Network problem

[Mcsam]

my redmi 7 developed a network problem. the network reception is not stable. is this a factory fault? because so many people using redmi products are complaining bitterly

Is there any solution to Redmi 7 network problem?.?

Maybe the fréquencies supported by your device don't match with your carrier....

Here is the redmi note 7 section , maybe you could try in the redmi 7 section
