Globe Telecom of the Philippines last Friday launched DUO, an unlimited mobile and landline calls bundle available to pre-paid users in Metro Manila. It also offers the DUO service in service after unveiling it there on 25 May. Globe claims that DUO is the first unlimited mobile and landline call service offered anywhere in the world. The 2-in-1 package uses a single SIM and enables the user to make unlimited calls from the Globe network to any fixed line number and from any landline to Globe, as well as to and from any DUO post-paid mobile subscriber - provided they are all within the same area code. People signing up to DUO’s add-on pre-paid offer receive a special pre-paid SIM pack for PHP45 (USD0.94) allowing them to benefit from unlimited mobile and landline calling within Metro Manila and Cebu for five days for PHP125 and PHP350 for 14 days.
