Nighthawk MR5100 disconnected Telstra exhausted support

[Nath-Aus]

Sku is MR5100-1TLAUS

Device is unlocked, was working but somehow a voice sim was placed into the device, sim has since been removed and a brand new sim that was only activated todat as a data only sim is currently being used but still getting the "mobile broadband disconnected" message at start-up. Have been speaking to support at Telstra, they indicated that a request was submitted to netgear RE: unlocking however the return from netgear was that it is not locked. Telstra have now advised they have exhausted support from their end and that I need to contact netgear for further support. Firmware is NTGX55_12.04.12.00
APN is set at default. Any suggestions, what other information can I provide?

Ask the community they said...

About as responsive as the support. This was promised about a week ago

Netgear, never ever again. Don't skimp on the hardware especially when you rely on it. Cradlepoint for sure, at least the RFI LTE-XPOL-002 Mimo antrenna wont go to waste

Have you tried resetting to Factory Defaults?
