help for Lumia 640 on T-Mobile
My parents have been using their new 640s for a few days, but my dad discovered today that his office is a dead spot on Tmobile. His phone works outside, but not inside the building like his Sprint phone did. WiFi calling is not an option at his office, so they're looking at returning their phones. Are there any settings on the 640 or to do with Tmobile that may help his reception?
