I understand that it may be problematic sometimes but this was very smooth. I didn’t even say anything.
A: what’s your number for the whatsapp group Me: I don’t have whatsapp because of facebook. B: ok, we have to use signal then A: ok
And that was it. Life can be very easy sometimes
SMS is still the dominant message format in some countries
But you are already on Signal.
Also I live in a country where SMS is very common
