    There is nothing worse than one smartphone does not takeespecially when using a high spec smartphone such as a Samsung Galaxy S10 or Apple iPhone XR and not having a single signal line on the device. It can be really frustrating and annoying since without network services, you won't be able to make calls, receive or send text messages, and you won't even be able to connect to the internet. (one brick) This could get even more annoying if you need to make an urgent phone call or are about to receive an important message.




    How to improve your phone's network signal

    Why does my smartphone not take

    This problem could even make matters worse if this happens regularly. So, to put an end to this problem forever, we have come up with some solutions that will help you solve this problem for life. In this guide, we will demonstrate some tricks that could easily fix this problem. Try every method shared in this tutorial and rest assured that something is sure to work with your phone.

    The general rule of the smartphone has no signal

    Try your prepaid SIM in another smartphone to see if it works. This is the starting point for figuring out if the problem is your SIM card or your phone. In most cases, if the SIM inserted in another phone still doesn't work, she is the culprit. You just have to go to an authorized center of your network operator. If it works… you just have to keep reading.


    The smartphone does not pick up because the SIM card is dirty

    It is likely that the SIM has dust particles and does not allow proper contact with the slot, so you need to wipe it with a clean cloth.



    Why is my 3G or 4G network not working?

    Check the SIM slot on the phone if the phone says "No SIM card"

    In many cases, if the smartphone does not detect the SIM card, it is very likely that the SIM card has been inserted incorrectly, which is why the phone cannot recognize the SIM. On the other hand, the SIM card may have been inserted in the wrong direction and this may cause the smartphone not to read correctly. Here's what to do if this is your case:

    1 pass. Turn off your device and remove the back cover from your smartphone.


    2 pass. Take out the battery and remove the SIM card from the SIM card slot.

    3 pass. Clean the SIM card with a clean piece of cloth or tissue paper to remove any dirt or dust.

    4 pass. Reinsert the SIM card and restart the phone.


    Wait for the restart and let it sit for a few minutes. The network and cellular service should be up again, but if the problem persists, move on to the next method.

    The smartphone does not take? So let's clean up the Android cache and data

    Wiping the cache and data from your Android phone helps to solve many system related problems such as not detecting the SIM card. But we will not perform a simple cache cleanup and data wipe, but we will try to wipe the cache partition from the recovery menu. Follow these steps to wipe the cache partition from the recovery menu:


    1 pass. Turn off your smartphone and let it sit for a few minutes.


    2 pass. Now, turn on the phone by holding the Power and Volume Down buttons at the same time to enable the Quick Start Menu options.

    3 pass. Use the volume up and down buttons to navigate through the options and launch the recovery menu.

    4 pass. Choose the “Wipe cache partition” option and tap the Home button to select it.

    Give your phone a few minutes to clear the cache and data from your phone and then restart it. Your phone should now show the network signal perfectly, if not, continue with the next method.

    Change network settings

    The smartphone may not show the network signal if the network settings are not configured correctly. In many cases, the settings can be changed due to the installation of incompatible apps or during a software update. If this is the scenario, follow these steps to change the network settings:

    1 pass. Tap Menu and open Settings.

    2 pass. Scroll down and tap "SIM Cards & Mobile Networks". (This option name may vary from phone to phone but will look more or less similar to what we said.)


    3 pass. In the Network Mode section, you should see an option that says “Preferred Network Type”.

    Step 4. You will see various options like LTE, CDMA, GSM, etc. Choose the supported option on your smartphone and save your changes. Wait a few moments and the phone should now show the network signal.

    Perform a factory reset

    You can try doing a factory reset, which essentially consists of formatting the phone and having it revert to the way it was when you bought it. Formatting your phone is very simple, but remember that you will lose all data and photos stored in the device.


    Try turning off the mobile signal

    This alternative can solve the problem of yours smartphone does not take due to a network problem. To do this you need to access one of the secret menus by entering the following code * # * # * # * # 4636. Then go to the About Phone tab. Here, you will find several options. Click the one that says Turn off mobile signal. After a couple of minutes, turn it back on. Then you need to restart your phone and check if it works.

     

    If you've tried all the methods shared in this guide, your problem should be solved. But, if the problem persists, the problem is no longer in the internal settings and perhaps requires special attention. In that case, you can take your smartphone to the nearest technical service.
