eSIM not compatible with iphone

Hello everyone. Seeking help from experts and anyone who knows anything about this issue. So, I was using NTC eSIM on my iPhone 16 pro max for five months. Recently I had to add office sim which is Ncell esim to the phone. While attempting to add the Ncell sim, the error "This eSim is not compatible with this iPhone. Please contact your carrier." showed up. They generated a different eSIM. Same error again. They asked me to consult with Apple service center. Phone was checked, no issues there. They just reset my network settings and told me to update to latest version of ios. I did that and tried to add the Ncell sim. Same error again. Again at the Ncell center they suggested to remove the NTC sim and try adding the Ncell sim. I thought it wouldnt be a big issue and told them to try that. Deleted the NTC sim and tried adding the Ncell one. Same error. Now while trying to add the NTC sim back, the phone wouldn't take the sim. It showed the same error message. Today I went to NTC office where they generated a new eSIM and guess what? Same freaking error message shows up. Now my phone doesn't have any sim. Phone is not carrier locked, shows EID, has latest ios. I don't know what to do. So, if anyone knows anything about this issue and a solution please help ya girl out. I am freaking out rn.
