Software-related factors that can adversely affect your phone’s cellular signal reception include faulty settings, firmware update bugs, and corrupted SIM card data among others.

Signal issues that are attributed to the hardware are often due to a damaged SIM card, defective network-related components like a dysfunctional built-in antenna or worse, a broken phone itself.

Ruling out software-related culprits from the software layer is highly recommended before rushing to a service center.

Troubleshooting Galaxy A53 5g No service error

Performing the following procedures will help address cellular network problems on your Samsung phones, particularly those that are inflicted for firmware glitches.

Before you begin, make sure that your phone’s software is up-to-date. This is highly recommended to ensure optimum performance among system apps and services including network-related features.

To manually check for new updates on your Samsung Galaxy phone, go to Settings-> Software Update menu. If a new firmware version is available, follow the onscreen instructions to download and install the new update.

Go ahead and try each of the following methods to rule out software-related factors that might have triggered the No service error to occur on your device.

Solution #1: Restart the phone (soft reset).

If everything was working perfectly fine and then suddenly the No service error shows, it could be just a minor glitch that was triggered by some random network flaw. This is usually the case if the network reception suddenly becomes intermittent. 

To clear our minor software glitches that might have inflicted no service, restart or soft reset your Samsung Galaxy A53. Doing so will not just fix minor network errors but likewise any other errant apps and system services that are acting up.

  • To restart/soft reset the Galaxy A53 5g, press and hold the Power and Volume Down keys and then release both when the Power off prompt appears. Tap the Restart icon and then tap Restart again to confirm.

Wait for your phone to finish restarting. It should be back up and running after about 30 seconds.

You can also perform a force restart by pressing and holding on the Power button for at least 10 seconds and then release when the Samsung logo appears.

Restarting the phone using any of the above methods does not affect any user information so you won’t lose any important apps and saved files on your device.

Solution #2: Enable/disable Airplane mode.

Another simple tweak that has been proven to work wonders when dealing with various network connectivity issues in mobile devices is the so-called Airplane mode trick.

  • To access and manage the Airplane mode settings on the Galaxy A53 5g device, just navigate to Settings-> Connections menu then tap the Airplane mode switch to turn the feature On. All wireless features of the phone including Wi-Fi, Bluetooth, and Cellular networks are then disabled. After a few seconds, toggle the switch to turn Airplane mode off again. Doing so re-enables the phone’s wireless features.

Give your phone a few moments to re-establish network signals and see if the No service error is gone. Be sure to stay in an open area where there are no possible signal barriers or interference.

Performing this trick simultaneously restarts all the wireless features and services on the phone. It also turned out to effectively clear out minor flaws from the network system that’s causing relevant issues.

Solution #3: Enable manual network search.

Enabling manual network selection on the phone can also be considered among other potential solutions. Performing this workaround is recommended when dealing with network signal issues while roaming.

  • To access and manage this setting, go to the Home /Apps screen and then tap Settings-> Connections menu and then select Mobile networks. On the succeeding window, tap Network operators then turn off Select automatically. If prompted, read the message and then tap OK to confirm. That will disable automatic network mode on your device.
At this point, just wait for your phone to manually search for available networks.

You can always put the network selection mode of your Samsung Galaxy A53 5g phone to automatic mode when you’re no longer roaming.

Solution #4: Remove then reinstall the SIM card.

As earlier mentioned, a corrupted SIM card data can also be the main reason as to why your phone isn’t getting cellular signal and instead prompts a No service error. To clear this out, removing and reinstalling the SIM card on your phone is recommended. 

Before you remove the SIM card, turn off your device completely to avoid damaging the SIM card or the device itself.

While the phone is completely powered off, use the SIM ejector to eject the SIM tray from the side of the phone. When the tray is ejected, gently pull it out and then remove the SIM card. Care to check the SIM card for any visible signs of liquid or physical damage. If it looks good, place it back into the tray in the same orientation and placement before you remove it. When the SIM card is secured, push to lock the SIM tray back into your phone.

Turn on your phone and then wait and see if the No service error is gone already.

Solution #5: Reset network settings.

Performing resets can be considered among the last options if none of the basic solutions worked. There are different types of resets that you can choose from. But the most relevant is the option to reset network settings.

As the name implies, this reset will delete all currently added network settings including automatic network changes or overrides from recent software updates that might have caused unexpected network conflicts.

A network reset is different from a factory reset as it does not affect any user data from the phone’s internal storage. That said, you won’t lose any downloaded apps and saved information from your device.

To reset network settings on the Galaxy a53 5g, just head over to the built-in Reset menu under General management. 

You can view and access a step-by-step walkthrough on how to reset network settings through this page.

After resetting network settings, you will need to reconfigure Wi-Fi, Bluetooth, Cellular/mobile data settings and other relevant features individually, according to your preferences.

Is your Samsung phone still showing No service?

The above solutions are usually good enough when resolving minor network flaws on the phone unless other more complex causes exist. Should you wish to troubleshoot further, you can try the following tweaks.

Try another SIM card.

To determine whether or not the problem is due to a damaged SIM card, try to use another SIM card that’s active and compatible with your Samsung phone. If your phone manages to establish a cellular signal and the No service error doesn’t show while using a different SIM card, then that clearly denotes that the problem is with your SIM card.

Should this be the case, getting a new SIM card replacement from your network service provider is the key to fixing the problem. Just let them know exactly what happened and ask them to get a new SIM card with the same phone number.

Factory reset (Master reset).

Performing a factory reset is usually deemed as a drastic solution to complex system issues that cause recurring errors on the phone. This is usually carried out if all else fails to fix the problem. 

If you suspect that a critical system error is the underlying cause of the problem, then you may consider resorting to a factory data reset.

But before you do, be sure to back up all your important files to a secure location so that you’d still be able to retrieve and use them afterwards. Note that a factory reset will erase everything from the system including your downloaded apps and saved files, custom settings and other system preferences.

After the reset, the phone resets to its factory default state so everything in the system goes back to their original configuration. The latest software version will likewise be installed on the phone.

Don’t forget to consider checking for any ongoing outages that may affect cellular reception in your area. Contact your network service provider for more information regarding network outages.

Repair options.

If your phone lost signal after dropping or getting it wet, then that could be a direct indication of hardware damage. Some critical network components on the device have likely obtained some sort of physical or liquid damage from the previous incident and the No service error emerges as the primary indicator.

Should you wish to seek hardware assistance, take your device to the nearest authorized Samsung service center and have it diagnosed thoroughly by a technician. Don’t forget to avail warranty if your device is still covered.

Seek more help

Contact your network service provider to escalate the problem for further assistance if none of the given solutions is able to fix the No service error on your Samsung phone.

The error could be due to some technical issues from your service provider’s end (network base) rather than on the phone’s operating system.
