I followed this procedure for adding a 2nd SIM card WITH a micro-SD memory expansion in place:

I was successful with the Axon 10 Pro as well.
The only thing I did differently from the procedures linked above...
1.) Instead of CUTTING the SIM, I filed the edge down with a nail file to reduce the width (it didn't need much)
2.) I only needed to file ONE side (not both)
3.) I also filed the "lip" of the micro-SD card, to reduce the overall thickness of the combination *
("lip" = the edge farthest from the contacts, to facilitate removal with your fingernail, from a full-size SD adapter)
4.) I used Scotch double-sided cellophane tape, trimmed to the dimensions of the modified/hacked SIM card
Prior to starting, taped the full SIM2 in place and took a picture of the contacts, to help position the modified SIM properly,
when taping to the micro-SD, and to insure the orientation was right (and NOT 180 degrees off)
* The SIM/uSD "tray" went back into the phone with a BIT of added persuasion, and came back out again the same, without any damage.
(If you dare, you might try filing some more of the micro-SD housing prior to taping down the SIM)
The micro-SD and SIM combination also fit into a full-size SD adapter so I was able to read/write the memory card with my computer without having to disassemble the SIM from it.
Very pleased with the results - but of course, YMMV, and try this at your own risk.
