iPhone Data Not Working But WiFi Works? 10 Easy Fixes
iPhone Data Not Working But WiFi Works? Here’s How to Fix It
If your iPhone connects to WiFi without problems but mobile data doesn’t work, the issue is usually related to network settings, carrier problems, or software glitches.
You may notice:
- No internet outside WiFi
- Apps not loading on mobile data
- LTE/5G icon showing but no browsing
Let’s fix it step by step.
1. Turn Mobile Data Off and On
Go to:
Settings → Cellular
Turn off Cellular Data, wait 10 seconds, then turn it back on.
This refreshes your mobile connection.
2. Check If You Have Data Coverage
Make sure:
- You have active data plan
- You’re in a strong signal area
- LTE/5G icon is visible
Try moving to a different location to test signal strength.
3. Restart Your iPhone
A simple restart can clear temporary network glitches.
For iPhone 8 and later:
- Press Volume Up
- Press Volume Down
- Hold Side button
- Release when Apple logo appears
This solves many minor connectivity issues.
4. Check APN Settings
Some carriers require correct APN settings.
Go to:
Settings → Cellular → Cellular Data Network
If the fields are empty or incorrect, contact your carrier for the correct settings.
5. Disable WiFi Assist
Go to:
Settings → Cellular
Scroll down and turn off WiFi Assist.
This prevents your phone from switching automatically between WiFi and mobile data.
6. Reset Network Settings
If data still doesn’t work:
Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings
⚠️ This will erase:
- WiFi passwords
- Bluetooth connections
- VPN settings
It will NOT delete photos or apps.
7. Check for Carrier Settings Update
Go to:
Settings → General → About
If a carrier update is available, you’ll see a prompt.
Install it and restart your device.
8. Update iOS
Software bugs sometimes affect mobile data.
Go to:
Settings → General → Software Update
Install the latest stable version if available.
9. Remove and Reinsert SIM Card
Turn off your phone, remove the SIM card, and reinsert it carefully.
This can fix SIM detection issues.
10. Contact Your Carrier
If:
- Data plan expired
- SIM card damaged
- Network outage in your area
Your carrier can confirm and resolve the issue.
