A service called FreedomPop offers a Connected Car package which includes a Photon mobile hotspot device, micro USB travel charger and power bank. The kit includes 500MB of monthly data usage free at 4G speeds. The Photon device is capable of producing a Wi-Fi hotspot for up to eight devices.
Other mobile data and phone providers such as AT&T, Sprint and Verizon Wireless offer similar mobile hotspot devices with varying functionality. Mobile hotspot devices compatible with one wireless provider may not work with another, so it is important to check before making a purchase. AT&T offers the MiFi Liberate and Unite 4G, Sprint offers the Overdrive Pro, Tri-Fi 4G LTE and Zing 4G LTE, and Verizon Wireless offers the Jetpack line of MiFi devices to name a few.
Many modern smartphones have the functionality to be used as a mobile hotspot, but bandwidth is limited to the wireless provider's terms. Additional fees may also apply when using a mobile device as a hotspot. The practice of using a mobile phone as a hotspot is called tethering. Advanced users may wish to download an app that provides tethering functionality, although these apps may not function as well as those pre-loaded by mobile service providers due to network and device restrictions.
