- You can also check from the quick settings panel (on Android) or Control Center (on iPhone).
How to Fix:
- If Airplane Mode is on, turn it off and wait a few seconds.
- If it’s already off, try turning it on for 10 seconds, then off again to refresh your connection.
2. Ensure Mobile Data is Enabled
Sometimes, mobile data is accidentally turned off.
How to Check on Android:
- Go to Settings > Network & Internet > Mobile Network.
- Make sure Mobile Data is enabled.
How to Check on iPhone:

3. Check for Network Outages
A network outage from your carrier can disrupt cellular data.
How to Check:
- Call your carrier’s customer service or check their website/social media for outage reports.
- Try using Wi-Fi to visit sites like Downdetector and see if others are reporting issues.
How to Fix:
- If there’s an outage, you’ll have to wait for your carrier to restore service.
- If not, continue troubleshooting.
4. Restart Your Phone
A simple restart can fix minor software glitches affecting cellular data.
How to Restart:
- Android: Press and hold the Power button, then select Restart.
- iPhone: Press and hold the Side button + Volume Down button (iPhone X and newer) or Power button (older iPhones), then slide to power off.
Turn your phone back on and check if mobile data works.
5. Check Your Signal Strength
A weak signal can prevent mobile data from working properly.
How to Check:
- Look at the signal bars on your phone.
- If you have one or no bars, your connection is weak.
How to Fix:
- Move to an open area with better signal coverage.
- If you’re indoors, try going near a window or stepping outside.
- If you have persistent poor signal issues, consider using a signal booster.
6. Check Data Limit and Carrier Restrictions
If you exceed your data limit or have an unpaid bill, your carrier may suspend your data services.
How to Check:
- Log into your carrier’s app or website and check your data usage.
- Look for messages about data limits or unpaid bills.
How to Fix:
- If you’ve run out of data, upgrade to a larger data plan.
- If your bill is unpaid, make a payment and restart your phone.
7. Reinsert Your SIM Card
A loose or damaged SIM card can cause cellular data problems.
How to Check:
- Turn off your phone.
- Remove the SIM card using a SIM ejector tool.
- Inspect for scratches or damage.
How to Fix:
- If dirty, clean the SIM gently with a microfiber cloth.
- Reinsert the SIM securely and restart your phone.
- If the SIM is damaged, contact your carrier for a replacement.

Incorrect network settings can block mobile data access.
How to Reset Network Settings:
On Android:

An outdated software version can cause cellular data issues.
How to Check for Updates:
- Android: Go to Settings > System > Software update.
- iPhone: Open Settings > General > Software Update.
How to Fix:
