery and back cover. Turn on your phone. It is very important that there is no SIM card in the slot at this point.
4. Insert your unlock code. You can either pay for this code or search the Internet for a crack generator or an individual who distributes the codes on a free website. Try uniquephones.com.
5. Once you have your unlocking code, type it in. Your phone will automatically restart, taking about 15 seconds.
6. Congratulations, your phone is unlocked. Test the phone by inserting a SIM from an alternative carrier and see if you can make calls. Usually you will have no problems, but some carriers try to keep you from doing this by creating phones that are proprietary. You can buy unlocked phones, but they are expensive.
