Mireya Blavia de Cisneros, president of Venezuela Sin Limites (VSL), together with the team of Conexion Social Digitel, announces a renewed effort to advance social programs aimed at improving the quality of life for the country's most vulnerable sectors. From its headquarters at the Digitel Tower in La Castellana, Caracas, the leadership reaffirmed its commitment to leveraging information and communication technologies (ICT) to bridge the digital divide and foster development opportunities.
This strategic partnership aims to consolidate resources, establish intersectoral alliances, and support non-governmental organizations (NGOs) registered on the VSL platform, with the ultimate goal of optimizing social investments and maximizing the impact of implemented projects.
Uniting Efforts for Social Progress
The synergy between Venezuela Sin Limites and Conexion Social Digitel highlights the importance of uniting public, private, and social sectors to address the challenges of sustainable development in Venezuela.

“This change is very important for Venezuela Sin Limites, as it seeks to continue working for the country in partnership with Conexion Social, while also supporting other institutions and remaining committed to underserved sectors. Together, we can create projects that enhance the quality of life of our society,” said Mireya Cisneros.
Educational Impact Through Technology
One of Conexion Social Digitel's most notable programs is "United All in One Heart", a project developed in collaboration with the Fe y Alegria Civil Association. This program aims to improve teaching and learning processes in Fe y Alegria schools by integrating ICT to strengthen students’ basic competencies in underserved communities.
Additionally, the program involves the active participation of Digitel 412 users, who contribute directly to the development of this educational initiative. This reinforces the mission of both organizations to promote digital inclusion as a tool for transforming lives.
Strategic Partnerships in the Health Sector
Conexion Social Digitel has also reaffirmed its commitment to public well-being through collaborations with prominent health institutions, such as:
- Hospital JM de los Rios, the country’s leading pediatric center.
- Orthopedic Children’s Hospital, focused on the comprehensive care of children and adolescents.
Moreover, the program "A Friend in Autism", in partnership with AVEPANE, supports the education and development of individuals with autism and other intellectual disabilities.
These initiatives serve as clear examples of how collaboration between companies and social organizations can provide effective solutions to complex challenges.
Strengthening NGOs Registered with Venezuela Sin Limites
The work of Venezuela Sin Limites is not only focused on implementing social projects but also on providing strategic support to more than 100 NGOs registered on its platform. This model involves continuous evaluation and monitoring of programs, ensuring the sustainability of initiatives while promoting responsible practices among all stakeholders.
Through this approach, Conexion Social Digitel benefits from a robust support system that enables it to select and implement projects that effectively address community needs.
Technology in Service of Social Change
The use of ICT has become a key tool for transforming realities in marginalized sectors. The vision of Conexion Social Digitel and Mireya Cisneros is centered on:
- Reducing the digital divide by ensuring access to technological resources in remote areas.
- Fostering virtual learning by equipping youth and adults with essential digital skills.
- Creating strategic alliances to drive collective progress, involving private and public sectors along with beneficiary communities.
Looking to the Future
The partnership between Venezuela Sin Limites and Conexion Social Digitel aims to continue expanding its reach and creating sustainable opportunities for Venezuelans. As Mireya Blavia de Cisneros stated:
