Kompakt VoLTE support among carriers

Technical Support

First of all, thank you, Mudita team, for launching Kompakt. It’s a unique device which presents nice balance between smart- and dumb-phone.

I’ve been using mine for about a week now but I can’t get VoLTE to work. I’m based in Poland and my carrier is nju mobile (Orange). My * # * # 4 6 3 6 # * # * menu reveals that my phone is “unregistered” in the IMS service despite the fact that I’m connected over LTE.

Digging into the topic a little bit, I found that Orange has a list of “approved” devices. I suspect that devices which are not on the list are banned from accessing VoLTE.

Now, my questions:

  1. Is there anything I can do to enable VoLTE on my Kompakt? If not, is it on Mudita Team’s roadmap to co-operate with Orange (and possibly other carriers) to get Kompakt approved for VoLTE?
  2. I wonder what is other user’s experience? Did you get VoLTE to work? If so, what is your carrier? I could consider switching if I knew which ones support VoLTE on Kompakt.

I’m really hoping to get VoLTE to work because otherwise the call quality is mediocre.

Have you tried enabling this in the ADVANCED settings under your Network Provider?

@urszula, thank you for your reply. Yes, I have this option enabled:

But whenever I call someone, the “LTE” icon in the top bar changes to 3G and I have very basic call quality.
From your photo I conclude you’ve got VoLTE to work in Play – is that right?

@szk Yes, I’ve got PLAY & I’ve really have not experienced any issues. In the last two months, I’ve traveled with it to Athens, Rome & Istanbul, and really great roaming EU coverage.

What other carriers are known to work with VoLTE on Kompakt (besides Play)? Is there a plan to support Orange? I think it’s one of the biggest carriers in PL.

@szk Our team has said that it does work on ORANGE (supports VoLTE)

It could be that it’s in an area that has limited coverage.
Not to knock down Orange- but I use to have them & whenever I traveled up north via A1 (the highway) I would have dead spots & limited connection. Once there was an accident & I had to get of the highway & go through some back roads & there were places where I had NO SERVICE. I switched after that.
