I figured out the problem. It's weird. The number I picked up is
existing account of a Virgin Mobile Customer. Yes! I still can call from
exact same number but when people call me back, they get to other
person. How it possible?
I switched to PM recently from Freedom Mobile and can compare coverage.
Now I have access to the network from my basement desk, but before no
service when I had horrible freedom mobile. I am so happy now.
