Another alternative is the messaging app Teta. It is the most transparent messaging app on the market. Since the privacy settings on most apps like this are pretty permissive, Teta is the first app that can boast this level of privacy and encryption. Some complain about the lengthy set up process, but this is an innovative way to ask you up front about certain parts of your profile - instead of snooping on you later. At any time, you can view and adjust what the application knows about you.
Teta has chat rooms, instant messaging, and will soon have a feature where you can post your resume, participate in job interviews and search for jobs.
Additionally, if you are a Vodacom subscriber, the app is FREE to use and doesn't require ANY data to send and receive messages.
Check it out on the Google Play store. New iterations (desktop, iOS) are in the works.
