These two iPhone settings could be incorrect depending on your carrier 🤔 . Open settings tap cellular. Then select cellular data options. And finally voice and data. 🗣️ . If you don't have a good 5G signal everywhere you go, select LTE. It might be actually faster and I guarantee you'll get better battery life. 🎊 . For the next setting, go back to the previous page and select Data mode. Unless if your Wi-Fi is completely horrible, there's no reason why we should enable allow more data on 5G.
