- To fix your iOS 17 cellular data issues, try toggling both Airplane mode and Mobile Data in the Control Center and reseating your SIM card.
- Here are 11 of the top ways to fix your iPhone when your cellular data isn’t working after iOS 17 update.
Some iOS 17 users seem to experience an issue where cellular data is not working even when in an area with good cellular reception. With this particular problem, the cellular data connection keeps getting lost even though the cellular status icons (like 3G, 4G,5G or LTE) and the signal strength bars show it is connected to a cellular network.
If you do not have a cellular data connection, you won’t be able to connect to the Internet unless there is Wi-Fi. If you are having this issue, you may see an error message in Safari that your phone isn’t connected to the internet. If you’re not connected to a Wi-Fi network, then clearly, your cellular data isn’t working — so what do you do? Here are the top 11 ways to troubleshoot and solve your problem when cellular data isn’t working on iPhone running iOS 17.
Fixing the iOS 17 cellular data issues
Try these troubleshooting steps until your issue is resolved:
1. Make sure that Cellular Data is enabled
First, make sure you’re not in Airplane Mode, which cuts off all your phone’s external connections. To check this, swipe down from the top right of the screen to reveal the control center. Here, make sure that the icon that looks like an airplane isn’t enabled. If it is, tap it to turn Airplane Mode off.
You should also check that Cellular Data is turned on. Start the Settings app on your iPhone and tap ”Cellular” to make sure Cellular Data is toggled on. If it isn’t, tap the Cellular Data toggle to turn it on.
2. Turn off your Wi-Fi
Sometimes your iPhone can get caught between a Wi-Fi network and cellular, and stick with Wi-Fi even when that’s the wrong choice. If you are outside your home, for example, you might be just outside the practical range of your Wi-Fi network, and your iPhone should switch over to cellular data. But because the phone can still connect to your Wi-Fi network — barely — it stays connected, even though it can’t exchange any data. The remedy? Swipe down from the top of the screen to reveal the Control Center and tap the Wi-Fiicon to disable it. Then check if you can connect to the Internet over cellular data.
3. Toggle Airplane mode
While there are a lot of reasons your cellular data may not be working, one quick and easy trick that often gets it working again is to simply toggle your wireless connection off and back on again. Swipe down from the top right of the screen to reveal the Control Center. Tap Airplane mode to turn it on, wait a few seconds, and then tap it again to turn it off. Now check if cellular data starts working again.
4. Turn Cellular Data off and on
If cellular data is still not working on your iPhone, try switching it off and back on again and see if that fixes the issue. Swipe down from the top right of the screen to reveal the Control Center and look for the Cellular Data icon, which is an antenna to the right of Airplane mode. Tap it to disable, wait a moment, and tap it again to turn it back on. Now test your internet connection and see if that solved your problem.
5. Update iOS
If your iPhone’s cellular data is not working because of an iOS bug, an update could fix it. Check if there is an iOS update and if there is, update your iPhone. Start the Settings app on your iPhone and then tap General, followed by Software Update. If there’s an iOS update available, tap Update Now and follow the onscreen instructions.
6. Check for a carrier setting update
This update usually occurs automatically. But you can do it manually, too. Carrier settings updates are how your carrier brings their cellular-related software updates to your phone. Your cellular data issues might be fixed by a carrier settings update. Start the Settings app on your iPhone and then tap General, followed by About. If there’s a carrier update available, you’ll be prompted to install it now.
7. Are you using VPN?
VPN is known to cause connection problems. Are you using a VPN service? If you are not using a VPN service, do you have any VPN profiles installed? Let’s see if this is the problem:
- If you are using VPN, turn it off. And test your issue. If the issue continues, see the next step.
- Start the Settings app on your iPhone and then tap General, followed by VPN & Device Management then VPN. Tap the (i) button next to the VPN profiles you have and tap Delete VPN. Now test your problem again.
8. Reseat your SIM card
If cellular data is still not working, you might need to reseat your SIM card. To do that, find the SIM card removal tool that came with your iPhone — you can also use a pin or very thin paperclip and insert into the hole near the SIM card try until the tray pops out. Make sure the SIM card is seated properly in its tray and then reinsert it carefully.
9. Restart your iPhone
If simply reseating the SIM card didn’t do the trick, restarting your iPhone may solve the problem. Here’s how to restart your iPhone, regardless of which model you own.
10. Reset your network settings
If cellular data is still not working, try to reset your iPhone’s network settings. Treat this as a last resort, because it will also reset your Bluetooth paired devices and Wi-Fi network passwords. But if cellular data is still not working on your iPhone, it might be worth the inconvenience.
Start the Settings app on your iPhone and then tap General, followed by Transfer or Reset iPhone. At the bottom of the screen, tap Reset, then Reset Network Settings.
11. Contact your cellular service provider
