If the modem is certified with carriers, why won’t they activate SIMs?
#1
You give a carrier or MVNO your IMEI, where the first 8 digits are a TAC that identifies the EG25-G, and the next six digits are just some sort of serial number (I think), and then a checksum digit, and rather than saying “Oh, the Quectel EG25-G! A fine piece of hardware! It’s been certified by the carrier, has a VoLTE profile, etc., so you’re all set, and enjoy your service!”, they say “Sorry, we can’t help you.” — so most people having to activate their SIMs in other phones.

What am I not understanding?

And is the situation likely to improve in some way over time, or is this just life for PinePhoners?

I think the secret is to find a MVNO that doesn't care about your IMEI. I activated on Tracfone with just the SIM card number and my ZIP code.

I do not know if the Quectel-EG25-G is 'carrier certified'  or perhaps 'FCC certified'......

But as @ThrillGates  points out some carriers are very easy to sign-up with,  and some are not. 

Have you tried multiple carriers, or tried different methods, perhaps if you have a particular carrier
you want to use and you cannot register online,   try using a different portal,   or if possible go to their
retail store..?

Just trying to change my sim card for an 'existing  AT&T PrePaid account'  has been hours & hours spent with
no success what so ever.

While signing up for new service from AT&T through TracFone was done in a few minutes online.
Simple Mobile for T-Mobile service is extremely 'simple'  as well....

I looked at some Quectel documentation and it showed certification for the US carriers (as of a year ago or so, I believe, with T-Mobile still in progress at that point), and Deutsche Telekom and some others.  But I don’t know a lot about the world of telecom, so I’m trying to understand what’s happening behind the Yes or No. What scares them off.
 
I can see that, as you’re saying, from the practical user perspective, it’s a process of being patient and maybe having to go through a few. And that if they will just send you a SIM and activate you, the phone can and the software can or soon will make the necessities work.
PS The forum is barely working at the moment; apologies if this ends up multiple-posting.

For the sake of completeness, I looked up the Quectel EG25G page and it lists

Deutsche Telekom/ Verizon/ AT&T/ Sprint/ U.S. Cellular/ Telus/ T-Mobile*/ Rogers*
