My iphone is not connecting to internet

The most common reasons why your iPad or iPhone won't connect to Wi-Fi include a poor connection signal, an incorrect Wi-Fi password, your Wi-Fi or mobile data settings, restricted network settings, or even a bulky phone case. A weak Wi-Fi connection can also mean you need to increase your internet speed.

Restart your device. If restarting doesn't work, switch between Wi-Fi and mobile data: Open your Settings app and tap Network & internet or Connections. Depending on your device, these options may be different. Turn Wi-Fi off and mobile data on, and check if there's a difference.
