My Note 10 plus has poor network reception

it's not any modem issue it's an issue of network stability in software so try to reset network settings in reset options if it works than good either go to Samsung's service center and install a stable software from them it will make your device more stable
mark as solution if its work

DEAR FRIENDS,

I HAVE PURCHASED SAMSUNG M30S MOBILE.

THIS MOBILE SIGNAL RECEPTION IS VERY WEEK. CONFIRMLY I WILL BET SAMSUNG TECHNICAL PEOPLE ALSO WITH 100000/_ REGARDING SIGNAL RECEPTION IS WEAKER THAN OTHER MOBILES LIKE XIAOMI, REALME LIKE CHINESE MOBILES. DONT PURCHASE THIS MOBILES . THEY ARE PROVIDING THEIR ' EXYNOS ' WORST PERFORMING PROCESSORS. THIS IS REAL WHAT I AM TELLING . BELOW I HAVE GIVEN SIMPLE EXAMPLE FOR YOU.

FOR SAMSUNG S20 MOBILE , THEY ARE PROVIDING THEIR WORST 'EXYNOS' PROCESSORS IN INDIA , FOR THE SAME MOBILE IN AMERICA THEY ARE PROVIDING BEST SNAPDRAGON 865 PROCEESOR . EVEN THEIR KOREAN PEOPLE ALSO HATED THE SAMSUNG 'EXYNOS' PROCESSOR PERFORMANCE IN ' SAMSUNG S20 ' MOBILE.

AND THEIR SERVICE ALSO VERY WORST. TODAY I VISITED THEIR SERVICE CENTRE TO RECTIFY THE CHARGING PORT PROBLEM , HE TOLD THAT IT WILL TAKE ONE WEEK TO 10 DAYS TO RECTIFY THE PROBLEM . THIS IS A SMALL PROBLEM . I TOLD HIM TAKE THE COMPLAINT , AND GIVE MY MOBILE BACK , AFTER ONE WEEK I WILL COME AND I WILL GIVE THE MOBILE AND RECTIFY THE MOBILE WITH NEW PART . HE REFUSED FOR THE SAME . REGARDING THIS ALSO I CALLED THEIR CUSTOMER CARE , THEY ARE NOT ABLE TO TELL WHERE THE PART AVAILABLE TO THE NEAREST SERVICE CENTRE IN GUNTUR DISTRICT.

OTHER COMPANIES ARE DOING SMALL PROBLEMS WITH IN ONE DAY. BUT SAMSUNG IS TAKING 10 DAYS . THIS MUCH OF WORST THEY ARE DOING SERVICE.

THEY ARE RELEASING NUMBER OF MODELS WITH SAME PROCESSOR 'EXYNOS 9611' BUT NOT MAINTAINING PROPER SPARE PARTS AT THEIR SERVICE CENTERS . THEIR SERVICE CENTER PEOPLE ARE BEHAVING LIKE GAZITTED OFFICERS. FIRST OF ALL THIS IS THE MAIN PROBLEM WITH SAMSUNG.

thanks

Its not about modem issue it's about network issue. In india none of the networks are stable so you will face this issue everywhere. Contact your network operator.
