Q: What is the Difference Between a Locked and Unlocked Cell Phone?

A locked cell phone is set up to work only on one carrier’s network. An unlocked cell phone can be linked to the person’s carrier of choice. Both work on GSM network carriers. GSM stands for Global System of Communication. You’ll need a SIM card from a GSM provider. CDMA stands for Code Division Multiple Access. Older phones using CDMA technology can’t be unlocked. If you’re buying a CDMA phone, make sure it is already unlocked.

Q: Why Buy an Unlocked Cell Phone?

You may live in a GSM area where you get a reliable signal from a carrier in some locations. But a different carrier has reliable service in other locations. With an unlocked phone, you can simply swap out SIM cards from different carriers in each network. You can also use the swap-out SIM card technique to keep work and personal use separate. That expensive cell phone of yours has much better resale value if it is unlocked. An unlocked cell phone doesn’t come preloaded with a bunch of extraneous apps. Unlocked devices are best for travel to a network out of the US. You can get a great deal on a used phone.
