Facing SIM network issue on my Galaxy M21 phone. Not receiving good internet connection or call quality.  In family we are using same carrier, but only I am getting issue while using internet or call. Samsung should look into this issue. M series have this same issue since launch time. Kindly release any update to solve this.
