WhatsApp™ Talk Unsaved Contacts av icetbr

Usage
Press the phone button, input the phone number and hit ENTER. This will reload the current page, opening a chat window to the unsaved phone number.

Why

I use mainly WhatsApp™ on my notebook. This allows me to quickly message many services to requests budgets, or to check wether they provide what I need.
It does the same thing online link generators like create.wa do, but without leaving the WhatsApp™ web interface. It calls WhatsApp™ API to contact an unlisted phone number.
