      You get a QR code for the new sim, go into the eSIM manager on the phone, and scan it

        I don’t want a “new sim”, I want my old one, which doesn’t exist anymore since it was virtual and only existed in my now broken previous phone. How does it work in that situation?

          Call your carrier or go into a store and they move it over. If your phone is broken you’ll kinda be SOL since there’s no way to authenticate the move.

            Exactly. What a shitty anti-feature. Your answer proves that the people saying that “eSIMs are functionally the same as normal SIM” are full of absolute shit.

                Not the person you asked but I have a couple of sims by different providers that I swap between phones/sim routers when I need to make calls or use data from that carrier. Popping the sim into an old device and configuring whatever I need is super convenient.

                Keeping my number. Are you saying that I can immediately, online, get my existing number connected to a different handset? If I can’t, then that’s why I want to transfer the physical SIM.

                  Now I can’t answer for other regions, but with my carrier here in Norway I can sign in to their website and authenticate with the government ID system (bankid) and generate a new esim and get the QR code. Takes about a minute total.

                  I’m personally more for physical sim cards as swapping it into a new phone or swapping in a traveler datasim etc is just something I prefer to have physically.

                  That being said, I use esim for my phone number, and then swap in travel sims for data with my physical sim slot, works really well when you travel a lot.

                  Yes, that’s exactly how it works

                    What prevents someone else from doing that at any point, taking over my number? Is the only authentication a simple login to the mobile provider’s website?
