All PinePhones have basically the same hardware, but there have been some revisions of the mainboard to fix certain issues. Check out the wiki section about the PinePhone's hardware revisions. If you have the Ubports edition, you have v1.2 (which was followed by v1.2a and v1.2b). The modem is capable of VoLTE in any case.
