Well, the thing about the number is that I only give that out to friends and family that I know won't bug me all the time π€·ββοΈπ But also, in a way, I would say that using Messenger is definitely a *little* bit more secure than using SMS, considering the fact that SMS is completely unencrypted, whereas Messenger does encrypt in transit and is now partially end-to-end encrypted.
It's not ideal either way, but unlike a criminal tapping a cell tower, Meta can only do so much with my data in a legal way. So yeah, at the end of the day, if I can get a person using Signal instead of Meta's chat apps, that's great, but I will still take WhatsApp or Messenger over SMS.
