Meizu M5 No Network

One of the most common problems faced by owners of Chinese devices based on the Android OS is the unstable operation of 3G and 4G coatings. Network outages on the Meizu M5, M2 Mini and other mobile devices can be caused by a number of reasons, both external and internal. Some malfunctions can be dealt with at home, while with others, the phone will have to be taken to a service center. Let’s see why the Meizu smartphone does not catch the 3G (4G) network and what to do in a particular case.

Causes of Bad Signal Mobile Networks

All modern phones support at least two types of networks:

  1. GSM It is the global standard for digital cellular communications. It is through it that the subscribers are connected and the conversation is conducted.
  2. 3G (4G) network. Mobile connection responsible for Internet access.

The faulty operation of these networks on the Meizu M3S or other device in most cases is to blame for the same malfunctions. Therefore, for simplicity, we will consider both types of communication as a whole.

If your phone constantly loses its network and cannot provide stable 3G (4G) Internet, this may indicate such problems:

  • unstable coverage of a cellular operator;
  • mechanical damage to the mobile device;
  • software malfunction.

Each case needs a specific approach and requires individual consideration.

Problems with a mobile operator

Every year, mobile operators providing their services in the domestic market try to improve the quality of coverage and open high-speed 3G and 4G Internet even in the most remote corners of the country. However, today there are still a lot of areas with unstable signal reception. Therefore, if the Meizu M3 Note does not catch the mobile network well, the problem is most likely due to the coverage.

To confirm or refute the guilt of the operator, you can do the following:

  1. Through the settings of Meizu enter the section “About the phone”.
  2. Select the “General Information” tab.
  3. Click on the line “SIM card status” (in some firmware it is called differently).
  4. View signal strength on the gadget.

Stable is considered a level of.75 dBm. At a lower value, try inserting your SIM card into another phone and do the same operations on it. If even there this indicator does not reach the norm, it can be stated with full confidence that the problem really lies in the quality of coverage and nothing can be done about it.

If on another mobile phone the signal is normal, perhaps your Meizu M3 Nout has lost the network due to the fact that the manufacturer equipped it with a weak amplifier. In this case, through the device’s menu, you can disable 3G (4G) communication and work only on 2G, thereby improving the quality of reception. However, the Internet will not work with the smartphone with such settings, which is unacceptable for most users.

Mechanical and hardware malfunctions Meizu

If the phone says “No network” when trying to connect to a mobile operator, it is possible that the problem is mechanical or hardware in nature. Try the following:

  1. Reboot your smartphone. If a minor hardware failure occurs on it, it should be fixed after a restart.
  2. Take out the SIM card and clean the contacts of the card holder with a soft rag. If they are oxidized or contaminated, the connection and the Internet on the gadget may disappear.
  3. Enter the Meise engineering menu and in the Telephony. BandMode tab see if the frequencies your operator is operating on are turned on. If they are turned off, activate them by checking the boxes and pressing SET.

Also try to remember if the phone was hit hard or if water got on it. So, if Meizu used to work stably, and after falling there is no network signal, it is quite possible that one of the modules responsible for communication failed. It can be:

  • amplifier;
  • antenna;
  • connector;
  • microcontroller, etc.

To accurately determine a non-working element and repair a smartphone, it is better to seek help from a specialist.

Software crashes

Often, problems with cellular communication occur after flashing a mobile device using third-party software. To eliminate such a malfunction, you must:

  1. Copy all important information from a smartphone to an external drive or PC.
  2. Download firmware suitable for your phone from and save it to the root of the internal memory.
  3. Enter the engineering menu of Meizu. To do this, on the turned off device, you need to simultaneously hold down the Power and Volume Up keys.
  4. Mark the items shown in the figure and click Start.
