Coverage in Mccook..

Is there now coverage in Mccook, NE?

A couple of months ago my daughter's service was discontinued by T-Mobile due to too much roaming. This was after an agent informed me that there was good coverage in her area. Because of this information I purchased an upgraded cellular. Shortly after the purchasing of this new cellphone, I was informed that my daughter's service would be discontinued because of roaming.

As you can see from the coverage map below, it shows that there is 5G service in the area. It is very misleading.
