Its support comes in the form of K50,000 ($A23,000) cash and in-kind support valued at more than K130,000 ($A60,000) which includes the provision of mobile closed user group (CUG) services for the 11-day event and a toll-free number for the public can get more information about the event, how to register and where to buy tickets.
PNG WiB executive director Janet Sape welcomed the support of Digicel and said the event would foster networking and showcase the entrepreneurial spirit of women in the region.
"Digicel plays an important role in transforming our modern PNG society, enabling access to information and communication and its commitment to recognise the work PNG WiB is a partnership in the right direction," she said.
She also said the expo coincides with the Pacific Games to expose women to economic opportunities in the region, and invited other organisations to support women's empowerment in PNG.
Digicel's consumer head Khattar Fehmi commended Sape for her work and said empowering women was a "key driver for poverty alleviation" and improve the socio-economic outcome for families.
"As a business we believe that helping women to engage in business and economic activity build stronger families and communities and contribute to sustainable economic growth," he said.
"We are doing our part through corporate social responsibility to ensure that as Digicel grows, our community grows as well and women play an important role in nation building when they are welcomed, included and engaged in business.
"The support we are pledging today is more than just finance, it is a long-term relationship we are fostering, especially those in the informal sector through PNG WiB."
