I nee dto usemy ipad mini - wifi version sometime sin area where there is no wifi. So the solution to getting connection is I can get my Ip5 to act as a hotspot so that my ipad mini connects. Now i have a 2gb plan and as I understand I need to bump upto 5gb for me to be able to get the hotspot feature. Is the connection relaible and fast? Do I have to connect through bluetooth or wifi. Also how much more willI be paying to get this hotspot service?
