We have an "unlimited" plan with AT&T, but that's unlimited talk, text and cellular data. The mobile hotspot data (ie, internet) is limited to 15GB per month per phone on the plan. So I get 15GB / month and my wife gets 15GB / month. If we're not streaming video, that's more than enough. My experience has been that streaming video (Netflix, YouTube, DirecTV NOW, etc) sucks up about 1/2 GB per hour. So between us, we can get about 60 hours of video per month. As soon as we a) bring the grandkids on board; or b) start tailgating during football season and want to watch games we very quickly hit our limits.
I did find this vendor:
Skyroam Hotspot | WiFi Wherever You Travel. You buy their Solis X wifi hotspot (connect 10 devices) for about $180 list price OR their standard Solis (connect up to 5 devices) for about $150 list price. You can also rent the device for $8.99 per day, which would work for a short trip. Then you can either buy unlimited wifi data for a 24 hour period for $9 (which would be perfect for us on game day); OR 1GB of data per month for $9 per month & buy as many 1GB as you need; OR unlimited data for $130 per month (special offer currently for $100 per month). No contracts, cancel any time. NO CLUE how good the service actually is and whether the company is long term viable. But definitely something I plan to check out as tailgating season draws closer.
Would love to hear if anyone has any experience with SkyRoam?
