Buying a phone can be tricky and there so many things to consider, especially whether or not the phone is fully-unlocked, or locked to a specific carrier. And if you really do your research, you'll find that some carriers (MVNOs) can work with phones that are locked to another carrier — for example, Metro customers are able to use some devices that are locked to T-Mobile, since it uses the same network.

Locked vs. unlocked
The main difference is that with a locked phone, it's linked to a specific carrier and has a software-level lock on the device (often called firmware), which prevents the user from using the phone with another carrier. A fully-unlocked phone doesn't have this firmware, and in most cases, all you need to do to get started is insert your SIM card.
Fully-unlocked phones can be used with virtually any carrier, in the US and internationally. However, before purchasing a device, we encourage you to check the compatibility of your data plan with your carrier to ensure that it will work with the device.
