Apart from the general countries like China or India (where dual-sim is standard), it’s also interesting for other countries. I don’t want to miss the option to use one SIM for work and the other privately. I can also deactivate the work sim after work and never have to carry around 2 phones.
i hope purism crew will make it possible
some devices use the microsd spot for the other sim slot, if is possible should be nice to have it, is a really good feature for alot of countries
