Tethering and Mobile Hotspots

Tethering is a process where you share the internet connection of your mobile device to allow another handset to access the internet. The most common way of doing this is using your device as a Mobile Hotspot. This allows your device to create a secure Wi-Fi network for other nearby Wi-Fi enabled devices to connect to. 
 
How much does it cost to set up a mobile hotspot? 
If you have an applicable data bundle, data used by tethered handsets will come out of your bundle allowance. If you do not have an applicable bundle, data charges will apply for any data used by any connected handset, if your mobile handset is connected to the internet using the mobile network.  
 
Where is tethering available? 
Tethering is available in most countries, although there are still some operators and devices that do not support this feature.  

Some networks do not allow tethering on BlackBerry OS (BBOS), which includes the Blackberry 9720.
