According to TechCrunch:
Mig33 is a downloadable mobile social networking application with a bunch of utilities mixed in. Users can not only do the usual profiles and friending, but also includes VoIP calls, instant messaging, e-mail, text messaging, picture sharing. Long distance calls can be made by using pre-paid Mig33 minutes. They have an affiliate program for selling minutes and have even launched a calling card business in South Africa. Users have been signing on for more than a total of 2 million sessions per day, sending more than 45 million messages each day, and share more than a million pictures a month.
Mig33 has users in 200 countries and has an increasing customer base of 9 million + users.
Hmmm, I did not know that so many people accessed social networks via cell phones, so this is enlightening. I guess it makes sense though–not everyone has an iPhone or a laptop, but most folks have cell phones.
