TO HELP those in disaster-struck Japan stay in touch with their friends and family, Skype is giving out a free ¥80 (about S$1.25) credit voucher to each of their Japanese customers. With the voucher, they can make a call of more than 25 minutes to a land-line phone in Japan (as well as to some other countries, including China and the United States), or send text messages directly from Skype. The vouchers, which are being distributed to Skype's customers in Japan via email, expire on April 17. Last week, Skype also made their pay-per-minute Internet access service free at WiFi hotspots throughout Japan. This story is only available online.
