Any OS for Pinephone have call capability?

[quixote]

I gather a call was received, but not sent yet?, using pastmarketOS. I think you can also send txts on pmOS?

Is that right? Do any of the available OSes (also Ubuntu Touch, LuneOS, Sailfish) have two-way call and/or txt capability? I get the impression the answer is no, but I don't know why it feels like that. Finding actual info is really hard! (Maybe just for me, but there it is.)

Also, pmOS has mobile data working. So if I'm using Signal, for instance, which uses data instead of the cellphone company, will the calls work?

Thanks to anyone who knows the answers or where to look for them!
