We've been with At&t for 20 years. Ready to move to a larger data plan along with a hotspot. At&t gets spendy. In researching I see that Tmobile (which now includes Sprint) offers 50% discount for ages 55+. So for $10 less/month, we would go from 4Gb with At&t to 40Gb with Tmobile. Then they also offer a hotspot plan with 100Gb but it didn't list the price online that I could find so have to check on that.

Looking at coverage maps, they certainly look comparable. MobileInternetResource speaks highly of their offer, but not specifically about how reliable the coverage is. So thought I'd just check here if anyone can comment on their experience with Tmobile since taking on Sprint and the added coverage?
