I wonder if the coverage folks now this, but :-
a) 4G LTE Coverage Map | Check Your 4G LTE Cell Phone Coverage | T-Mobile is not working, The "Oracle server ..."
b) I have tried twice, using T Mobile SiM cards in my home and even outside my home, and there is no service for T Mobile. My relatives who use T Mobile, got into 'smartphone deprivation shock' when they stayed at my home.
ATT is what I am using currently, and I would really prefer using T Mobile as ATT's international roaming plans is 'extortion'.
I am hoping that TMobile coverage folks see this post. I tried to twitter to @TMobile but to no avail.

I did check that zip code. The coverage there does vary, so depending on your exact address, I'm seeing the coverage would be stronger outdoors. I do understand that the coverage map may not be exactly what you're getting on your phone and I feel bad it's been like this for so long. As I mentioned above, the best way to bring some attention to your address for coverage improvements would be to have a Care expert to file that Service Complaint. For example, anyone who visits you that has T-Mobile service and is having trouble in your area can reach out to our tech team. I can't promise the Service Complaint will give immediate results, but it does help bring awareness to our field techs about what kind of service you're getting.
