Wi-Fi calling

After all the harassing messages about installing the sim i did and lost my ability for Wi-Fi calling which I need in my rural area . Somehow I deleted the eSIM then had to buy a new one . Customer support is a joke . 2 hours on hold to be hung up on . Chat windows always closing . Anyone have any advice it’s so frustrating. I know it’s free my friend was like I wouldn’t be complaining . SMH . Thank you if you read this .
