Tested with Fairphone Checkup, except secondary microphone I do not notice an issue. It continues to connect to Japanese mobile carriers (KDDI and docomo) as well.
With secondary microphone, the phone creates echo feedback loop on both the updated version and the previous version (Reported here) and loudspeaker mode is barely usable.
