Hey folks -- this isn't SPAM.... I have no affiliation with this company. I think so far 5 of us here at Texas Airstream Harbor have signed up for this company. They provide UNLIMITED internet over the AT&T network (Cricket) for $60/mo. If you keep up with internet pricing, you know that is an amazing deal! Before I stumbled on this company I was trying to BUY an unlimited Verizon account for $500 to $700 bucks.
Anyway, the company is here https://www.4ghs.com
I would recommend that you get this AT&T hotspot to use with it. Tell the 4GHS people you have your own device and ONLY NEED THE SIM card.
The 781S hotspot linked above is the latest model for AT&T network and is compatible with the most frequencies.... so you will get the best coverage that AT&T has to offer. But if you already have an AT&T hotspot you can use the sim card in that too.
With a deal this great, I am just hoping it lasts awhile. Sometimes these companies who resell internet on the major networks come and go. But get it while you can and cross your fingers that it stays around. There isn't much risk in signing up because it is month to month, no deposit, and you own your own device.
