LEAWOOD, KANSAS—April 14, 2003—Euronet Worldwide, Inc. (Nasdaq: EEFT), a leading electronic payments provider, today announced the Citibank Indonesia launch of Euronet Mobile Recharge service, which enables consumers to replenish prepaid airtime directly to their prepaid mobile phone. This launch includes payment connections for the four major Indonesian mobile operators. Satelindo, Telkomsel, Excelcomindo are available now and IM3 is expected to launch in the second quarter 2003.

Euronet provides this Indonesian transaction switching service through a joint venture called Euronet Sigma Nusantara (ESN), which processes the mobile transactions at ESN's local data center in Jakarta. Euronet began mobile transaction switching in Indonesia last year, offering connectivity between Satelindo, with 2.4 million customers, and three local banks. The addition of mobile operators Telkomsel, Excelcomindo and IM3 enables consumers to add prepaid airtime for any Indonesian mobile operator. Telkomsel has 5.0 million customers, Excelcomindo 1.6 million customers and IM3 0.4 million customers. According to a report by Paul Budde Communication Pty Ltd, a global independent telecommunications research and consultancy company, by the end of 2002, around 80% of the customers of the country's leading mobile operator, Telkomsel, were using prepaid. Of all the new subscriptions, prepaid services are running at more than 80%. This Euronet Mobile Recharge project marks the first time for an electronic distribution method supported by all Indonesian mobile operators.

By selecting Euronet's Mobile Recharge service, Citibank has enabled approximately 1.4 million active cardholders to perform recharge transactions from their mobile phones. As the largest bank issuing credit cards in Indonesia, Citibank is initiating a large-scale promotional campaign to launch the service to its cardholders. The cardholders can register for the service through Citibank, which authorizes transactions through its online connections to the ESN data center. ESN acts as the centralized application provider and intermediary, performing daily settlement and reconciliation among all participants.

"In our preliminary soft launch in February, Citibank customers found that recharging their prepaid mobile accounts via this electronic method is very quick and easy, and it is the ultimate in convenience" said Th. Wiryawan, Citibank marketing communication and business development director. "The service applies to all the major mobile prepaid cards, enables the top-up directly from the mobile phone and charges the customer's credit card account; thus, making the service even more valuable to our customers. The initial response to this service has been overwhelmingly positive, our customers are registering for the service and usage is high."

With simple short message service (SMS) commands on the handset, customers can top up airtime on their prepaid mobile phones – any time, any place. After the transaction is authorized and processed, the customer's credit card accounts will be debited for the purchase amount. The customer's mobile phones then receive an SMS message from the mobile operator confirming that the transaction is successful.

"Citibank is a progressive bank that understands the value of offering convenient payment methods to its customers," said Daniel R. Henry, Euronet president and COO. "The addition of all the Indonesian mobile operators is indicative of the shift mobile operators are making to electronic distribution everywhere, and Euronet is committed to providing comprehensive top-up solutions in the region and around the world."
