Telstra Smart Modem for home phone

Hi there,

 

I'm about to go onto the Telstra 5G network for our home internet etc. Consequently, we won't have a home phone. I wouldn't mind having one just as an emergency (old parents ringing etc). Can I use my Telstra Smart Modem (that's leftover) to plug in our cordless and use as a 4G network? Would I have to change the existing SIM card that's in there? Will a Panasonic 6.0 DECT cordless work? Thanks in advance. 

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

That wouldn't work as there wouldn't be a phone service for it to connect to. You would need to get a separate NBN based Voice service from Telstra for the Smart Modem to have an account to connect to.

 

The 5G Home Internet service doesn't come with a phone service.

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

Thanks for that Jupiter. Excuse my lack of knowledge - but could I run the Telstra Smart modem separately to the 5G network with a 4G (prepaid) sim in it and run a phone off that? Or is it just not built for that?

No. If you use the smart modem with a normal SIM you will have internet but no phone. What you can do is sign up with a VOIP servic provider such as vonex and either get voip adapter that plugs into a lan port of the 5G modem,, a voip phone or install a voip app on your phone. Your current phone number can be transferred to the VOIP service.

Not with the Smart Modem 2, but there are other 4G Modems out there that can use a Voice/Data SIM (haven't tried a prepaid or voice only SIM though, but they should work as long as the device is unlocked - ex Optus devices are unlocked), to provide a connection point for a corded phone handset or cordless handset/base station. Huawei E5186 and B525's do that and are quite cheap on the second hand market. I have installed them for several caravanners where they are a good solution for those needs, but they will work anywhere. I will have to try a voice only SIM in it
