I don't know if it is a secret. We use T-Mobile. I am connected most of the time as I travel. I use cellular one for my mobile phone and have noticed I often do not have as strong a signal with Cellular One.

Sometimes the connection with T-Mobile will waiver while I am faxing but the system we have just picks up where it left off when the signal is strong again.

I received your post as I was traveling just now. I have a little time to kill as the next county is closed for lunch. So I pulled off to the side of the road to reply. Now I'm back going to head on down the road.
