Once you own a smartphone, mobile data or the internet becomes a necessity. Having no access to Google Maps, Flipboard, or any other way to stay in touch with friends and family until you lose your internet connection is a terrifying realization.

In other words, it is catastrophic when your Android cellular data service comes down. Problems with your ISP (Internet Service Provider) service from AT&T, an expired AT&T Data plan, incorrectly adjusted network settings on your phone, or an issue with the iPhone itself may be to blame for the problem.


Switch The Airplane Function On & Off

Here is how you can turn on and off airplane mode on android and iPhone devices:

On Android

Turn On Airplane Mode on Android Via Settings

  • On/Off the Airplane Mode by going to Settings > Network & internet > Airplane Mode.
  • Swipe down from your home screen and tap Airplane Mode to enable or disable it.


  • On Android, go to Quick Settings and enable Airplane Mode.
  • Swipe down from your home screen’s top.
  • Turn on Airplane Mode by tapping it.
  • Your phone has entered Airplane Mode.

On Iphone

  • By swiping down from the top-right corner of your iPhone, you may access ‘Control Center.’
  • Find the ‘Airplane’ icon and switch it on. Wait for a few seconds and turn OFF the Airplane Mode. Now, check if you can retrieve or use AT&T Data without any issues.

Manually Put in Settings Of Your APN

After the update of your system, it could be possible that the settings of your APN become corrupted. If a basic reset does not fix this problem, you would have to enter the APN details manually. Again, not all gadgets come equipped with this feature to choose from.

On Android

  • Go to Settings, followed by Network & Internet. After that, go to Mobile network and finally to Access Point Names. To acquire Names of Access Point on models Android 11 and earlier, tap Mobile Networks and then Advanced.
  • In the top-right corner, tap the “+” icon.
  • Fill in all your APN network details, which you must be able to access on the official website of the carrier.
  • Save your new settings and later select them from your APN list on the device.

On iPhone

  • On iPhone, go to the Settings App and look for Mobile Data under Mobile Data Options which is below Mobile Data Network.
  • For both categories of APN, enter ‘Internet’ (Cellular Data & Personal Hotspot)
  • You can try on the Mobile Network resetting the APN data by going for the Reset Settings choice. Examine again to see whether the issue has been resolved.


Take Out and Insert Again Your SIM Card

People usually roll their eyes when the idea of “rebooting their phone” or “removing and reinserting their SIM card,” comes up, but these must be the first choice when trying to fix the issues with the cellular data. If the problem persists, you can also try to use another SIM card to figure out the root of all your issues.

Moreover, there is some extra tip that can help you in restarting your phone.

  • Switch on airplane mode prior to restarting your device.
  •  After thirty seconds pass, airplane mode needs to switch off.
  • If you are still having issues with data, turn on airplane mode and switch off your smartphone. Wait for a minute before turning on your phone and switching off airplane mode. Now, wait another few seconds and turn on the cellular data. If you still do not get data, continue the above process.


Enable the Right Network Mode

Let’s start with the simplest solution. It is highly likely that your phone’s network mode is set to something that does not provide strong coverage either after updates or plainly in the device’s default settings. It is the most common situation.

If you own a 4G phone, make sure that you constantly turn on 4G through your network settings. Or, if your smartphone is not 4G but it is using a system that reinforces it as a network mode, there are chances your phone is trying to connect with these signals even if it is failing.

To change the preferred network of your phone, go to Settings and then Network & Internet. Tap on the Mobile network option and then finally on Preferred network type to make your choice. If you have a 4G phone, set Auto for 4G/5G/3G so that it can easily and always connect to the strongest network.

Some devices support only 4G or 5G and do not permit people to change between networks.


Check for Carrier Updates

In the event that the problem continues to exist, you can attempt to resolve it by updating the iPhone’s carrier software.

  • Launch the ‘Settings’ app, navigate to ‘General > About’, then scroll down until you reach the ‘General’ menu and tap it.
  • Tap the “About” menu option, and then wait to see whether a pop-up that says “Carrier Settings Update” appears on the screen. If this is the case, select “Update” from the menu, and then wait for the update to be applied.


