I know the iPad does not, a lot of these tablet companies don't have that slot trying to keep it compact in size and with that that's how the whole Internet provided with the tablet came about. I have not seen any tablets that have an Internet card slot if you have a phone you could tether to avoid the monthly cost
I have an iPad. I use my iPhone, which is jailbroken, and have it set as on demand wifi so the iPad will connect to it when needed on it's own.
Most of the new smart phones are hotspot capable, but you have to pay for the service. If you have a iPhone, jailbreak it and download the app. If you have a droid, open source the software and your good to go. Problem solved.
I'm an iPhone guy, but I work with android stuff, too. In all honesty, if you aren't paying a monthly fee, you aren't going to get any sort of free wireless Internet, outside of wifi. If you already pay for data, on your phone, then wifi hotspot off of that is your best bet.

I know I had like an 8 month hiatus at one point but damn who is left on here from the old regulars? I know 2 or 3 of us off the top of my head but damn... Soccer I haven't seen post in forever, Rap is gone although he probably got banned a few times by other mods... lots of other regulars are...
Figured I'd throw this out there for the DIY'rs. Harbor Freight has recalled their 3 ton jack stands. Be careful if you are still using them.
