SIM/eSIM totally stopped working I tried everything

Hey, I really need help because my SIM / eSIM is completely broken and I’m honestly out of ideas.

It started with random SIM failures. At first I could fix it by restarting the phone or turning the line off and on, but after a few days it just stopped working completely.

I tried deleting all eSIMs, but even after erasing them they were still showing up. Then I did a full factory reset. Didn’t help. I reset it again using the Apple Devices app — still nothing.

After that reset I put my old SIM back in, but it still had no service at all. No signal, nothing worked, I couldn’t do anything. The phone was basically dead for mobile use.

I thought maybe the SIM itself was the problem, so I bought a brand-new physical SIM. Same result. Literally nothing changed.

As a last step I did a full DFU restore and set the phone up from scratch. Even after that, mobile service is still broken. I can open Mobile Services and I see the SIM there, but it’s turned off, shows no number, and when I tap on it the page is completely blank. There’s also no option to add a new eSIM anymore.

What’s weird is that I can see all the normal device info model, serial number, software versions, my Apple ID emails, everything so the phone clearly knows what it is. I just can’t activate or use any mobile service at all.

At this point I genuinely don’t know what to do. I’ve tried multiple SIMs, full resets, Apple Devices restore, and DFU, and nothing changes. I really need this to be escalated or properly checked because I’m completely stuck.
