Perfect alternative for expensive NBN or as a backup Internet connection.
Those modems are best suited while connected to Routers or other NBN Modems as a backup. They can be also used while directly connected to a Windows PC, but will require a driver (will be provided after purchase).
Tested on many devices using SIMs from Telstra, Optus, Vodafone and ZettaNet on following Devices:
Draytek Vigor 2820, 2830 and 2850
Draytek Vigor 2760 series (tested in DHCP and PPP modes)
Draytek Vigor 2762 series (tested in DHCP and PPP modes)
Will test with more devices during next few days.
If you are unsure if your Device will work this those modems, please let me know what you have and I will test it.
