Car no longer has cell service

so my car was recently in a wreck. Body shop replaced the front bumper and sensors. Brought it to the dealership to get “re calibrated” and then the car lost cell service and car-net connection. I brought it in, the tech came out and showed me that the voice recognition. Is working, I showed him that the cell service indicator on the infotainment screen is missing and I opened my car net app showed him it hasn’t updated since the calibration. He said there was a blown fuse when they brought it in.. whatever that means, but that I might need to call car net.. but I was like either way, the car isn’t showing there’s any cellular connection.
Is there something that I might tell them to check for the cell connection? @VW TECHNICIAN maybe you could suggest what to say?

If they have no clue what you want to tell them....ask them to operate app....and if this is not working they are responsible to get this fixed and call car-net.
And yes there is a way with ODIS to check for cellular modem.
Voice recognition requires internet to work.
thank you for the quick response! I appreciate you!

So they said they initiated a VTA case? They. Allied the Bosch helpline and I need to “wait 24 hours. If issue persists customer would need to call 833-982-2048 for mobile concerns or the car net service helpline.” They say they’ve called as well and can’t figure it out. I have an OBDEleven, there is a secure onboard communication fault U14FE00 signature inspection failed, not sure if that means anything. I also noticed in long coding remote update is disabled. I just don’t want to change anything and mess anything up. Live data is showing that the data connection is active but the lte antenna signal is 0%. But alas they’re saying everything is fine. I’m sitting in my car just trying to figure a few thing out. It might be worth mentioning that voice recognition IS working though even though the 4G is gone.
Don't you think that DustID is talking about the 4G service provided by VW, which is totally separate and has nothing to do with the optional Verizon service? I never signed on for Verizon internet, but the 4G continues going on 5 months since delivery.
I am indeed talking about the service provided by VW, specifically car-net hasn’t updated since the “calibration”. It’s odd that the voice commands are working but now car net still isn’t working. For example I had it push notify when climate started/stopped same with charging. But none of the services work any longer.
update: it’s working, yesterday around 3:15p I was sitting in the car opened OBDEleven, went to telematics, changed mode to programming (just to see if I could see anything in there) and boom the dashboard lit up “emergency sos not available service vehicle” holy moly, now I’ve done it, and I haven’t even changed anything! So I change it back to vw diag mode, error went away (programming must just shut the comms off momentarily which is why the warning triggered?) anyway, when I went back diag mode, I was freaked out, so I made an SOS call, told the rep this was a test call and to verify if the signal is working, she said it was and she’s able ti see the vehicle info. Hang up the SOS call and the 4G symbol appears on the infotainment screen.

called carnet to verify they can see the car, they said it was offline but it came back online around 3:15 [around the time that warning popped up] Comms we’re working properly etc. opened car-net app and everything’s back to normal. So either A) it’s a coincidence and it rectified itself or B) somehow with the entering the wrong mode on OBD11 may have caused the module to “reset/reboot” and caused the refresh. Either way I’m happy that it’s working again, and I vow to never go back into programming mode 🤣 my stomach fell out when I saw that error 😬 .
