Demystifying ESIM Technology [video]

For who wonders about the waving cat: These are used a lot at hacker conferences to check if the cams are still working (and not frozen). Shenanigans on the network are of course common at these events :) So they are put on the stages while nothing is on.<p>This was a big success and it turned out to be a bit of a mascotte :P They&#x27;ve become a permanent fixture now.

My master&#x27;s thesis from 2008 [0] gives some insight into the early design and strategic considerations (from a Nokia perspective) behind eSIM technology, in case anyone&#x27;s curious.<p>[0] <a href="http:&#x2F;&#x2F;www2.imm.dtu.dk&#x2F;pubdb&#x2F;edoc&#x2F;imm6812.pdf" rel="nofollow noreferrer">http:&#x2F;&#x2F;www2.imm.dtu.dk&#x2F;pubdb&#x2F;edoc&#x2F;imm6812.pdf</a>

Any idea how one can get hands on consumer-profile eUICC cards (or chips)? I&#x27;ve wanted to play around with eSIM (and perhaps use it for travel purposes), but don&#x27;t want to upgrade my phone just yet.<p>Found this one, but it&#x27;s for testing only: <a href="https:&#x2F;&#x2F;www.smartjac.biz&#x2F;esim-subscription-management&#x2F;consumer-device-test-euicc-for-rsp-testing-remote-sim-provisioning" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.smartjac.biz&#x2F;esim-subscription-management&#x2F;consum...</a>

I&#x27;ve had a great experience with eSIMs these past few days during a trip to Europe (coming from the US). It&#x27;s so convenient to be able to arrive at a city and use airport wifi to download a mobile data package for a few bucks. The process is slightly clunky but not bad at all.

For those with multiple phones, how easy is switching back and forth?

Fun fact: Singapore doesn&#x27;t support eSIM at all. Very strange, given that that country is relatively progressive when it comes to tech.

Anything from Harald Welte (LaF0rge) is awesome. He&#x27;s the world&#x27;s best GSM &#x2F; Phone hacker &#x2F; explainer

Why did they change ccc to be at the same time as defcon instead of end of year?

Esim is a death for featured phones.

We really dodged a bullet on eSIM. The implementation could have really sucked if the carriers controlled it from the start. Apple do a lot of dumb shit but they set a really high bar for an eSIM implementation for others to match.
