Joe is having trouble with his ZTE Z988 phone and hotspotting. He keeps turning it on and after a minute, it drops. Leo says to call T-Mobile and let them know his hotspot feature isn't working, because it sounds like they haven't activated it. But it's also possible that it's not available with that phone and his new carrier. There can be some hardware limitations too. But if he's getting data anyway, then that's not it. It probably just needs activation.
