I've had a different experience with the WiFi CampPro V2. It has worked well for us, making it relatively easy to share WiFi, occasionally at campgrounds but more typically at places like McDonalds, Lowes, etc. Never had any problems with it at home either, always worked fine when we tested it.
I said WiFi Camp Pro v2 worked, but if it had worked relatively easy, I would have kept. Yes, you can connect to McDonalds, Lowes and similar but you had to pull outthe laptop to configure the settings each time. It could take 15 - 20 minutes but very up and down. Then when trying at most RV Campsites if you did make a connection the bandwidth from the host services was so poor you could only do email anyway. I put it the category of those that like RV covers, yes they work, but there is a reason why WBGO manual says they do not recommend.
In our case, we connect the CampPro to the network in question, and we just set up the various devices (tablets, laptops, etc.) to connect to the CampPro's SSID and no further configuration or reconfiguration is required.
For the CampPro v2 what I refer to above requires a laptop to configure the router to the new SSID you wish to use. One that configuration was complete yes all subsequent device devices could connect with no further configuration. Once connected I would say 70% of the time we did not have enough bandwidth to stream. About the only place I could say we could stream youtube TV was when we were at a Wal mart. I work from home and sometimes the RV and being able to stream Teams or Google meet is essential. The latter was NOT Wifi Camp Pro's fault, but it was hassle to setup and configure just to find out. I would not recommend to my worst enemy (if I had one)
We recently signed up for T-Mobile 5G wireless internet at home. Don't know if that's the same service you are referring to or not. Ours is the current offering ranging from $50 to $65 a month, depending on if you have discounts for T-Mobile cell service and auto-pay (which requires giving them your bank account or debit card number).
It is same T Mobile Home Internet. When it first came out I was paying $50/month. After a year I got a new plan that is $30/month and now $25/mo with autopay. I gave them my bank account number. I know some don't care too, but I figured out a long time ago, there is no such thing as privacy anymore. That is why we get mail every day from somebody telling us how much they value our privacy.
I have had good results at home with the T-Mobile service, but the terms of service specifically prohibit moving the gateway elsewhere (other than the service address) which precludes taking it on the road in our RV. A shame as that would be a really nice option when traveling.
Yes that is what they say, I talked with T Mobile Support and was told that while the devices have GPS, they primarily only use to track those that setup at a residence in area not supported. They said it might take 2 or 3 months of usage in unauthorized area before getting flagged. That was years ago. I know know T Mobile markets a plan just for RVs. In my view, I follow policy. My T Mobile Home internet is always on inside my RV that is 90% of the time at my Home address. When I get in my RV and drive to Florida to I take it out first? No. Typical trip for us is 3 - 5 days, we have streamed 200GB in one trip and no issues. No antenna to fool with either. We keep device on a shelf. We even stream TV while driving say Dallas to Houston and zero disconnections. I know T Mobile is not everywhere, so it is not for everyone, but I guess that is not a focus for where we travel.
On the emergency communications front...
We are often in very remote areas with no WiFi or cell signal. We looked at satellite phones, but they are expensive to buy and the plans are also pretty expensive. We decided to try a Zoleo satellite communicator as an emergency device, giving us the ability to send texts and short e-mails, along with location data and SOS capabilities for a reasonable monthly fee. We can also pull weather reports. So far so good. I'd certainly prefer a satellite phone and perhaps that's the next step, but the Zoleo is a useful option at a reasonable price.
