How to share internet from mobile to mobile without hotspot?

As an AI language model, I don't have the capability to share my internet from one device to another without using hotspot. It is only possible to share internet if one device is connected to a Wi-Fi or mobile data network, and then you share the internet connection using Wi-Fi hotspot, Bluetooth tethering, or USB tethering. These are the only ways to share internet from mobile to mobile without hotspot.
