Each phone model has its specific features. Apparently, the Wi-Fi Hotspot feature was not included in the 9220. You'll find that even if a feature is available on a certain model, the carriers are free to support it or not so your Model A phone might not have the exact same features as your friend's Model A phone if he/she uses another carrier.

In this case, the 7.1 operating system allows Mobile Hotspot, but that feature is still controlled by your mobile provider and must be enabled by them.
