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.
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.
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?
If SIM swapping is your concern, know that it is just as simple to do with physical SIMs. It's not like your phone number is hardcoded to that one card alone. The phone company can easily move your number around. Literally anything you'd want to do with a physical SIM you can do with an eSIM. Some very niche situations may be easier with a physical one but over all it's a much nicer experience with eSims
Literally anything you’d want to do with a physical SIM you can do with an eSIM.
No. There is no reason for you to blatantly LIE. It is NOT possible for the consumer to switch to using a borrowed or backup handset, when there is no physical token. How on earth do you think that contradicting actual reality is an argument?
Yes, it is possible. You use whatever the provider's method is to download an eSIM to that device. Usually it's logging into their app or calling their support to register the IMEI or whatever.
You trust your carrier to not give your number away today, right? Many providers allow a number migration code to be generated from their website, protected by just their authentication.
The fact that carriers have poor security today isn't an argument for discontinuing the part of the system that still allows the consumer to be in control. It's an argument against it.
I'm not actually saying they have poor security, authentication is authentication, you need to be able to trust your carrier regardless of if your SIM is physical or an eSIM. I'm saying the two approaches are essentially equivalent.
You're aware your provider can turn your current SIM into a piece of inert plastic via a migration access code. That's what I just described.
Whether it's physical or software, your carrier has 100% control. You cannot do anything your carrier doesn't want you to with it.
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.
