Inserting a 5G SIM card into a 4G phone will work, but you won't benefit from 5G speeds. The phone will operate on its highest compatible network, which is 4G. This setup is practical if you plan to upgrade to a 5G phone later, as you won't need to change SIM cards again. However, for now, you will only experience the capabilities of 4G.
