Resolve Mobile Data Issues on Samsung S23 Ultra, S23, S23 Plus

Unquestionably, we cannot survive without Wi-Fi because of two reasons; it is pocket friendly, and secondly, for faster internet speed. However, at the same time, when you’re away from Wi-Fi, access to Mobile Data is as important as Wi-Fi. For no reason, some users’ mobile data is not working on Samsung S23 Ultra, S23, and S23 Plus. To troubleshoot that, we’ve enlisted detailed solutions to get rid of it.

One of the most common reasons why is mobile data not working on Samsung is weak signal strength; if you’re facing issues while calling or messaging, then move yourself to another location. Let’s fix Samsung S23 internet connection issues.

Fix Cellular Data Not Working on Samsung S23 Ultra, S23, and S23 Plus

Check Data Plan and Availability

All carrier plans have restrictions; the more you pay, the more they give, and it works this way. First and foremost, when you encounter mobile data not working on Samsung, ensure you have an active internet plan, and mobile data is not exhausted for the day. This information is easily available in the dedicated carrier’s app, or you can connect with the support team via call or chat.

Sometimes background app updates consume mobile data way faster than anything, and it is unfeasible to track such activities. No worries, you can renew the data plan, take a booster plan for a day, or wait for the next day for the plan to renew.

Check Mobile Data Limit

Another setting that could prevent mobile data is Data Limit. If the set Mobile data limit for a day or month is already exhausted, Samsung S23, S23 Plus, or S23 Ultra won’t let you use mobile data unless the limit is increased or the setting is disabled. Here’s how to disable the Mobile data limit on Samsung S23, S23 Plus, and Samsung S23 Ultra.

1. Go to the Settings app.
2. Tap Connections > Data usage.
3. Tap on the Settings cog next to the date range.
4. Make sure the Set data limit is disabled or increase the Data limit.

Update Software

Samsung pushes software updates periodically to deal with minor glitches, and mobile data not working on Samsung is no different. And it’s the same with carriers; they also release updates to make network connectivity stronger and better than earlier. Connect the device to Wi-Fi and follow the steps to update the phone.

1. Go to the Settings app.
2. Scroll down to the Software update.

1. Tap Check for updates.
2. Download and Install the software update if available.

Toggle Airplane Mode

Airplane mode can disconnect your phone from all the wireless connections in one tap. Since the Samsung S23 is not connecting to mobile data, and we’re still figuring out the reason behind that, give it a try by enabling the Airplane mode. Once the phone disconnects from wireless connections, you can disable the Airplane mode. This trick has worked earlier, and hopefully, it will work for you too.

1. Pull down the notification bar and tap on Airplane mode to enable and disable.

Ensure your Samsung S23 has cellular coverage

Check the signal strength and verify how many bars your mobile network has. If it’s one or zero, the Samsung phone will go offline. In this situation, move away from metal stored; best to go in the open surrounding where are there are lesser buildings. 

Enable Data Roaming

If you are on an International tour, make sure to turn on data roaming on the Samsung phone. For this, go to Settings App > Connections. Now, select Mobile Networks. And at last, toggle to enable data roaming. 

Set Date and Time Automatic 

Cellular data may not work on the Samsung S23 series if the time and date aren’t configured correctly. Thus, we suggest turning ON Time and Date Automatic by following the steps below.

1. Navigate to the Settings App.
2. Choose General Management.
3. Tap on Date And Time.

1. Now, enable the toggle next to the Automatic Date And Time. 

That’s It!

Turn off VPN

VPN is good for accessing the data of other geographical regions. But if it’s a free VPN, it can hinder the feature of the Samsung S23 series, including Mobile Data. Therefore, try turning it off, and check for the problem. 

Disable Wi-Fi Calling

Often, when the Wi-Fi calling feature is turned ON, and Samsung S23 series receives appropriate Wi-Fi network. Then the normal calling immediately gets tweaked to the Wi-Fi calling. And which eventually affects standard calls and mobile data. To turn it off, swipe down the Notification Panel and tap on the Wi-Fi Calling Icon to disable it. 

Force Reboot Device

Restarting the device once a week is recommended to rule out minor glitches and restart the system. Here’s how to force restart Samsung S23 Ultra, S23, and S23 Plus.

1. Press and hold the Volume Up and Power button until the Samsung logo appears on the screen.

If a simple restart doesn’t work for you, jump on to the next solution.

Reset Network Settings

Since it’s a network-related issue, resetting network settings will help you clear up the wrongly configured settings you are unaware of. There is a good chance that the problem will be fixed, but it will erase all the saved Wi-Fi passwords, Mobile data, and Bluetooth configuration from the system.

1. Navigate to the Settings app.
2. Go to General management > Reset.

3. Select Reset network settings.

4. Tap Reset Settings to confirm.

Reset All Settings

Reset All Settings is more advanced than resetting network settings. Doing this will reset everything except Security settings, Language Settings, Accounts, Personal data, and Settings for downloaded apps.

1. Go to the Settings app.
2. Tap General management. Select Reset.

4. Choose Reset All Settings.

4. Confirm, Reset Settings.

Remove and Reinsert SIM Card

Is your SIM too old? Are you sure that the SIM is inserted correctly? Power Off the phone and remove the SIM Card using the ejector tool. Clean the SIM Card and insert it again correctly.

Alternatively, if the problem persists, you can insert a different SIM Card to verify that the problem is with the SIM or the phone itself.

Factory Data Reset

Lastly, a factory data reset is the only solution to bring back the device from all sorts of inconsistencies. The only downside of Factory Data Reset is it will wipe out the whole device, including your personal photos, videos, contacts, apps, etc., and restore it to default settings, just like a new phone.

Therefore, you must back up the phone before resetting it.

Here’s how to factory data reset.

1. Go to the Settings app.
2. Tap General management > Reset.
3. Tap Factory data reset.

1. Read the warning and lastly, confirm, Reset.

Contact Carrier

If all of the tricks mentioned above don’t work for you, it’s time to contact Samsung Support and raise your concern, as they are a group of trained technicians that can firmly diagnose the problem and fix it accordingly.
