This is a stand-alone internet router and device. (I bought this while traveling thru the Midwest with little to no TMobile reception, and bought an unlimited prepaid plan from from Verizon - gives your fast speeds and unlimited data!) - Made by Inseego (Novatel), the MIFI 8800L is an oval plastic box that measures 4.45 by 2.80 by 0.75 inches.
