Red Mobile, formerly ümobile and legally as Connectivity Unlimited Resource Enterprise, Inc. (CURE), was a wholly owned subsidiary of Smart Communications, the Philippines' largest mobile telecommunications company. When it was initially launched as ümobile, it used the CURE Universal Mobile Telecommunications System network. At that time, it offered its services through an invitation-based, ad-supported platform, catering to middle and upper-class subscribers between the ages of 15 and 35, devoting its services to that demographic. After re-branding, both the ad-supported revenue platform and invitation system were scrapped in favor of a more traditional marketing and revenue-generating approach. In March 2010, Red Mobile started promoting its unlimited service offerings. However, subscribers started reporting on online social networks that the CURE UMTS network has since been converted to a GSM network. It closed in July 2012.
