International mobile remittance

International mobile remittance (also known as international mobile airtime recharge / international top-up / top-up credit) is a remittance transfer service which allows a person in one country to securely and electronically transfer or top-up mobile credit to another mobile belonging to a family member or friend abroad. The top-up can happen through various payment mechanisms. The sender selects the country, mobile network, number of the recipient, mobile air time amount, and makes the transfer. The mobile air time is credited to the recipient instantly.
