Tom, thanks again for your help. Below is the "modinfo sierra" and "modinfo sierra_net" you requested. I hope it helps. I've had some more attempts to make it go. It is now being detected as a Sierra Wireless Aircard 320U, I'm wondering if the problem is really an incorrect description of the plan. Is it possible to get the modem to report back it's settings?

I know it's a Telstra 4G modem and the person I'm trying to help has given me their bill but no matter what I try calling it, it simply won't connect. I've scoured the Telstra website trying to ID the plan, but I'm just going in circles. I have a Telstra Next G modem I've never had an issue with, so I don't understand what I'm doing wrong.

I have learnt a few more commands when using the terminal, I suppose that's plus! Anyway, I hope you can help me, thank you for your time. Chris.
