S21 plus didn't get stronger wifi network and don't show as much like other phone available networks and also wifi range very poor and data on sim internet very much slower than others phones
Bro some sim data dont work great on samsung.. and some Work great. Like on my phone telenor data is rubbish while zong runs great.. on the other side. My Oppo phone runs telenor as fast as zong on my samsung at the same time
