cell tower connection

@ah7630 short answer is a hard no.

There are exactly two possible charges, $14.99 per month and $24.99 per month (ok, 4 possible, since some states charge sales tax).  

As for SS experts, there are the ones on the phones (allegedly with varying degrees of competence, although I've never had any problems with them), and the ones here on the forum.  Call them or if that doesn't work for you, post your question(s) in the forum, with useful topic headers.

A quick search found this company.  I don't know anything about them, but it might be a start for you.
