Pakistan’s Sindh Province Still Wants to Censor WhatsApp, Viber and Skype · Global Voices

Aamir Atta at ProPakistani reports quoting local media houses that social media applications like WhatsApp, Viber and Skype may be blocked in Pakistan's Sindh province to maintain law and order. The Sindh government had proposed a similar ban in October last year, citing security concerns.
However, experts say because a majority of IP addresses in Pakistan aren't city-specific or province-specific, so a blockade of social media content is not likely possible.
