wifi phone

A Wi-Fi phone is a device that makes calls over Wi-Fi instead of cellular networks. Some are Wi-Fi-only, while others also have cellular capabilities. They're common from China, where many phones don't support GSM or any major carrier, making them more suited for home use or gaming.

After realizing my Chinese OP phone with 12GB of RAM wasn't compatible with my cellular carrier, I decided to use it as a wifi phone for gaming.
