Sun Cellular Launches 0.facebook.com, a Free Way to Access Facebook® on Your Mobile Phone
0.facebook.com is lightweight and optimized for speed; Sun Cellular’s standard data charges do not apply for site
MANILA, Philippines and PALO ALTO, Calif. – June 2010 – Sun Cellular announced the launch of 0.facebook.com. Sun Cellular is now offering their customers free mobile browsing on the new 0.facebook.com site. By sponsoring 0.facebook.com, Sun Cellular is enabling their customers to stay connected through Facebook with their friends and family from any mobile Web browser using WAP as an access point without incurring any data charges.
Facebook’s 0.facebook.com site is optimized for speed – it is a new faster, lightweight version of Facebook’s mobile site m.facebook.com. The site does not have graphics or photos. Photos posted on Facebook are only one click away from 0.facebook.com. To view a photo a person only needs to click on a link to the photo and they will be prompted that they are leaving 0.facebook.com. Standard data charges of PhP 10/30 minutes will apply when a person leaves 0.facebook.com to view photos.
“The introduction of this new and exciting collaboration with Facebook is in line with Sun’s continuing campaign to provide value added services to both our prepaid and postpaid subscribers who value the importance of constantly being in touch with family and friends all over the world through a social service. 0.facebook.com is consistent with our reputation and stature as the country’s most progressive telecom network with pioneering offerings (such as the revolutionary 24/7 Call and Text Unlimited ). It is true to Sun’s promise of making connectivity all-day, all-night long available, without limits,” said Mr. Francisco Araña III, Vice President for Product Development, International Services, Value Added Services and Innovations.
“We are always looking to work with innovative companies to provide simple and fast mobile access to Facebook across the world,” said Henri Moissinac, Head of Mobile, Facebook. “Thanks to our collaboration with Sun Cellular, people will now be able to access Facebook for free through 0.facebook.com.”
