With the High Technology System, we have several SMS Center operator numbers located in several of each Cellular Operator. Electronic credit will be able to top up the destination cell phone automatically. So you just have to wait and automatically the credit or PPOB will be filled by itself. Confirmation of success will be reported via SMS and via the web. On the Multipay web there is also a price list that is always up to date so that agents can find out price changes and the status of vouchers in Multipay.
