Hi Brad, I read somewhere that the Modem in the “Librem 5” at present, that a person has to choose from for Australia (the European one of the BM818), will work with 3G too. This by the info from the Modem’s Website of the 3G and 4G Bands it supports (below), does suggest by the up-todate Info below the modem’s specs; about the Bands each Carrier in Australia use, that the phone will work quite well, for the 3 Carriers, with 3G and 4G! Have a look through, and check that please.
There is only the 4G Band (B28) missing from the modem for it to fully support all Australian frequences used. I think I’ve read that B28 is not used in many places? (Check your area though, when you do get 4G).
BM818-E1: (I’m pretty sure that E1 stands for European)
