I am having S21 FE Exynos version and from last month I witnessed that network connection of Sim 1 becoming freezes in maximum time. I am having Airtel sim in Sim tray 1. Before 1 month this type of problem was not there. Whether it is problem of my phone or network issue because I am facing this in all areas where ever I am going. The problem is now becoming frequent and last for few seconds. If I have done any call at that situation, internet connection becoming restored.
My dear reset network setting of both Sim one by one and than reset all settings of your's device in general management settings also Flight ✈️ mode on n off one time also restart your's device one time without any Sim in slots and interchange your's Sim into slots. Thanks.
