can someone tell me how good is this company please?
What type of area do you live in?
I'm in a very rural area, and coverage is decent, here. Better than others. Everywhere else, it's wonderful. A bit slow, sometimes.
I've been to every state on the east coast with very minimal service disruption. A coverage map is available here.
East Tennessee it's great! Used it in Hawaii recently and perfect! Down in FL no issues
