The Novatel GSM MiFi lets you turn your SIM card from AT&T into a MiFi personal hotspot. In this review we do a range of speed tests both through an iPad and a laptop. We also go over how you can use the MiFi to share files with multiple people if you have files on a microSD card. Overall, if you're looking for a more economical way to get WiFi anywhere, the Novatel GSM MiFi is a fantastic choice for those of you that already have an unlimited AT&T data plan. You can grab one over at Negri Electronics for about $260.
