iPhone cellular data is working only when you are inside of the cellular coverage area. So if you are outside of it, the data is surely not working on iPhone. To check your iPhone's cellular coverage area, locate the status bar at the top of your phone's screen to observe the signal.

3Re-Insert SIM Card

SIM cards being damaged or in bad contact can be the reason why your iPhone is not connecting to the internet cellular data. It's simple to fix it, just take out the SIM card and confirm that it is intact. Consider inserting the same SIM card into another device and checking if it works. Reinsert it back to your iPhone if it works, or replace the SIM card if it fails to work on another device.

4Disable WiFi Calling

While WiFi calling is a great feature that allows your phone to automatically switch from regular phone calls to a WiFi network in case it offers a better signal, it may sometimes interfere with cellar connection. If you're already on a cellular connection, switching off WiFi calling can be a quick fix. There are two ways of doing this:

Click on Settings > Cellular > WiFi Calling and tap on the toggle to switch it off.

Click on Setings > Phone > WiFi Calling and then tap the Wi-Fi calling slider to make it grey.

To disable the VPN, just go to the VPN settings, switch it off and do a restart to ensure that you are completely disconnected.

6Check Date and Time Settings

If the iPhone cellular data not working problem occurrs when you are using a certain app, then chances are that incorrect iPhone date and time settings are related to the network malfunction.
