Unlocked Cell Phones Explained

Most phones are tethered to one service provider. This is why people have to purchase new phones when switching to a new company. Also, when traveling to a different country, the phone also won’t work since it’s trying to use another company’s cell phone service. In both cases the phone is locked.

Depending on the type of phone and cell phone company, it can be possible to unlock the phone. Then, switching to a different company, changing phone numbers, and service accounts is much simpler.

The two cellular phone technologies that are being used today are Global System for Mobile (GSM) and Code Division Multiple Access (CDMA). GSM cell phones are usually the ones you find when looking for unlocked cell phones. GSM phones use SIM cards, a small card inserted, into the back of the phone that is linked to a cell phone account and contains contacts and other information. It’s possible to take the SIM card out of the phone and put it into another phone (that is unlocked). Then if someone calls the number, the new phone, with the SIM card, will ring.

Some more advanced codes have a code tying a particular phone to the SIM card. In these cases, individuals may need to enter the code into the new phone to unlock it. Some service providers will provide the code for a fee. In some cases, the phone has to be connected to a special device to unlock it. While not many service providers will do this, phone owners can send them to a third party who will unlock the phone and send it back.

Unlocking a phone is fairly simple and inexpensive. It’s a great idea for frequent travelers who go outside the country. Unlocking a GSM phone is almost always possible and many times it can be unlocked for a small price. However purchasing a cell phone that is already unlocked would be the best choice, especially if you know you will be needing unlocked cell phones.
