I drive between Boston and NYC regularly. T-Mobile's service is pretty lackluster across the major highways in our area, especially 90, 84, and then Route 15.
Why is it that AT&T (and Verizon) can maintain 100% LTE across that entire trip, yet TMo drops down to HSPA or 2G. It's quite evident on Merrit Parkway.
Few weeks ago, I drove from NYC to Foxwoods by Mystic, CT. Once you get off 95 (towards Foxwoods), T-Mobile's service was basically non-existent until you get closer to the complex. AT&T/Verizon? LTE the entire way, even in the super rural areas.
Thanks. This is what I said it is not as good as Att. Thanks for Merrit Parkway. I use it more than 95 now. Last time I was on Att there, no problems at all.
Whatever route you get with Att here in the area it is LTE.
Yesterday I lost T-mobile on the top of the Tobbin bridge!

The day before yesterday I couldn't make a call near Prudential building.
Logan airport Terminal B is very bad.
Cape Cod was really was really bad, Now it is better.
I know T-mo is not as good, but it is enough for me. I'm usually in big cities and I'm covered. I tested my house again, our job spots, they are good.
I don't want to pay for 2 companies anylonger, so my choice is T-mobile.
The more important for me that I have fast speed internet in Toronto, Canada and great roaming in Europe. With Canada for me T-mobile has a better coverage. I switch mainly because of it.
I don't trust J.Legere's, he is too educated to behave like a next door man. The only lack in his education is a "street" education, I grew up in poverty on the street and he cannot "buy" me ;-). I don't know why people make a "God" from him. Are they going to prey him soon?

Anyway he is a wise guy, he is very wise guy.
Att gave me nothing for my roaming. In opposite as a payment for my loyalty they increased my price and stopped subsidy.
I always say , test it before you switch.
May I ask you, do you have LTE 12 phone with T-mobile?
P.S.
T-mobile in Lynn, MA is not usable at all. It was a pleasure to mesure speed on 2 iphones right in front of shelter at 8 pm.

I tried 4g , was not usable at all. I tweeted J.L. under the post with his VZW ball games.
It doesn't change anything for me, but this is how it is.
