We live rural and a electrician was here with his mobile hotspot device and laptop. He has success with a connection and I know you can hook up 5 computers to it. I also would like to find out if it is better than an aircard?
Since the aircard is our only source for the internet, I would love to hear from some of you techy smart people on the mhd. Any help appreciated!

My epic phone works as a mobile hotspot. But, I would have to pay 39.99 a month service fee for it. Since we have cable, we don't use it.

For people who have to use their laptops on the go a lot it is useful because you are not constrained by local wi-fi networks which are generally unsecured and often have use fees attached. A mobile hotspot allows you to run your computer off a mobile hotspot device that ties in with the wireless cell-phone networks. The new smartphones generally have the ability to act as mobile hotspots, but it does have another charge per month. I know I can get it for my Droid through Verizon for another $30/mo.
