Check if my number is used on WhatsApp, without using WhatsApp?
Lately when I forced to login to FaceBook they will sent a WhatsApp message to my phone number, even though I don't use WhatsApp. I'd like to see if there is really an account with my number. I tried going to the web client but it seems to be requiring to pair with a device app.
So yeah the person said it told them there wasn't an account for me and it sent me an SMS inviting me to join. But then they said the message they sent showed the blue double checkmark indicating the message had been seen. 😕 So I loaded the app on an old phone with no other apps or anything on it, and it registered my number without any fuss. So I guess Meta was put out a good psych game. But it's weird that the message was read before I setup the app.
