I have been having trouble transfering my physical sim card from iPhone 12 pro to esim for iPhone 16 pro. I have made 4 phone calls in total and went in store twice and it never got resolved. Last phone call the tech support said they have filed an IT ticket and will give me a call back within 24 hours, and it never happened. I have tried emailing him (the guy who helped me and left me his email) and scheduling a phone call with him, never had and response nor call back. I have gotten my phone for more than 2 weeks now and I'm enough of the trouble. If it doesn't get solved tomorrow, I will switch to a different carrier.
