Place for very accurate cell service coverage maps?

[Aston01]

I live in an area that according to all the cell phone coverage maps has 100% coverage, but everyone with T-mobile has issues when they come to my house (even outside). After looking at coverage maps from a lot of different places it has me curious if everyone is using the same data and formatting it different and more importantly if there is actually somewhere I can look at an accurate coverage map for the different services.

 

Any suggestions?

opensignal is a quite good representation of local speed: (mobile only)
