On February 11th we finally found an ISP we can afford that supplies the gigs we need. They don't have an affiliate program and we are still trying them out so don't want to mention who it is, just yet. However, we're very happy with the performance, so far.
One downside of it is that there's no "unlimited" plans available. It's just past the middle of the month and we have used nearly 1/2 of our allotment. By the end of the month, it's going to be close. It runs on the same Solaris Hotspot that Skyroam uses except the plans available from the company we are using are cheaper and give you a lot more gigs than Skyroam does.
Another downside is that it uses the strongest signal. The strongest signal doesn't always mean the fastest signal. That's what we loved about using the Netgear Nighthawk with an external antenna; with a little software to modify the device, we could tweak it to use the band coming from the fastest signal and point the antenna at it.
So far, with an average ping of 25, average downloads of 15 mbps and average uploads of 10 mbps, we're not going to complain. I was hesitant to get it, at first, because I noticed on their Facebook page that they are deleting negative comments. A lot of people were complaining about being double billed, not getting refunds, and being billed even after returning the hotspot to close their account. The only way to contact them is through an online form, email or online chat. There is no phone number to talk to an actual person.
We're keeping fingers crossed that we don't have issues if it ever comes down to having to stop service.
