Bigpond settings MR6110 — Nighthawk M6 Mobile Router for Telstra Model / Version: MR6110-1TLAUS

Hi All,

I sort of leapt before looking.
I have a Telstra bigpond plan I wish to keep and my old Netgear Aircard AC790S will eventually be outdated.
I bought a MR6110 — Nighthawk M6 Mobile Router for Telstra
Model / Version: MR6110-1TLAUS through Telstra and they said they will send a sim.
They didn’t send a sim and said I need to get one of their new plan as the previous plan/sim is not compatible with the new device.
I’m under the impression the MR6110 — Nighthawk M6 Mobile Router for Telstra
Model / Version: MR6110-1TLAUS is unlocked.
I have cut my SIM card and the new device shows it is reading my sim however I can’t get online.
My question is are there APN settings and authentication settings ext… that will get my new device connected.
I still can put my sim in the air card device and have tried to match settings back and forward.
Thankyou in advance
