Turns out you can get a 5G phone with unlimited internet data for $60/month.
This seems to be a promo while 5G is just getting started.
I just ordered a Samsung A71 5G on Amazon (refurbished) for $329. Which is a $130 premium for the 5G band and the Samsung 11 OS, but the other reason I bought it was for the 64MB camera; and it has more on-board memory vs. the A52.
The next jump in cell phone performance will cost you $500-$800, but I think this A71 will last me 5+ years or more if I don't lose it or break it.
These phones can also be used as hot spots but they only work if you are able to pick up a local 4G-LTE or 5G Tower; and I bought it "UNLOCKED" so I can go with Ting.com at $10/mo plus $5/1GB of data.
I went with Ting, because I don't use much data when I'm not traveling, so I would prefer to pay as you go. However, if you are streaming monster then the unlimited, and unthrottled $60/mo plans maybe for you... while they are offering them from AT&T and others.
Also, I am finding GSM is the dominate type of cell phone from T-mobile and AT&T; so I'm moving away from CDMA tower connections typically offerred by Verizon or one of the secondary carriers.
And all these "unlocked" phones are supposed to work in international countries so that means I should be able to by a sim card in that country and pay less than the $10/day option for my (GSM/CDMA) USA phone to work in these countries.
NOTE: When I travel in my RV, I still like using my usb-Adapter, when I'm on my notebook, to pickup internet hot spots from blocks away... for free! (This is a must if you ask me because then you can dedicated it to your computer and it picks up the internet hotspot just like you would connect to your router at home.
These computer Adapters create a new internet connection option (you just select by clicking on your internet button in the lower right corner of your screen) and because these things have better antenna gain your data rates will be higher and you can connect to hotspots where you park your RV. (Hopefully.) I also use one of these $20 Adapters at home!!!
And if you want a better hotspot than the Verizon Jet-Pack or the T-mobile I travel with this Cell Phone Router for $109 and I use a Ting sim card it designed for GSM phones like T-mobile.
Note: They make more powerful and slightly more expensive WiFi components than is listed above if you want more speed, but these work fine for my needs at the price I was willing to pay.
