Galaxy S20 No 4G LTE signal [Easy Fixes]

In addition to 4G LTE, Samsung’s latest Galaxy flagship devices are already 5G capable. In fact, these are the first major family of smartphones to incorporate 5G signal depending on the service provider or region. The fact that 5G isn’t yet available in all countries, many would opt (or will have no choice but) to use 4G LTE networks. If ever you encounter an issue with your galaxy s20‘s 4G LTE signal, I’ve mapped out a few solutions for you to try. Here’s a quick guide on how to deal with signal issues, particularly no 4G LTE signal on your galaxy s20.

Before you proceed, verify and ensure that your account standing is good and your services status are active. Note that no cellular signal issues can also be attributed to some problem with your account, including unsettled balances. If everything is good with your account and you are certain that the place you’re in has 4G LTE signal available but still couldn’t get a 4g LTE signal to work on your galaxy s20, then you can go ahead and eliminate software-related triggers with these subsequent methods.

Elaborated below are basic yet effective solutions to network connectivity issues, particularly no signal on the Galaxy S20 and other Android devices. These are recommended workarounds you should try before opting for service.

  1. Restart the phone (soft reset).

    If 4G LTE signal was available and your device has already used it and then it stopped working, then it’s probably just a random glitch affecting the phone’s cellular system. The simplest way of dealing random system flaws like this is by carrying out a soft reset or restarting the phone. Aside from being a system breather, a restart also eliminates minor glitches that are inflicting random errors to your phone’s cellular network functions. The standard way to restart/soft reset a Galaxy S20 is by pressing and holding on the Bixby/Power button then tap on Restart. Alternatively, you can press and hold the Bixby/Power button and the Volume Down key simultaneously for about 45 seconds and then release both keys when the phone restarts.Either way prompts your device to end all running services and reboot the system. A soft reset or standard restart procedure does not affect any saved information on the internal memory and therefore does not result in permanent data loss. That being said, you don’t need to back up files beforehand. how to fix galaxy s20 no 4G LTE signal - soft reset reboot galaxy s20

  2. Toggle Airplane Mode on and off.

    Another effective solution that has been proven by many to work wonders when it comes to resolving wireless connectivity issues including no signal is the so-called Airplane Mode trick. It basically works by turning Airplane Mode on for a few seconds and then back on again. Performing the Airplane Mode trick gives a simultaneous restart to all wireless features of your phone and thereby eliminates any existing flaws. To carry out the Airplane Mode trick, simply access your phone’s Settings-> Connections-> Airplane Mode menu and then toggle the Airplane Mode switch to turn the feature on for a few seconds and then back on again.All wireless services and relevant features are disabled when Airplane mode is turned on so make sure you turn it off again. Restarting the phone while Airplane Mode is turned on is highly recommended for better results. how to fix galaxy s20 no 4G LTE signal - toggle airplane mode on and off

  3. Reset network settings.

    A network settings reset is often used among other advanced solutions to complex network problems including signal errors. As the name implies, it will erase all current network settings on the phone including saved Wi-Fi network, Bluetooth connections, APNs and more. As a result, the original network options and values are restored. Any erroneous network configuration will therefore be removed and corrected. To reset network settings on the Galaxy S20, open the Apps tray then go to Settings-> General management-> Reset menu and then tap the option to Reset network settings. If prompted, tap Reset settings, enter your PIN or password then tap Reset settings again to confirm.After the reset, your device restarts and then loads up the default network values. To get back online and use internet services, you will need to re-enable Wi-Fi and reconnect to your Wi-Fi network.See if that restores your phone’s 4G LTE signal too. how to fix galaxy s20 no 4G LTE signal - reset network settings

  4. Reinstall the SIM card.

    The problem could also be with the SIM card in use. No signal issues can also be due to the SIM card being dislodged from the tray or it could be because the SIM card system on your phone has been corrupted. To rule out such possibilities, reinstalling the SIM card can help.To do this, turn off your phone then remove the SIM card from the tray. You will need to use a SIM ejector to pop the tray out from the phone. Using the one that comes with the phone is recommended but if you don’t have one, you can use a small paper clip as an alternative.If you have some spare functional LTE-ready SIM card that’s compatible with the Galaxy S20, try to replace your SIM card and see if that would yield a positive outcome. If your phone manages to obtain a 4G LTE signal using a different SIM, then the problem is apparently with the first SIM card you’ve got. how to fix galaxy s20 no 4G LTE signal - remove reinsert SIM card

Still got no 4G LTE signal on your Galaxy S20?

Contact your network service provider to escalate the problem if none of the above solutions is able to fix it. There might be some ongoing technical issues in your area that are affecting network services, particularly 4g LTE signals.

If tech support isn’t available, then you may opt to troubleshoot further and try carrying out more advanced solutions including a factory reset or master reset. This should help fix the problem if complex system errors are the underlying cause. Just don’t forget to back up all critical information beforehand because failure to do so would result in permanent data loss.
