Does the damage of Radion affect the SMS function? Detailed explanation of fault master

Radio is mainly used to control the communication signals of mobile phones, including telephone and internet access functions. In fact, when the mobile phone leaves the factory, the radio hardware module has been built in, and what we brush in is only the software application level. Because the software level determines the frequency band allocation of the radio hardware module to receive and transmit signals, the title of hardware radio is weakened, so we call this kind of radio software-level east-west radio.

The radio is broken, and the short message function doesn't work.

If it is software-level damage, it can also be repaired by brushing; If it is a hardware level, only the corresponding components can be repaired and replaced.
