G-Cash, in the Philippines, was the first mobile based money transfer platform. It was launched in October 2004, a year before M-Pesa.
There have been many attempts to replicate M-Pesa's extraordinary success. M-Pesa in Kenya is a significant outlier in the mobile money space.
[Edit: assumed M-Pesa founding date of 2007 in wikipedia was when M-Pesa launched. It actually launched pilot in Oct 2005. Exactly one year after Philippines system]
