Systems and methods for selectively switching between primary data connection modes of a mobile device

A mobile device, comprising:

• a housing;
• a WLAN communication device retained by the housing, wherein the WLAN communication device is configured to allow the mobile device to communicate with one or more Wi-Fi networks;
• a WWAN communication device retained by the housing, wherein the WWAN communication device is configured to allow the mobile device to communication with one or more cellular networks;
• a motion detector retained by the housing, wherein the motion detector is configured to detect motion of the mobile device;
• a timing device retained by the housing, wherein the timing device is configured to detect a time period of the motion of the mobile device;
• and
• a switching control unit retained by the housing, wherein the switching control unit is in communication with the WLAN communication device, the WWAN communication device, the motion detector, and the timing device, and
• wherein the switching control unit is configured to selectively and automatically switch the mobile device between the WLAN primary data connection mode and the WWAN primary data connection mode based on the motion of the mobile device and the time period of the motion of the mobile device.
