Looks like you used the pppd option default-asyncmap, not a good idea
unless the peer does the same. The pppd implementation default is
0x0 whereas default-asyncmap causes pppd to require the peer use the
PPP default, i.e., escaping all control characters.

The peer drops the <asyncmap 0x0> but that may not be meaningful.
See below.

The peer rejects all CCP so adding the pppd option noccp would be
in order.

The peer refuses VJ compression so adding the pppd option novj would
be in order.

This is consistent with a wireless phone Internet connection. The PPP
implementations of those are very often of rather poor quality. I'd try
removing the pppd default-asyncmap option. I've no other ideas.
