I never checked T-Mobiles coverage map myself. I used to have AT&T and their coverage map clearly showed a small area a block north of me that had no coverage. It was accurate but it should have extended another block south to include my block. I could never get 3G or LTE service here and Verizon was the same way. It was always like a dead area.
I only tried T-Mobile about four years ago when they first announced that they would be officially supporting the iPhone beginning with the 3GS. I was finally able to get 3G back then and then LTE a bit later and from then on, it's only gotten better. I would never think of leaving T-Mobile now.
There still is a small area west of me that has no coverage but I've noticed it's gotten a lot smaller over this last year.
I still can't depend on it for Google Maps or other over the air type GPS apps during congested times but it beats AT&T and Verizon for me.
