How can I make my iPhone into a personal hotspot without get charged?

He Hotspot takes directly from your megas because it uses your plan as the source for the internet and then emits Wi-Fi signals for other devices to connect to the internet through your phone! So to connect to the internet without using your megas You can:
1. Use your neighbor's Wi-Fi but ask them before you do so (until you fix your home internet)
2. Ask someone that has extra megas with you at home to provide you with hotspot until your home internet is back.
