What to do when your iPhone cellular data isn’t working

Have you ever found yourself frustrated with your iPhone’s cellular data not working properly? It can be a real hassle, especially when you’re relying on it for important tasks. But don’t worry, we’ve got you covered with some simple fixes that you can try right now.

Check Your Cellular Network and Data

Before diving into troubleshooting, it’s essential to ensure that you’re within your carrier’s coverage area. Sometimes, a weak signal or network outage can be the culprit behind your iPhone’s data issues. Check your carrier’s coverage map or contact them to verify if there are any ongoing network problems.

Restart Your iPhone

A quick and easy fix for many iPhone-related issues is to restart your device. This simple action can help clear out any software glitches that might be causing your cellular data woes. Press and hold the Power button until the “slide to power off” slider appears, then slide it to turn off your iPhone. After a few seconds, turn it back on by pressing the Power button again.

Check Airplane Mode

Sometimes, Airplane Mode might accidentally be turned on, which disables all wireless connections, including cellular data. Check your iPhone’s settings to ensure that Airplane Mode is turned off. You can find this option in the Settings app under “Airplane Mode.” If it’s enabled, tap the switch to turn it off.

Turn Off Wi-Fi

Your iPhone may prioritize Wi-Fi connections over cellular data, even when you’re out of Wi-Fi range. To force your device to use cellular data, turn off Wi-Fi temporarily. Swipe up or down from the Lock screen to access the Control Center, then tap the Wi-Fi icon to disable it.

Turn On Cellular Data

Make sure that your Cellular Data option is enabled in your iPhone’s settings. Go to Settings > Cellular, and ensure that the switch next to “Cellular Data” is turned on (green). If it’s off, toggle it on and off a few times to refresh the connection.

Check for Carrier Settings Update

Occasionally, issues with cellular data can be resolved by updating your iPhone’s carrier settings. Check for any available updates by going to Settings > General > About. If a carrier update is available, you’ll receive a prompt to install it.

Reinsert Your SIM Card

If your iPhone uses a physical SIM card, it’s worth checking to see if it’s properly inserted and undamaged. A dirty, damaged, or loose SIM card can cause connectivity issues. Follow the appropriate steps to safely remove and reinsert your SIM card, or consider contacting your carrier for a replacement.

Check for a Software Update

Keeping your iPhone’s operating system up-to-date is crucial for maintaining optimal performance. Check for any available software updates by going to Settings > General > Software Update. If an update is available, follow the on-screen instructions to install it.

Reset Your Network Settings

As a last resort, you can try resetting your iPhone’s network settings. This will erase all saved Wi-Fi networks, Bluetooth devices, and VPN settings, so proceed with caution. Go to Settings > General > Reset > Reset Network Settings, and enter your passcode if prompted. Your iPhone will restart after the reset is complete.


Dealing with iPhone cellular data issues can be frustrating, but with these simple troubleshooting steps, you can often resolve the problem quickly. Whether it’s a simple restart or a more involved network settings reset, these tips can help you get your iPhone back online and connected.


1: Why is my iPhone not connecting to cellular data?

Your iPhone may not be connecting to cellular data due to various reasons, such as network coverage issues, software glitches, or incorrect settings. Try troubleshooting steps like restarting your device, checking Airplane Mode, and ensuring that Cellular Data is enabled.

You can check for network outages in your area by contacting your carrier or visiting their website. Many carriers provide outage maps or status updates on their websites or through their customer service channels.
