You do have a choice when it comes to the cellular provider for your Android device. Most of the time this decision is made by where you buy the phone: The store that provides mobile data also sells you the device. However, you can buy an unlocked phone, which can be used with any compatible cellular service.

The key issue when choosing a carrier is coverage. Though its colorful coverage maps may look good, the best way to ensure that a cellular provider has the coverage you need is to ask your friends and associates who use that same provider. Does the signal work everywhere? Is the signal consistent?

Another option available to you, though unpopular, is to pay full price upfront for the phone. Buying the phone outright frees you from a long term contract (generally, two years). Though expensive, using the service without a contract makes it easier to switch carriers if you later choose to do so.
