The service I’m using removed its Russian endpoints shortly after the Ukraine conflict broke out.
I neither know nor care if they did so of their own volition or were forced to do so: either reason is a huge red flag NATO flag against being able to trust them.
Actually, I wonder if I can use a phone number of one of my relatives in China, while geolocated in Canada. Like, is it geolocked by IP address on top of needing the right area code?
