Help! No data Service


I have been having issues for the last few days with getting calls in and out. But once I restarted my phone it worked. I did a chat today and they had me go through many steps and eventually they had me go through a "trouble with E SIM" process. No I have NO calls in or out. No text. Nothing. I was told that it was backlogged and that it could be 24 hours or more. This is my ONLY phone - work, personal and otherwise. I saw other threads about this, but they were from a long time ago. Help please!!! I just had surgery - I have no way of connecting to anyone and WiFi calling isn't working.
