2. Toggle cellular data off and on again.

On old iPhones with Home button: Swipe up from the bottom to access Control Center. On iPhone X or later, swipe down from the top right corner to access Control Center. Now, turn off the toggle next to the Cellular data. Wait for some time, and then turn it on.

3. If you’re traveling internationally, make sure that your device is set up for data roaming. Go to Settings > Cellular > Cellular Data Options > Data Roaming.

Maybe you did not insert the SIM card correctly. Therefore, remove the SIM and then reinsert it again. First, turn off your iPhone, then use the SIM-eject tool to remove the SIM card. Then, reinsert it. After that, turn on the device.

You might need to contact your carrier:

  • If the SIM card is damaged or doesn’t fit in the SIM tray, ask your carrier for a new SIM card.
  • If you transferred your SIM card from another device, ask your carrier if your SIM card works with your iPhone.

5. Reset your Network Settings

Resetting network to factory default has often helped me in fixing network related issues. So, there is a high possibility that it can troubleshoot the problem. Note that it will reset Wi-Fi networks and passwords, cellular settings, VPN as well as APN settings that you’ve used before.

Go to Settings > General > Reset > Reset Network Settings. Enter your device passcode and confirm.

  1. Make sure that your device is connected to a Wi-Fi or cellular network.
  2. Tap Settings > General > About. If an update is available, you’ll see an option to update your carrier settings.
