"This is not the typical technical method in which the Chinese government censors something," said Nadim Kobeissi, an applied cryptographer at Symbolic Software.
Kobeissi said the latest WhatsApp ban indicates that Chinese censors have developed software which is interfering with text messages.
He said WhatsApp message transfers initially started facing disruptions on September 20 and were 'comprehensively' blocked on September 25.
Why did China block WhatsApp?
Importantly, the WhatsApp ban coincides with the 19th National Congress of the Chinese Communist Party.
Despite the WhatsApp ban, services provided by US tech companies such as Microsoft's Skype continue to run.
Unlike WhatsApp, Skype doesn't allow end-to-end encryption, possibly why Chinese censors haven't blocked it.
However, Apple's FaceTime is allowed in China despite having end-to-end encryption.
