I currently live overseas and I signed up with Tmobile for free data in most countries. Two years ago, coverage was good enough to get emails, whats app and texts but lately I have been getting 4G in most places we visit - that being big metropolis types. Now, I can whats app video and google maps without any problem. Of course, wifi calling keeps you in touch but the data is the carrot on top.

Cant validate the States issues but the places I go. No problem. Have recommended Tmobile to new hires without fault.
