+* Purism developer Sebastian Krsyszkowiak [says](https://forums.puri.sm/t/questions-about-dogwood-and-phone-calls/10156/23) this is caused because the Librem 5 doesn't support VoLTE:

+> There’s no VoLTE, so it drops to 3G when in call. This would mean that there’s no 3G reception where you live, so it makes it drop all the way to 2G (but data should still work, although much slower - unless there’s something wrong carrier side of course).
