      SOSav in the press

      Not registered in the network Samsung Galaxy

      Smartphones from the South Korean manufacturer are popular even despite the occasional very annoying errors, one of which is “Not registered in the network”. Unfortunately, not only the junior budget lines J and A are subject to it, but even the most luxurious, technologically equipped and reliable Galaxy S. Fortunately, like most similar ones, the problem with registering a phone on the network is being solved.

      This alert usually occurs when you try to call someone or send a message. Its reason is quite simple — at the moment when you need to use the network, the telecom operator cannot get the IMEI number of your device (that is, a unique 15-digit number that is «sewn» into every GSM phone by default). On devices of any series, the problem is solved in several ways. nine0003

      Activating and deactivating the Airplane mode

      As you know, when the Airplane mode is activated, the phone stops searching for a network and is temporarily disconnected from the operator. In this case, we need it. Deactivating the mode will force the device to look for an operator again, which will solve the problem.

      1. To get started, go to the «Settings» menu of your phone.

        The standard «Settings» icon for all Samsung devices is made in the form of a gear

      2. Then find the «Other networks» item here and go to it. nine0002 In the settings menu, we need the “Other networks” item — find and click

      3. The first in the list that opens should be the “Offline mode” section. He is what we need.

        Find the «Offline mode» section and activate it

      4. Check the box, confirm the information in the pop-up window.

        A window pops up with information about the mode, confirm it

      5. We wait a couple of minutes and again click on the «Offline mode» item, then uncheck the box and turn it off. After that, the error should disappear. nine0014

      Reinstalling the SIM card

      Another easy way is to reinstall the SIM card. This method is a little more radical than the previous one, however, the probability of its operation is much higher. All you need to do is, depending on the model, either remove the back panel of the phone, or pull out a special nano-sim slot from its side face. Then take out the SIM card, wait a couple of minutes, insert the SIM card back and close the phone with a lid (or put the slot in its place). After that, turn on your smartphone and check if the error appears. It shouldn’t be anymore. nine0003

      Installing the SIM card in another device

      It is likely that the problem lies with the SIM card itself. In order to check its operation, remove the SIM card from the device and insert it into another phone. If the «Not registered on the network» error continues to appear, contact your network operator and ask for a replacement card with the same number.

      Software update

      It happens that the error occurs due to problems in the old software. In this case, you need to update your device software to the latest version. nine0003

      1. First, recharge the battery to 70-80% and connect your smartphone to a Wi-Fi network.
      2. Then go to the «Settings» menu.
      3. Here, find the item «Software Update» and go to it. If this item is not there, find the «About device» section and open it. Here, the “Software Update” section should definitely appear.

        In the settings menu we find the «Software Update» section and click on it

      4. After that, find the line «Update». Depending on the phone model, the line may be called «Download update files manually». We click on it. nine0002 Find the line «Update» and click on it

      5. This starts the process of checking for updates that are currently available to your device. If new software is available, Samsung will offer to install it.

        When downloading new software, it is best to connect to the network via Wi-Fi, not the mobile network

      6. All you have to do is accept the offer and follow the instructions that appear.

        After downloading, the phone itself will give you instructions for actions

      If a software update is not required, the screen will display the phrase “Latest updates installed”.

      If the message «Device changed» appears, contact the service center. This usually indicates that the gadget was rooted or the firmware was changed to a custom one. Unfortunately, it will not be possible to eliminate the emerging problem without the intervention of a specialist.

      Please note that the smartphone must not be turned off during the installation of new software. This action will not only interrupt the process, but may even break your phone. nine0003

      Be careful not to interrupt the process of installing the latest software — this is extremely important for the operation of the system

      If the «Not registered on the network» error appears even after updating the software, contact the service center.

      Installing a SIM card from another operator

      It also happens that in a certain area only one operator and its network is available. In this case, you cannot use the native network of the SIM card installed in the phone. You will have to purchase a SIM card from a new operator. nine0003

      Direct contact with the operator

      If none of the above methods worked, contact the operator by calling the hotline, indicating the problem that occurred and the ways in which you tried to solve it. In this case, the specialist must issue new APN settings (i.e., the settings of the mobile access point through which data is transmitted).

      In general, the “Not registered on the network” error is not that difficult. The main thing is to strictly follow the instructions or turn to specialists in time. nine0003
