Bugs on the iOS build especially on the beta builds, can be very detrimental to the usual fluid user experience on the iOS.

So, just to be on the safer side, you can update the iOS on your iPhone.

  1. Launch the Settings app.
  2. Then tap on General.
    navigate to General
  3. Next, tap on Software Update.

Update the App Which is Not able to run on Cellular Internet

The app on your iPhone that cannot connect to the cellular internet may be running an old build with bugs. So, try updating it first.

  1. Open the App Store application.
  2. Tap on your Profile Picture at the top-right corner.
  3. Check in the list of apps waiting to install a new update.
  4. If the concerned app is listed there, tap on the button Update present beside the app.

After updating the app, check if it can connect to cellular data and run smoothly or not.

Turn off VPN

When you enable VPN, the device is routed to a server placed in some region other than the actual region where the iPhone is located. It may happen that the VPN server your iPhone is connected to maybe too busy with lots of service requests, and hence you end up facing slower cellular internet.

Unless you require VPN, I suggest disabling it and then trying to use the cellular internet.

  1. Open the Settings app
  2. Scroll to the option VPN.
  3. Tap on the switch beside VPN to disable it.

Disable Flight Mode

Often flight mode may have been enabled, and users forget to disable it. With the flight mode enabled, you cannot use the cellular internet on the iPhone.

  1. Open the Control center on your iPhone.
  2. Tap on the Flight Mode icon to disable it.

  3. Even if flight mode is not activated, you can activate it for a few seconds and disable it. This trick often works in fixing minor network problems.

Contact your ISP

Your internet service provider may have undertaken some maintenance work for which the entire coverage area may have been affected. So, you can use customer care contact for your ISP or reach out to them via social media and confirm regarding the maintenance work.

If they affirm about the repair job causing the cellular internet to not work on the iPhone, then you must wait until they finish the maintenance.

Remove and Re-insert the SIM card in your iPhone.

Another effective fix is to remove the SIM card from your iPhone. Then make sure to re-insert the SIM card back into the iPhone. If not correctly fixed in the SIM tray, the SIM card may not work, causing the cellular network not to work as intended.

When the SIM card is not properly put in the SIM tray, then you won’t see the network signal on the home screen.

Disable Wi-Fi Calling on the iPhone

Often users have reported that disabling the WiFi calling feature helps them restore cellular network connectivity on their iPhones. So, you should try it as well.

  1. Go to the Settings app.
  2. Then tap on Mobile Data.
    open mobile data
  3. Scroll down to Wi-Fi calling and tap on it.
