OP here... thanks again everyone for all the advice and suggestions!
I ended up noticing a hotspot device on sale at
Walmart, but since I was definitely not knowledgable about these, I wanted to talk to someone local about all the options out there.
So I went and talked to one of the guys at
Best Buy to see what they offered, and if dh was going to be using the internet a ton while away from wi-fi, most of the plans they have would've worked out really well.
But the problem is, the only times he really would like a hotspot is a few times/month for a few minutes, and bit more frequently in the summer while we go camping for him to check e-mail, etc. Most of the time we're around wifi. All of their plans have you buying $25-$30 top-up cards, which expire in 30 days (which I think is kind of ridiculous, but just my opinion).
I kept asking him about a no-contract option that the time would not expire in the 30 days, and he said there was no option like that.
So I hopped over to Walmart just to look at the device I had seen in the paper, and it was exactly what I was looking for. So I ended up buying that, getting a $10 top-up card (which never expires), and will be giving that to dh for Christmas.
be used with an itouch or just or a phone?
These are meant to be used with something besides a phone that has its own access.. such as an itouch, ipad, kindle, etc.,

In our case, it can have 5 devices accessing it.. so thinking if we go on vacation, etc, then dd's will be able to use the wifi on both their Touches in the car, and dh and I will be using it with his iPad and my Touch.
