B523 and 3rd party SIMs

Hi guys,
I cannot find any information regarding B523 supporting 3rd party SIM cards.
From what I see there’s On-module MFF2 Particle SIM but not a word regaring
3rd party SIMs physical nor eSIMs. So what are the options here?


The B523 can only be used with the Particle SIM/MVNO.

The B Series (B402, B523), E Series (E310, E402), and Tracker SoM (T402, T523) do not support a programmable eSIM or an external SIM for a 3rd-party SIM card.
