They're functionally the same as normal SIM, instead it is stored in a secure location of the storage (which can survive factory reset). In a way, it makes it a bit more secure as a thief can't just yank out the SIM card to avoid being tracked (although it doesn't defeat a faraday bag) or take it out to use it in another phone.

The major function of a normal SIM is the ability to take it out of one device and put it into another one, effectively disconnecting my identity towards the network provider, from the handset. With eSIM, that doesn't exist, and if my phone breaks, it's unclear what happens.

To me, that's not secure, that's unsafe and insecure.

From a corporate device perspective it's an interesting evolution though, since we can remotely provision an eSIM through our mobile device management platform. No SIM to handle from the user point of view, and they can't take it out.

that doesn't exist

Well fwiw, the post we're commenting on is about that now existing.

the ability to take it out of one device and put it into another one, effectively disconnecting my identity towards the network provider, from the handset

Unless you think that taking a SIM out of a phone means that the phone is no longer connected to you, which isn't the case at all. A phone's IMEI is sent along with the SIM data as part of the initial handshake to make a mobile connection, your carrier knows the make, model and serial number of every phone you've ever put your SIM card in. The police in most countries make them keep track of which cell towers that combo of IMEI and SIM connect to and at what times. There's no privacy in using a mobile network you pay a bill for.

that's not secure

Obviously this isn't the be all and end all of security, but an eSIM slightly improves device security because a thief would be unable to remove it and disable any theft tracking measures which require network access. (Yes I know about EM shielded bags, but most thieves are opportunists)

The only real advantage of a physical SIM is that if you smash your phone up, you can walk into a shop and put it into a new phone without needing an internet connection first. If I smash my phone up, I need a WiFi network to hook my new phone up to the network. On the flip side, if I get robbed abroad, the process is the same. With a physical SIM it's gonna get sent to my home address.

So can I move my sim to an iPhone? Or a non google android?

[–] [email protected] 2 points 10 months ago

It seems to support transfer between Google and Samsung devices on the latest OS according to the article.

Given that, if it doesn't work with non-google/non-samsung devices today, I'd expect it to in the future as that's obviously the goal for this.

Funnily enough about iPhones, I don't think they even have a physical SIM slot anymore in some markets. So unless they have a transfer feature I'm unaware of, you're gonna spend a minute logging into your network's account screen and scan a new QR code, like you can with any eSIM phone today.
