Mobile data downloading problems

You may try some of these steps, please check after each step...

1. Check your signal strength. Make sure that you are in an area with good cellular reception. You can check your signal strength by looking at the signal bars in the status bar at the top of your screen.
2. If you are using a cellular data plan with limited data, you may be experiencing slow speeds or dropped connections because you have reached your data limit.
3. If you are using a VPN, this could be interfering with your cellular data connection. Try disabling your VPN and see if that fixes the problem.
4. Update your carrier settings. Your carrier may have released new carrier settings that can fix cellular data issues. To update your carrier settings, go to Settings > General > About. If there is an update available, it will be listed under "Carrier settings." Manually update your carrier settings on your iPhone or iPad
5. Turning on Airplane Mode for a few seconds and then turning it off can refresh your cellular connection. You can enable Airplane Mode by swiping down from the top right corner of the screen to access the Control Center or by going to Settings > Airplane Mode.
6. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
7. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
8. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

The Parts and Service History section of your iPhone's settings will show you if any parts of your iPhone have been replaced or repaired. If it says "Cellular Issue Detected", this means that iPhone has identified a problem with the cellular antenna in your iPhone.

If the Parts and Service History section says "Cellular Issue Detected", and you have already tried the troubleshooting steps above, then you will need to take your iPhone to an Apple Store or authorized repair center for further diagnosis and repair.

If your iPhone has a history of Camera/Display/Anetana replacement / Repair / Service from an un-authorised service provider then it is possible that Apple may refuse to service your iPhone if it has been previously serviced by an unauthorized service center.
