It is the mundane issues with technology that are most frustrating. For example, your iPhone is on and seems to be connected, but you can’t get data in any app, and you see an error message in Safari that your phone is not connected to the internet. If you’re not connected to a Wi-Fi network, then obviously your cellular data isn’t working – so what should you do? Here are the seven best ways to troubleshoot and solve your problem when cellular data is not working on your iPhone.

Turn off WiFi

Sometimes your iPhone can get stuck between a Wi-Fi network and a cellular connection and stick to Wi-Fi even if it’s the wrong choice. For example, if you’re outside your home, you may be out of practical range for your Wi-Fi network and your iPhone should switch to cellular data. But because the phone can still connect to your Wi-Fi network—barely—it stays connected even if it can’t communicate. Means? Swipe down from the top right corner of the screen to see the Control Center and tap wifi icon disable it temporarily. Your iPhone will now be forced to switch to cellular data and use that instead.

Toggle flight mode

While there are many reasons why your cellular data might not work, one quick and easy way that often gets it working again is to simply turn your wireless connection off and on again. Swipe down from the top right corner of the screen to see Control Center and find Airplane mode icon. If it’s already on, that’s probably your problem – Airplane mode turns off cellular data, so it might have been turned off by accident. But if it’s off, tap the icon and wait a bit, then tap it again to turn wireless back on.

Switch mobile data setting

Similarly, you can manage your iPhone’s mobile data from Control Center, and it’s possible that it’s been accidentally turned off even if Airplane Mode isn’t turned on. Swipe down from the top right corner of the screen to see Control Center and find Mobile data the icon that represents the antenna to the right of the flight mode. If it’s off, tap it to turn it on. Otherwise, tap it to turn it off, wait a moment and tap it again to turn it back on. Now check your internet connection and see if that solved your problem.

Check for carrier settings updates

Although rare, it is sometimes possible that your phone carrier settings may be to blame for the lack of data connectivity. This is especially true if your carrier has recently updated its configuration and for some reason the changes were not automatically updated on your phone. To check for carrier settings updates, run Settings app and then click Generalfollowed by O. If a carrier update is available, you will be prompted to install it now.

Reinstall SIM card

You may need to reinstall your SIM card, especially if it’s a new phone or you’ve changed SIM cards recently. This is easy to do, but you will need to find the SIM eject tool that came with your phone. If it is no longer available, you can also use a thin paper clip. Insert the tool into the hole next to the SIM tray and press gently but firmly until the tray pops out. Make sure the SIM card is properly seated in the tray and then gently push it back in. More detailed instructions can be found here on how to remove a SIM card from an iPhone.

Restart your iPhone

Try restarting your iPhone. This can fix a lot of network and connection related issues and only takes a few minutes to turn it off and then back on.

Reset network settings

If nothing has worked so far, it could be the result of corrupted network settings on your iPhone, which can be fixed by resetting network settings. Save this troubleshooting step for last, because resetting network settings will erase all saved networks, paired Bluetooth devices, and Wi-Fi passwords, so you’ll have to manually reconnect to all your favorite networks.
