I have the next level up with LCD screen. They are marked at $79 but show as out of stock. I note theer are a few on ebay. I have not looked to see what the differences are.
The downside with Telstra modems is that they are locked to Telstra. Unlocking will cost more than the modem - $80. Reduces to $25 after 6 months, Free after 2 years. Other telcos also have modems, but I am not familiar with them.
There are more expensive options, or you could just use your phone as a hotspot.
RV wifi is an expensive old technology, then you have the comparison between the Telstra 4GX wifi hotspot made by ZTE and a few others and the Nighthawk 5G hotspot made by Netgear, the Nighthawk is the better unit but they are expensive.
The down side is these all required a Sim card and a data plan, unless you can get a data share Sim card from your service provider, the Telstra 4GX is available from supermarkets like Coles for $49, but remember they are in real terms old technology.
An example of how this can be done, I have a Telstra mobile on a plan, I added a data share Sim to my account, which cost $10 per month and adds 10gb to my data plan, my wife has a 12 month prepaid Boost mobile plan with 240gb of data.
We have a Telstra 4GX hotspot, initially the data Sim was placed in it, to give internet access to all our devices like phones, tablets, laptops, TV's and even our air conditioner, I set the limit of how many devices can connect to the hotspot. After a while I found the Telstra hotspot was lacking in performance, I upgraded my mobile phone and then used the old 5G phone as the hotspot, which improved the performance.
