Tether It implements all possible tethering options without requiring a tethering plan from your carrier, or rooting your phone. You use this app to share your smart-phone's Internet connection with your computer, tablet or other devices. Only one click is required to turn WiFi, Bluetooth or USB tethering on or off. The WiFi access point created by Tether It supports WPA2 security. The tethering usage is covered by the general data plan you have from your carrier; no separate tethering plan is required. This can save you significant amount of money per month. The WiFi mode is the fastest and easiest way to tether, however, it may not work on all phones due to blocking implemented by some carriers. Bluetooth and USB tethering modes work for all phones and carriers. You can try WiFi mode first. If it prompts you to call your carrier, that means Tether It has failed to activate the WiFi access point, and you should use Bluetooth or USB mode instead. PLEASE READ THE FOLLOWING BEFORE PURCHASING: We recommend that you try the trial version of Tether It first before buying the premium version. WiFi tethering mode may not work on all smart-phones and/or every carrier. Some phone updates may also break WiFi mode. Please install the trial version first and make sure it works to your satisfaction. We do not provide any warranty due to many things we cannot control. Carriers have been finding ways to interfere with unpaid tether usage (such as through system updates).
