    While Samsung has made users satisfied by the unique features of their Galaxy S4, it is important to mention that this handset is not flawless and users have already encountered several issues with it. No signal is one of the most common ones.

    Problems such as not registered on the network, no network coverage on the Samsung galaxy S4 AT&T, Version, Sprint, T-Mobile US are also very common. The signal error is not a carrier-related problem. So, if you try a SIM card from a different provider, you will still face this problem. Here, we are going to share a few solutions that will help you get rid of the issue.



    Potential fixes for Samsung Galaxy S4 no signal issue


    Method 1:
    To fix No signal issue on Samsung Galaxy S4, navigate to

    • Settings
    • Connections
    • More networks
    • Mobile networks—Network mode
    • Network operators
    • and then select automatically preferred network.

    Alternatively, click on each of them until it works. If GSM network (2G) is not working, toggling to (3G) can solve the issue.



    Method 2
    • Open dialer in your handset and enter *#*#4636#*#*
    • Run Ping Test
    • Tap on GSM Auto (PRL) in the drop down list
    • Click on “Turn Off Radio” and restart the device to check if the problem is solved

    In most cases, the SIM card may be the problem. Ensure that the SIM card is placed correctly.



    Method 3
    If you have tried all the above steps and the issue is still there, the next step is to check for the software update. To do so, head towards Settings> About device> Software update> Check for update.



    Method 4
    • Navigate to Settings> Mobile network settings
    • Now hold the power button and the home button altogether when you are in the mobile network settings to power off the device.
    • Next, remove the battery.
    • Press the Power button and home button together around 10 times.
    • Now press and hold the power and home button for 2 minutes which will drain out all static charges.
    • Re-insert the battery and boot up the device with the SIM Card. But do not attach the back cover.
    • The SIM card is to be removed and re-inserted around 3 times while the phone is on.

    • You will be then prompted to restart your Samsung Galaxy.
    • Restart the device and the problem will be fixed


    Method 5
    The final step is factory reset, but make sure to backup all your data. Here is how to perform factory data reset:

    • Turn off your device first.
    • Next, hold down the Home, Power, and Volume Up button altogether for few seconds till Android logo appears.
    • Release the buttons then. Use Volume down button for highlighting the options and Power key to confirm it. Highlight the factory reset option and confirm it using the power button.
    • Next, select 'delete all user data' and confirm it.
    • Wait for few seconds to see the 'reboot system now' option and select it. The phone will be restarted then and you need to set it up from scratch again.
