These simply didn't have market penetration and network effects in the Indias and Indonesias of the world. Probably did not have a dominant network even in the US. Maybe they we a bit ahead of their time of easy internet availability anytime. The other innovation was WhatsApp used phone numbers already stored on phone address book as identifiers, allowing rapid user onboarding and spread without much effort by the user. Again maybe these others happened before the smartphone revolution making this possible |
