rvw (755107) writes "Using a prepaid phone without credit, you can take over another WhatsApp account. During installation WhatsApp asks you to enter your mobile phone number and sends out an SMS to verify the number. Because the SMS is not sent, but is accessible, you can send the SMS via a mobile service, using another phone number. The account is then linked to your phone, and will be disabled on the other phone."

Submission Text Formatting Tips

We support a small subset of HTML, namely these tags:

  • br
  • a
  • ol
  • ul
  • li
  • dl
  • dt
  • dd
  • em
  • strong
  • tt
  • blockquote

"ecode" can be used for code snippets, for example:
