About 3 months ago, I lost the ability to make a phone call from my house in Westminster. There was no signal. The signal came back strong yesterday. 4 bars on the antenna from inside the house. I did not check for 4g signal, but will check tonight. Also, today at work in Hunt Valley/ Cockeysille, the 4g signal is on. Is it strange that the server is listed as Reston, Va?
