SITANGKAI, TAWI-TAWI — On the map of the Philippines, Sitangkai appears as little more than a small dot at the country's southernmost province. Yet beyond its size lies a vibrant municipality known as the Seaweed Capital of the Philippines and the "Venice of the South," where homes, schools, and communities are connected by waterways instead of roads.

Classified as a Geographically Isolated and Disadvantaged Area (GIDA), Sitangkai's location has long made access to essential services a challenge. But today, despite the distance, its communities are increasingly connected—not only to one another, but also to the rest of the world.

Through the Connectivity, Capability, and Resiliency through Free Wi-Fi for All (CoRe FW4A) project, a partnership initiative by the United Nations Development Programme (UNDP) and the Department of Information and Communications Technology (DICT) in partnership with the Local Government Unit of Sitangkai, reliable internet is helping bridge the digital divide and bringing new opportunities to one of the country's most remote municipalities.

The impact is perhaps most evident at the municipality's only Rural Health Unit (RHU), which serves approximately 60,000 residents across nine barangays.

For Haifa S. Yusoph, who has worked as a nurse at the RHU for the past four years, connectivity has transformed not only how health workers do their jobs, but also how communities receive healthcare.

Before reliable internet reached the RHU, routine administrative work came with extraordinary challenges.

Without internet access and with unreliable mobile signal, submitting reports to government agencies meant traveling nearly two hours by fast craft to Bongao, the provincial capital.

The journey was not only expensive and time-consuming—it could also be dangerous. Traveling by lancha, the primary mode of public transportation between Sitangkai and Bongao, takes six to eight hours, depending on sea conditions, and costs around PHP 500 per trip. During rough weather, the long journey across open waters posed additional risks for health workers who had no choice but to travel to submit routine reports."When the sea was rough, traveling wasn't always safe," Haifa recalled. "But we had no choice because reports had to be submitted."

Today, what once took an entire day can be completed in minutes.

Reliable internet has streamlined reporting, allowing health workers to spend less time traveling and more time caring for patients.

Connectivity has also changed the way healthcare reaches the community.

Every day, Haifa and her colleagues conduct health education sessions for residents across Sitangkai's nine barangays. With internet access, they can now search for updated medical information, educational materials, and visual resources that make complex health topics easier to understand.

"When we conduct health education, we can now search for additional materials online," Haifa said. "For example, we can show testimonials from mothers about family planning. These real-life stories help people better understand the information and encourage informed decisions."

Visual learning tools have made health teachings more engaging, helping communities better understand topics ranging from maternal health to disease prevention.

Reliable connectivity is also enabling residents to access the DICT–mWell telemedicine platform through their mobile phones. The service provides free teleconsultations with licensed doctors, allowing patients to seek medical advice and receive health guidance without leaving the municipality.

For a community separated by the sea, this means healthcare is no longer limited by geography.

The benefits of connectivity extend beyond the health sector.

According to Haifa, more residents are now able to stay informed about current events, access online information, and make use of digital services that improve everyday life.

"The internet has helped people become more aware of what's happening around them," she shared. "With better connectivity, more people can access information and learn new things."

For communities like Sitangkai, internet access is more than simply going online. It connects people to education, government services, healthcare, and opportunities that were once difficult to reach because of geography.

It also demonstrates that digital transformation is most meaningful when it reaches those who have historically been left behind.

The CoRe FW4A project forms part of the Philippine government's efforts to expand reliable internet access in public places, particularly in geographically isolated and disadvantaged communities.

Through its partnership with DICT and local governments, UNDP supports efforts to ensure that connectivity translates into tangible development outcomes—strengthening public services, improving access to information, and creating opportunities for communities to thrive in an increasingly digital world.

In Sitangkai, the impact of connectivity is measured not only by stronger internet signals, but by faster public services, more effective healthcare, and communities that are better informed and better connected.

For Haifa, the difference is simple.

What once required crossing the sea can now be accomplished with an internet connection.

For Sitangkai, a small dot on the map has become a powerful reminder that no community is too remote to be part of the Philippines' digital future.

Because meaningful connectivity is not just about technology—it is about ensuring that everyone, everywhere, has access to the opportunities and services they need to live healthier, more connected, and more resilient lives.
