Now I’m less in a hurry to receive my Mudita Pure here in the USA. I’d prefer that Mudita resolve many of these problems before I get mine. 
Fortunately I’m on a T-Mobile-based MVNO. We shall see whether I will need a new SIM. I got my current SIM from the MVNO a year ago – through the mail, given that the MVNO has no bricks-&-mortar presence.
Regarding the problems that you listed, almost all seem to be software problems, so I am optimistic that the Pure can and will be what Mudita and Pure customers want it to be.
