For those with Droid smart phones there is an APP that is a hot spot for WIFI. It is free and uses the data of your smart phone that you already pay for. It is secure just like your modem wifi at home. It is called FOXFI. It also works on more than one computer at a time. It works everywhere the 3d or 4g or 1g works.