Check for Software Updates

Here is how you can check software updates:

On Android

  • Tap Settings from the Home Screen of your Android phone or tablet.
  • Scroll all the way down the settings screen until you see About Phone or About Device and touch on it.
  • On the following screen, select System updates or Software updates.
  • Tap the Update Now button on the next screen.
  • After that, you’ll get a pop-up asking you to confirm that you want your device to look for and install updates if any are available.
  • Your device will immediately begin searching for updates.
  • Following that, you will receive a pop-up stating that “Your System is Up to Date” or telling you that updates are available.
  • If an update is available, you will get a screen advising you of its availability. To begin the process of updating your handset to the most recent version of Android available for your device, click on Download & Install.

On iPhone

  • Open the ‘Settings’ app on your iPhone and navigate to ‘General > Software Updates.’
  • Once updated, restart your phone to see if the problem has been repaired.


Check To Enquire About Your Mobile Data Limit

Every Android feature has the capability to customize the limit of mobile data and provide notifications if, by chance, you exceed that limit. In most situations, these can’t be activated automatically. But it is something that you can do. There are also chances that your data usage has increased and you’ve forgotten to update your new limit.

Another option for those working with limited data is to set up a metered Wi-Fi network. Follow the steps listed below to do so:

On Android

  • Open Settings and then Network & Internet followed by Data Usage.
  • Scroll to the  “Limit mobile data usage” choice. Switch it on and off.
  •  After tapping on the prevalent default limit, enter the new one.

For Android 11 model and earlier ones:

  • Go to Settings —> Network & Internet —> Mobile network.
  • Ensure Cellular data is enabled and choose Data limit & Warning.
  • Make certain that you have switched off the Set data limit or that it’s not less than the limit of your network.

On iPhone

  • On the iPhone, go to Settings > Cellular.
  •  Scroll down to see your overall data consumption for the billing period, as well as how much data your apps have consumed, in descending order.

It’s perfectly acceptable to check the data on your phone, but doing so will simply provide you with an understanding of what aspects of your phone are consuming data. If you have a family plan or a plan with multiple lines, you will need to go into the details a little bit further to determine who is using how much.


Reset Network settings

Sometimes the only solution to your problem is to switch back to the original factory settings. A variety of factors give rise to problems with mobile data functioning, such as apps, bugs, and system updates. To reset the network settings, take the following steps:

On Android

  • Move to Settings follow it by Network & Internet and then Reset Network Settings.
  • Choose Reset Settings and tap on it again to confirm.
  • Restart your smartphone.
  •  Once it is done, you will be asked to re-enter the details of Wi-Fi and Bluetooth devices.

If the problem persists, you may wish to try a factory reset, although this should be your final resort if nothing else has worked.

On iPhone

The problem could be caused by incorrectly configured network settings on the iPhone. You can resolve the issue by performing a network reset.

  • In iPhone, open the ‘Settings’ App and navigate to ‘General > Reset > Reset Network Settings.’
  • Wait for the procedure to finish, then switch off your device and stand by for another 10 seconds. Now restart your phone and check if the issue is solved.


Factory Reset Your Device

Here is the way to ensure the device’s factory reset on iPhone and Android:

On Android

  • Make sure the device is plugged in or has adequate battery power to go through the reset process.
  • If that doesn’t work, tap on the Settings app.
  • Choose System.
  • Navigate to the Reset menu.
  • Select and remove all data from the factory reset.
  • Select Erase all data.
  • If asked, enter your PIN.
  • Choose Erase all data and wait for the phone to do its thing.

On Iphone

  • Open Settings and then select General. There you’ll see the Transfer or Reset iPhone option.

You can make use of iCloud’s extra storage to send your app and data to a new device if you are planning to change from one iPhone to other. Just follow the method mentioned above.

  • Tap to Erase All Data and Settings.

After deleting all the data and settings, restart your iPhone. Then go to your phone’s backup in order to restore files. If you don’t want to do that, you simply set up a new device.


Contact AT&T Support

In the event that you are still unable to resolve the problem, you can get in touch with AT&T Official Support or go to the official site for AT&T Support, report the issue to them, and ask for the answer. You can reach their support line by dialing 611 on an AT&T phone or by calling their toll-free number, which is 800-331-0500.
