Jeez, they sure do make this confusing. Youd think if they support LTE then they would be compatible but..
"LTE, or Long Term Evolution, is the globally accepted 4G wireless standard. All of the US carriers use it. For more, see
3G vs. 4G: What's the Difference?
And all of the carriers use the same 5G standard. (For more on that, see our
explainer on 5G.) So you'd think, hey, that should make everyone compatible, right? Wrong.
To be compatible, you need three things:
- To be using the same technology, like speaking the same language
- To support the same frequency bands—being able to tune to the right channel
- To be allowed on the network"
