Might it be wise to disclose the 'Home Phone Adapter" is not an LTE device and requires wired ethernet connection…
Seems like it a massive overlook to fail to mention the requirement for the Grandstream HT801 to be hooked up to an EXISTING wired ethernet connection.
Initially I assumed the device was an LTE ethernet modem such as Netgear offers.
Thought it might be the followup on the “Republic Wireless Data Sim” trial of last year.
Some of us in rural areas (or is it just me) get our Internet connectivity via a tethered connection to Republic Wireless.
A little clarification might be in order.
