Keeping its promise, Saudi Arabian government is now ready to block WhatsApp

Right now, Skype is still operational in Saudi Arabia and services that have previously complied with the government like BlackBerry Messenger are still up and running too. There are still a number of other instant messaging apps available (for now), so if by chance you are affected by this, check out our recent survey of messaging applications for ideas.
Unlike Viber, who is a relative small fry compared to WhatsApp and Skype, a ban on WhatsApp will prove to be a major inconvenience. WhatsApp is one of the few applications out there that has gone all-in across all the major and minor mobile platforms out there, making it accessible to just about everyone whether they had an iOS, Android, Symbian, S40, BlackBerry or Windows Phone device. Such accessibility has made WhatsApp a leading messaging platform, processing over 20 billion messages a day.
Now that Ramadan has begun, a suspension is all but certain at this point.
