Enables WiFi or Bluetooth Hotspot on your Android phone without a Hotspot plan from your carrier. No rooting required! Just install and turn it on. Bluetooth mode works for all phones. WiFi mode currently works on most Samsung phones and Motorola phones, LG Optimus/Vortex/Ally, ZTE N762, HuaWei Comet. WiFi mode does NOT work on any HTC phones or the first Motorola Droid/Triumph, use Bluetooth mode instead.
You can connect from any tablets or computers. Access Point is infrastructure mode with WPA2 security. FoxFi usage is covered under the same phone data plan you have.
Here are some tips to help your usage:
1. On some models if you run into WiFi problem after using the Hotspot, simply reboot your phone to clear the issue.
2. For some Samsung phones if your computer is not able to get an IP address, try to turn on WiFi on the phone first and make sure it does not connect to any WiFi network, then turn on FoxFi.
3. FoxFi is tested on non-rooted phones. If your phone has a rooted ROM it may or may not work.
4. When WiFi hotspot is activated you may also see a hotspot notification of the built-in WiFi hotspot feature. Please ignore it. As long as you do not sign up for a tether plan you won't be charged.
