it is my first time trying to use a sim card since it is a new pc i just bought ! and i'm not sure how to check if the sim slot is actually functional ; i tried dell support software to check for software updates and issues and some other external software but it didn't work  
Hi i tried installing a sim card on the sim slot though it is not showing on networks or any other place , i wounder do i have to install any software to use it or is that an issue on this new version of windows 11 , thank you
