I got a hotspot just for this and have used it successfully in 10-15 countries in the past 9 months. Sprint still doesn't have LTE where I live, so rather than paying for the T-Mobile hotspot for use abroad plus the Sprint bill for absurdly slow data domestically, I'm going to ditch Sprint after 15 years and just go with T-Mobile for everything. I don't even do anything data intensive domestically, but Sprint is years behind T-Mobile's LTE deployment. Yes, I know T-Mobile doesn't have great coverage in places I'll never be.
