I just checked my phone and that prompt - Mobile Hot Spot is not listed, how do I get that prompt on my phone?
BB model 9330 is a Curve model and is not mobile hotspot capable.
If you actually have a 9930 then your handset has both a keyboard and a touchscreen display. If this is true, what OS version are you running? You may need to update the OS (operating system) to utilize the mobile hotspot function.
