In the US there are four major telecom companies Verizon, AT&T, Sprint, and T-Mobile. These four companies comprise the vast majority of all telecom users and most smaller companies contract out through them to use their infrastructure. T-Mobile was the first to provide the highest quality of service, 4G LTE, but they were quickly followed by Verizon and AT&T. The last major carrier to not offer 4G LTE was Sprint. Now all four of these carriers offer similar speeds and packages in most areas and much of the differences can only be felt outside of major urban areas.

Not only does each provider offer different quality of service but each carrier uses different signal “bands” meaning each booster will not necessarily be compatible with each carrier. Now to properly follow this you will need to know what kind of service you receive (2G, 3G, or 4G LTE) and what carrier provides your service. Don’t worry though it’s all pretty simple to figure out what booster works for you when you have all the information in front of you.
