I’ve bought a 30 day eSIM for testing and successfully downloaded a profile.
After a reboot the phone was able to use it like a normal SIM card.
Thank you again for providing the binary!
Now I have 30 days to write a SIM-Manager app before the card runs out 
I tried with a Zoweetek ZW-12026-1 that I had for reading DNIe (you need the large card that SIMs usually come with as an adapter and also a USB-A to USB-C adapter to connect it to your cell phone) and also with the one sold on the 9eSIM website that directly supports nanoSIM and comes with USB-C and a USB-A adapter for use on a PC. With the driver binder you can use the phone’s SIM reader.
Great! I was able to test it with https://www.firsty.app/es, which offers a “free” service, and it also worked well, in case anyone wants to test it without having to purchase a service.
you can get a free esim profile anytime on ‘better roaming’
Thank you. I think I will try everything with the internal reader first and then order the one from their page and add support for it in January.
I pushed an initial version to OpenRepos today.
Good job I bought an esim on the web for Morocco. but failed to download it. On Xperia 10 v. It’s an esim for the holidays I would try in another country. The next time
if I understood correctly the app can be installed on a 10 III
I gave my Xperia 10 V away, so I can’t test whether it also works with the internal eSIM chip.
The Xperia 10 III has no built-in eSIM chip, so you have to use an external eSIM adapter.
I’ve tested it on the Xperia 10 III with this one:
I tried OpenRepos SimPro to manually download Eskimo eSIM Ahora que has recibido tu tarjeta 9esim, regálate algunos datos gratis - 9eSIM (We all know about the problems with the Xperia 10 V camera in Sailfish not working.), but I get an error:
From command-line I can dowload it fine:

Then I can see them correctly in SimPro. To activate it, it works fine from the edit menu, but it doesn’t activate from the drop-down menu.
Download and activation should be fixed in version 0.2.
I’ve tested it with two new manually added profiles, it seems to work fine now.
Out of curiosity, does the 9esim adapter work as on the 2nd sim slot? So that you could have your main sim at slot 1 and esim adapter at slot 2 which you could then get plan when you go abroad etc?
Yes, it does. I have one in my second SIM slot of an Xperia 10 III right now.
Amazing to hear! Have to do same kind of setup for the Jolla phone!
@Juanro49 I don’t have an external card reader yet, but should you have time to DM me some examples of how the lpac output looks like (preferably without piping through a beautifier) I could try to implement support for external readers anyway.
I guess the profile messages will be the same once a card is detected but I would like to see how things like driver apdu or chip info etc. look like without the reader, with the reader but no card present, with the reader and card, etc. to be able to safely detect it.
The information displayed by lpac with the pcsc driver is the same as with gbinder (except that for pcsc there is an additional command, “lpac driver apdu list” to list the connected readers). The only difference is the errors displayed, which are specific to the pcsc library and are documented here: pcsc-lite: ErrorCodes .
Here are some examples:

So, if I understand this correctly, there is no need to manually probe and select the specific external reader, and lpac will automatically use whichever reader has a card installed?
That means we could implement a simple logic along the following lines:
This would not allow for manual reader selection, but I doubt the added complexity would justify implementing that. It’s running on a phone, so very few people will have a USB reader permanently connected. If one is found, SimPro can reasonably assume it is meant to be used. If not present, the internal slot will be used.
That’s also probably far easier for users to handle than having to fiddle with software settings just to switch readers.
Plugging in or unplugging a USB dongle seems much more convenient.
This is only necessary when connecting multiple readers (using a USB-C hub for example), which should not happen under normal conditions since, in theory, people will only connect one external reader. I only tested it to see how the reader selection is made (in case you have free time in the future and want to add an “expert mode” where you can configure more parameters such as manually selecting the driver to use, a specific reader, etc.).
By default, lpac automatically uses the first reader it detects (the one in position 0), so if only one is connected, manual selection is not necessary.
I think the logic you propose is solid, as it’s simple and doesn’t require excessive modification of the current code.
Thank you, that’s perfect.
I rather know all the details and make an informed decision.
Also, who knows if there won’t be any requests for an “expert mode” in the future, so it’s good to have all the traces already.
Some of us are overly curious and like to try lots of things 
This has raised a question for me, which is how gbinder would work on dual SIM devices with two physical SIM cards that support eSIM (or when Jolla enables the eSIM chip on compatible phones such as the Xperia 10 V, allowing users to have the native eSIM chip and a physical SIM card with eSIM support). Will lpac be able to detect both slots? Since gbinder does not have the option that pcsc has to use one or the other in case it detects several. I think that will be a question for the lpac developers 
I asked myself this very same question earlier today. I’m so tempted to but another 9eSIM card that I don’t need just to satisfy my curiosity
