Tried wvdial with no additional luck. Devices seem to be pairing but I wonder if the error still lies there.
--> WvDial: Internet dialer version 1.56
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: AT&F
--> Sending: ATQ0
--> Re-Sending: AT&F
--> Modem not responding.
