Talk:ESIM

Why was the factually correct and concisely written correction 1084227434 reverted?
MrOllie reverted edit https://en.wikipedia.org/w/index.php?title=ESIM&oldid=1084227434 ; sadly, that was rather well-written and factually correct. eSIM is a bunch of bits, eUICC is the hardware. The reversion edit says

"Distinction without a difference, and just confuses the article"

but this is the eSIM article and hence should strive to be factually correct about eSIM. And: There's a very significant distinction between a piece of hardware and the things on it.

I didn't want to start an edit war, so let's discuss, but also set a timeline: I revert this revision on Mon 2022-06-09 16:00UTC, if no discussion happens. --Marcusmueller ettus (talk) 09:51, 6 May 2022 (UTC)


 * This would be like writing 'The program, which is executed on the CPU which is mounted on a motherboard' on articles about any piece of software. It is a distinction that is wholly meaningless to our target audience and just serves to confuse them with another acronym that means nothing to them. We should not sacrifice readability to technical pedantry. MrOllie (talk) 11:53, 6 May 2022 (UTC)
 * The fact that eSIM is a piece of data that's being installed into a hardware platform is the defining feature of eSIM that makes it different from regular SIM cards. How can such distinction be meaningless?
 * Your analogy doesn't make sense. The article is currently saying something like "the program, which is permanently mounted on a motherboard" when it actually means "the hard drive, which is permanently mounted on a motherboard, containing the program". The program (eSIM) on that hard drive (eUICC) can be replaced even if the hard drive itself can't. 83.24.19.57 (talk) 12:04, 6 May 2022 (UTC)
 * The entire point is that the eSIM is something you download and swap, while the eUICC is the pice of hardware on your physical device to which that eSIM is installed.
 * If the eSIM was the physical chip, how could it be "provisioned remotely"?
 * Furthermore, you can have multiple eSIM installed on an eUICC concurrently. If you use the term eSIM to refer to the hardware, that doesn't work.  Nobody can remotely install another piece of hardware in your phone. Not even the NSA. HaraldWelte (talk) 19:22, 6 May 2022 (UTC)
 * I added the word 'hardware' in a few places to try to make the difference clear without getting bogged down in technical terms. MrOllie (talk) 22:26, 6 May 2022 (UTC)
 * Mr Ollie shall give up with his kid behaviour. I will search on how ban him... The fact that he tries to correct someone (Harald Welte) who has reverted the eSIM show his imcompetence. 109.28.232.2 (talk) 00:07, 7 May 2022 (UTC)
 * It seems
 * @Wikipedia
 * doesn't seem to care about factual corrections in technical articles. Guess I will stop fixing any mistakes now, if using correct technical terms to distinguish hardware (eUICC) from data (eSIM) is a "distinction without a difference"

 * If you say there is no difference between a PC or Windows ? I found it stupid even if it is well written and respect Wikipedia policy. That the same some persons here use the Wikipedia policies to talk like sh.. 109.28.232.2 (talk) 00:20, 7 May 2022 (UTC)
 * You just put a spam link back into the article. MrOllie (talk) 00:22, 7 May 2022 (UTC)

Samsung Devices
Why was my edit on Samsung support reverted? I own an unlocked S21 myself and dual SIM works fine when using both a physical SIM card and an eSIM profile. In the dialer/messaging app you can select which SIM you want to use before making a call or sending a text. You only have to reboot the device when switching from one eSIM profile to a different eSIM profile. 100.34.236.211 (talk) 13:07, 8 May 2022 (UTC)


 * The 109 IP editor apparently could not figure out how to edit the page properly and reverted them. I have put them back for you. MrOllie (talk) 13:11, 8 May 2022 (UTC)

Use of undefined acronyms
What is a "DTU"? None of the items listed on https://en.wikipedia.org/wiki/DTU make sense in this context and Google is likewise unhelpful. — Preceding unsigned comment added by 72.138.223.72 (talk) 02:00, 7 January 2023 (UTC)

China Esim
Chinese Apple Watch's can have esims, so saying Mainland China doesn't support it at all is incorrect. 37.252.95.107 (talk) 08:31, 6 October 2023 (UTC)
