After 3 years of a basically unusable (as a phone, since 2G went away) Librem 5 under AT&T, I switched to a short-term Mint plan a few days ago. My settings are exactly as above, and VoLTE is enabled with the BM818 tool. However, I cannot make or receive calls. When trying to make a call, the outgoing call screen pops up but the call is instantly ended. There’s no indication of any kind on the L5 of an incoming or missed call, and on the phone I call it from I hear no rings and get, after 3 seconds, a “Please record your message …”. Meanwhile, texting appears to work okay; I can create, receive, reply between both phones, and receive texts from Mint when experimenting. I pull the Mint SIM out and place into my other phone and it works perfectly, without any settings changes.
Any suggestions or ideas? I’m leaning towards a modem problem; what do you all think? How do I buy a replacement modem from Purism?
Everything you just described is exactly what I experienced as well. Believe it or not though, it eventually resolved itself. I never did anything to fix the issue. I pretty much stopped trying to make phone calls for a while and just used the SMS feature, etc. Then one day I tried a phone call on a lark and it worked. Now it works fine, assuming I’ve got decent cell coverage.
Or, better, as a first step: Post the modem firmware version here and someone will tell you whether there is a later version. If there is then contact Purism Support. @tynerjohn

Sorry, didn’t know which, or if all, of these strings reported by bm818-tool to give.
Not unusual, except that you should have gotten some automated response. Also note that they don’t work over the weekend and it is still very early in the work day on the US west coast. (But it can take over a week to get response to email.)
A support technician responded to you on the same day as your email, then followed up yesterday. It appears that you may not be receiving email from the Support service desk. I’ve pinged the support team to connect with you to help resolve your issue.
After a frustrating hour or so last night at my desk trying and failing to get my L5 working after flashing the modem firmware, I walked out the door this morning to head to work. A few feet out of the garage I heard a tone or note from the phone in my pocket, and it’s been working (with Mint) since. Hopefully it will keep going.
It’s been my experience that sometimes, depending on the cell coverage and the phase of the moon, the modem silently freezes and I have to cycle the HKS to get connectivity via voice or SMS. If it is frozen and I do nothing with the HKS, but I travel into range of another tower, it will also start working.
I believe this sort of behavior is carrier agnostic – Mint Mobile is no better or worse AFAIKT.
Hopefully it will keep going.
