"The QR code is not recognized" when trying to add a valid eSIM

I am unable to add my eSIM to my Mudita Kompakt. When I try to scan the QR code, it does not scan. Typing in the number is no use either, it says “The QR code is not recognized.” The QR code did work on my old phone. eSIM capability was one of the prime selling points to me, as outside the Mudita Kompakt, there aren’t really any e-ink phones that allow the use of an eSIM.

@catscientist I’ve asked our team about this. Mudita Kompakt does support eSim & there are users on the FORUM who have eSims activated on their device.
I’m waiting to hear back from the team as to what could be happening in your case.

@catscientist Do you have the input the activation code manually? Many carriers provide QR code, but unfortunately it doesn’t always work out of the box.

@urszula I actually did try to manually input the activation code, and it was not recognized.

I had a similar issue and ended up taking it to an EE store to sort. Turned out the issue was on my iPhone that i moved from and a fairly common issue when moving from iPhone to Android. Can’t remember the exact problem but they were able to sort it in moments.

For a little more clarification, this is moving a silent.link eSIM from my Google Pixel to the Mudita Kompakt. So there’s really minimal customer support. So I just put the eSIM back on my Pixel. Then I got in touch with my VOIP provider directly and was able to get a physical SIM from them. I have seen from the forums that eSIM support is a little shaky in the US anyway, so maybe the physical SIM will actually work better.

@catscientist Technically, with Mudita Kompakt, there is no such thing as moving eSIM - this is always a unique new identifier, it just has the same mobile phone number. In some cases, this requires contacting your carrier to reissue the eSIM profile, since the transfer systems aren’t standardized. If you were just trying to use the same eSIM profile from your Pixel phone to Mudita Kompakt please note that one eSIM profile can only be active on one device at a time.
Your carrier, silent.link eSIM is not mainstream, so, I’m not sure how it would work with them.

That is very interesting, about moving the eSIM. What I did was deactivate the eSIM on the Pixel, then scan it again, which is what they said to do. I did not ask if they would reissue the eSIM, though. It actually may be the case that

silent.link

is optimised for the Pixel, since a lot of the people who are going to use their service are privacy-focused, and de-Googling the Pixel is a very popular thing to do. So this may be a good thing for the very privacy-conscious to know about. But, on that front, it would probably also be interesting for someone to test a fresh
silent.link
eSIM in their Kompakt, and see if it is just the process of moving it over that is broken, or if it is actually their eSIMS at fault. I have not tried that, but might at a future date, just to see if it works.

I do expect that, if there is a greater move to the Kompakt over privacy concerns, there will be more users trying to use a

silent.link

eSIM, and they will be very disappointed if it doesn’t work. But, as I said, I’ve got no problem trying a physical SIM in it, as I’ve seen fewer problems with that in the forums. I see this as a product that is still relatively new, so there are going to be hiccups. But I’m also very happy that the Kompakt is still in development, and that the engineers are very responsive to customer concerns. That is something that is very rare in tech–even in the FOSS world.

Not sure if that helps at all, this is from their website:


I’m not yet into eSim but it looks interesting.

Yes, I have the Data.Plus plan. It really is pretty amazing, by the way. Using the data when I’m out, and Wifi when available, is incredibly economical. That’s one of the reasons I signed up. But, again, it’s eSIM only, so it’s useless if the phone can’t scan the QR code.

Just did this process in Canada, was very seamless I have to say I was worried. I switched from a 19 dollar 500mb data unlimited call and text plan, to fizz mobile, where I get a gig of data, unlimited calls and texts for 17 bux

Hi, I have the same problem as OP - I’m trying to activate an Airalo sim card, that I’ve bought on another device. Neither QR not code is working…

Have you managed to find a solution yet?

I’m not very familiar with eSims, so I’ve asked our team for tips. Are you transferring from an iPhone? Or another Android?

I bought it on iPhone, but wanted to activate it on Kompakt.

In the end, I got a refund from Airalo and I’ll buy a physical SIM card.

That’s probably why
iPhone → Android is usually a bit more work.
Apple makes eSIM transfers within its own ecosystem very smooth.
When you leave that ecosystem, the eSIM can’t be “handed off” automatically.
So instead of a device-to-device transfer, you usually have to re-activate the eSIM on Android.
How painful this is depends on your carrier

Even though the e-sim was brand new and never activated on the iphone? Welp, that’s unfortunate.

Unfortunately that’s how the cookie crumbles. You might want to reach out to your network provider and see if you can get them to transfer it.
