Apparently, the error affects Brazil, Mexico and also part of Europe, according to DownDetector. In contact with dnetc, a WhatsApp spokesman confirmed the bug. "We are aware that some people are having trouble signing up for WhatsApp accounts. We are working quickly for a correction."
The problem occurs when the user tries to install WhatsApp on a new phone. To register an account, the application needs to confirm the cell phone number and send an SMS with the validation code. However, instead of sending the confirmation message, the error "temporarily unavailable. Please try again in 5 minutes" appears on the screen.
