just curious on this response on the other question, when you say “if you want to increase message sending speed, you should add more sim cards/device”

my question is, if I use 2 or more sim to send messages to increse message sendiing speed as you say, does the contacts will receive a message from different numbers or just 1 number?

Because it’s useless to speed up the sending speed if the receiver will receive message in different numbers. There are pros and cons, and most cons for a company.
