Using the cellular network to download or upload content requires more power than doing the same transfer over Wi-Fi. When the users reach the data limit, they may incur overage charges or the connection may shut down.ĭata transfers also consume power. Some plans have limits on the amount of data that can be transferred per month, or in some cases, over a three month period. The Kindle Fire HD 8.9" 4G (2nd Generation) tablet includes a bundled mobile network plan. For Fire phone and Fire tablets (3rd and 4th Generation), the user must purchase a plan from a carrier. However, if a Wi-Fi connection is not available and the user has a mobile network plan, the devices connect to the mobile network.


By default, these devices connect to Wi-Fi. In addition to Wi-Fi connectivity, the Fire phone, Fire HDX 8.9 (4th Generation), Kindle Fire HDX 8.9" (3rd Generation), Kindle Fire HDX 7" (3rd Generation), and the Kindle Fire HD 8.9" 4G (2nd Generation) tablet can connect to mobile networks if the user has a mobile network plan.
