Compared to contract cell phones, most mobile users prefer unlocked cell phones due to the limitation of the locked devices. But what is a phone lock and what are the differences between a locked and unlocked cell phone? In this article we will explain to you as well as provide you with 10 Amazon best sellers unlock cell phones.
The lock is really a software code that's put on the phone by the manufacturer as per the requirement of the carrier that sells the device. And the lock is meant to ensure that the phone can't be used on any other operator's network until a different software code is entered to unlock the device.
An unlocked phone is a device that is not bound to any carrier or plan. It allows you to choose your phone first and your carrier second. Upon selecting a plan, simply insert the carrier's SIM card into the phone and you're ready to go. If you decide you want to change carriers down the road or want to take an international trip, it's as simple as replacing your existing SIM card with a new SIM and activating your new plan.
Freedom: Choose the carrier with the best service or price. If you find a better deal later, you have the ability to change to a different carrier.
Travel: Take your phone internationally and use the carrier of your choice. It's as easy as inserting an active SIM card.
Selection: Choose the phone with the features you want, whether or not your carrier sells it, and get more service options without a contract.
