How to Automatically Join a Wi-Fi Network on an iPhone

To automatically join a Wi-Fi network on an iPhone, you can follow these steps:

1. Open the Settings app on your iPhone. 2. Tap on Wi-Fi. 3. Make sure that Wi-Fi is turned on. 4. Find the Wi-Fi network you want to automatically join from the list of available networks and tap on it. 5. Enter the password for the Wi-Fi network if prompted. 6. Once you have successfully connected to the Wi-Fi network, tap on the "i" icon next to the network name. 7. Turn on the "Auto-Join" toggle switch. 8. Your iPhone will now automatically connect to this Wi-Fi network whenever it is available and in range.

Note: If you're unable to join a Wi-Fi network automatically, it could be because the network is not configured to allow automatic connections, or there could be a problem with your iPhone's Wi-Fi settings. In such cases, you may need to contact your network administrator or Apple support for assistance.
