Internet in fobs ? yes no ?

I am about to deploy to Afghanistan. I'm active army. Airborne 11 charlie. My question is do most fobs have internet access ? I'd like to keep in touch with my family when I can. I understand that I won't be able to all the time, but I'd also like to get started on my degree while I'm there. Now Ik that I might go a farely small operating base. Does that matter when it comes to internet access ? Any info would really be appreciated. Thanks
