Mike n Sue,
No Morons, just folks who don't either have the time, or inclination to learn the details, I get it!
So, my wife and I started our RV adventure not long ago. Because I worked in Information Security for 20 years, my wife expected that I would make everything work just like at home..... Yeah, not so much.
I have come to a couple of conclusions FWIW.
1) If you just want to get email, go online for brief periods, maybe chat with the grandkids once a week, AND you are staying in mostly urban settings, I believe that using a smartphone as a mobile hotspot, is likely the easiest answer. Providing your service has the feature, and your plan allows for the data you will consume, I do not see anything else remotely close.
2) If you are a tech Nomad, using Internet everywhere you go, streaming online courses and games, blogging, putting up YouTubes, etc. Well, this is whole different story, and there are entire sites devoted to that. You are likely then into multi-sim routers, YAGI antennae, etc.
3) If you are somewhere in the middle (I seem to be there), maybe streaming Netflix for an hour or two, being on the computer for an hour or two a day, having multiple smart devices in your travel vehicle, then I think I have found a potential solution, however, YMMV.
For me, I went and bought a travel router. I bought one off of AliExpress (yeah I know China and all that, well guess what most of our tech is already made there) for less than $100.
This is a completely unlocked device, similar to a MiFI from Verizon capable of using any SIM card (completely unlocked), so that means searching for a DATA Only deal that worked for me. The boss and I use GOOGLE FI as our smart phone carrier, and they allow me a data only SIM to use in my router. (I am connected using it now, and it supports up to 15 devices)
I added an extended antenna for about $15, and may add a directional antenna on a pole later. However for the moment, I can access the Internet, stream Netflix (I expect to be able to use my Kindle FireTV stick also) and make Internet based phone calls and use the data service on our smartphones. SO for me this covers it all for the moment.
I know there are lots of solutions out there. I was in Camping World here in Florida the other day, and they have a cell booster for $500. OMG!
My point, in closing is that with a little research effort, you can find a low cost solution that works, very well. Best of luck, let us know what your final decision is.
