Some mobile service providers, such as AT&T, Verizon, and T-Mobile, may provide bundled packages that include a cell phone and a prepaid or postpaid connection. In this situation, the company offers the smartphone for a reduced price. And if a provider offers the bundled connection, they impose various hardware and software restrictions on the smartphone.

The handset is said to be “locked” to the service provider’s SIM card. Unless the phone is SIM-unlocked, no other SIM card will work with it.
