If a user reports a malfunction with the phone's network, it should be approached with high seriousness. The network section of the phone is the most important and complicated electronic circuit. Without a functioning network, the basic function of the device is unusable. While it would require much space to explain the detailed workings of the network, we offer basic guidance for understanding and solving these problems.
Designing and developing a mobile phone involves multiple engineers and experts from different fields. Understanding the detailed work of the mobile device's network can be complicated for the average technician. Therefore, we advise dealing with network problems with professional literature to understand the basic principles of network operation and successfully resolve failures.
Network malfunctions may be caused by hardware or software errors. Following the official procedures of most manufacturers, testing must be carried out before any service interventions to determine the difference in the device's correctness before and after service. However, the equipment used for this purpose can be expensive and is typically seen in larger service centers. If you cannot afford such equipment, consider renting a service center for testing.
If the network test shows an error, try repairing the device's software through RF calibration. However, some electronic elements may be defective and need to be replaced, or there may be issues with the coaxial cable or poor connections. After hardware repair, the software should be reinstalled, followed by another test to ensure the servicing was successful.
Successfully addressing these types of faults will earn the trust of your clients, improve your rating, and position you higher than the competition in the market of servicing mobile devices.
