This usually means the PRI and modem images aren't compatible.  Try
these AT commands to get a bit more info:

AT!ENTERCND="A710"

then

AT!GOBIIMPREF?

And then I think that'll give us enough to see what the images you have
onboard are, and whether they are compatible with each other.  This
info is also available via the qmicli --dms-list-stored-images and --
dms-get-firmware-preference commands.
