M-PESA International Money Transfer (IMT) is an innovative way to send from abroad to someone in Kenya. The money is sent directly in to the Receiver’s Mobile phone, to the M-PESA Account, and can then be used in various ways. The money transfer is received close to instantly (time of an SMS text message). Both the Sender & Receiver are sent a confirmation SMS text message from M-PESA.
On March 31st 2011, Western Union and Safaricom announced the global expansion of their international mobile money transfer service. The service was previously offered by Western Union and Safaricom between the UK and Kenya via 12,000 Western Union Agent locations and westernunion.co.uk.

The service will allow people to send funds from more than 80,000 Western Union Agent locations in 45 countries and territories directly to Safaricom M-PESA subscribers in Kenya.
