Finding it is not at all simple and that we could even perform the check tests that include some smartphones without really finding it out.That is why we must assess all kinds of causes and depending on each one to act accordingly to make the coverage and the network work on the mobile as if nothing had happened.
The first question we must ask ourselves is whether it is a problem of the phone, the SIM or our company.The most recommended option in each case to find out are the following:
But before moving to more complex solutions, we must ensure that the SIM card is well connected, as a bad placement is one of the most repeated causes that derive in failures.We must ensure placement and also clean it, in case dust particles are causing this.
Solutions
To ensure that the smartphone ends up solving these situations provided that it is in our hand is done with the following processes.We begin with the most basic and repeated causes, but ending as more complex process that would end up avoiding any error linked to the network.
Restart
The easiest and most effective thing to solve a problem lack of signal on the smartphone is to restart the device.It is as simple as holding the off button and selecting the corresponding option when doing this, the device will erase the cache memory and restore any processes that may be interfering with the optimal performance of the device and of course, in access to the network ofdata.
Airplane mode
The logical thing is to think that before getting here you have verified that the airplane mode, which prevents calling and receiving calls and connecting to the network, is deactivated.But airplane mode can also help manually connect to the service provider.All you need to do is activate the airplane mode and then turn it off so that the device tries to connect to the supplier.

Without signal
When we continue without being able to connect to the network, we must check in the following interactive map if the area in which we find has 4G or 5G connection, since if not we could be far from an antenna that allows us the ability to receive a signal.In that case, all we can do is move personally to a higher point or where the coverage is not affected.
Correct APN
APN configuration can also be affecting the good device performance.This is something that several Xiaomi users have discovered that, after updating their smartphone saw how their phones stopped being able to connect to the network.
To configure it correctly we will have to repeat the following process:
- Primero deberás ir al menú de Ajustes.
- Ahora seleccionamos Tarjetas SIM y redes móviles
- Escogeremos la tarjeta SIM en la que tienes el problema.
- Y tocamos sobre Nombres de Puntos de Acceso.
- Para finalmente darle a crear APN nuevo.
- Dónde debemos añadir los datos que nuestra operadora nos ha facilitado.
After completing all the data, we will choose this configuration as the default.Then, we restart the mobile and when the signal should work.
Network operator
It is possible that your smartphone has trouble finding your binding link automatically and, therefore, you should select them yourself to help you find the key. Esto es algo que puedes hacerlo navegando en Ajustes > Redes móviles > Network operator.Here a list of suppliers should appear allowing you to select the correct one and see if this solves the problem.
Ping test
One of the reasons why a certain telephone can show the "not available network" or "non -service message is because it is connected to a signal with problems, but it is not able to identify it, something that we will avoid with this test.
All you have to do is mark the following code on the phone app score:*#*#4636#*#*
In doing so you will enter the service mode of your device, where a different options will appear.You must select information about the phone and then choose ‘Execute ping test’, for which we will have disconnected the Wi-Fi.Once you finish the test, go down to the bottom of the menu and verify the data sent and received.Once this is done, restart the phone and check if the problem is solved.
Restore network
If your device continues to have problems connecting and others affect Wi-Fi or Bluetooth, there may be a generalized problem with the configuration.These adjustments can sometimes be corrupted, which will leave your device unable to connect to nothing around and end up showing the dreaded message.
Fortunately, you can restore the specific configuration at any time.This will not delete any of your applications, photos or other data as if you would make a hard reset.All you will delete are your stored wi-fi passwords and other connection information.With this, again connect to the Internet.Do it following these steps.
- Abre la aplicación Configuración en el móvil.
- Desplázate hasta abajo y pulsa Sistema o Ajustes adicionales, dependiendo del dispositivo que tengas.
- Elige Restablecer o Restablecer opciones y dentro pulsa sobre Restablecer la configuración de red.
- Confirma que deseas dar este paso y acepta el mensaje en pantalla.
- Tu dispositivo se reiniciará y la configuración se habrá borrado y restablecido.
Restore mobile
Some problems are more difficult to solve than others and sometimes, how with the lack of signal implies trying a more aggressive solution.Returning the phone to your factory status, as just out of the box, is one of the most effective ways to eliminate errors inherited on the phone.
As we have said countless times, this step implies restoring the factory configuration of your phone, a process that deletes all phone data, except software.So you must make a backup and move all the photos and value files to another place to not lose them.Then we will follow these steps:
- Entramos en los Ajustes del smartphone.
- Escogemos Copia de seguridad y restablecimiento.
- Escogemos Borrar todos los datos.
- Para finalmente restablecer todo el teléfono.
