if you figure out direct contact with Option, I am happy to help you
with getting this all sorted. oFono utilizes the modems at their maximum
and thus we can get you detailed AT command traces for almost every
single problem we have faced with other modem manufactures. Besides
voice call handling, I think we have the Option modem fully supported

The Telit modem is indeed not small. At least the ones that I have seen
so far.

And most likely Infineon (actually Intel now) might not wanna give you a
good deal or small quantities for the 6260 or similar modems. Have you
tried to ask?
