WHY THIS ROUTE MATTERS
Portugal is home to over half of all Santomean emigrants. Shared language, deep colonial history, and ongoing economic ties make this the single most important international calling corridor for Sao Tome and Principe.
With 18,219 to 19,778 Santomeans living in Portugal — representing 51.9% of the entire emigrant population — regular phone calls are the lifeline connecting families across the Atlantic. Parents in São Tomé keep in touch with children and grandchildren who have settled in Lisbon and beyond.
Many young Santomeans travel to Portugal for university education, drawn by the shared Portuguese language and established academic pathways. Families call frequently to check on their progress, coordinate financial support, and maintain emotional connections across the distance.
Portugal is Sao Tome and Principe's top import partner at $77.9 million in 2022, and the islands export $2.28 million to Portugal. Business calls between the two countries coordinate trade logistics, supply chains, and investment across this dominant commercial relationship.

COMMON HURDLES
International calling between small island nations and Europe comes with some unique challenges. Here's what callers on this route typically encounter — and how Sayfone helps.
International calls from Sao Tome and Principe to Portugal through traditional telecom operators can be expensive — a significant burden for families who depend on regular communication to coordinate remittances and stay connected with loved ones.
As one of Africa's smallest nations, Sao Tome and Principe has more limited telecommunications infrastructure compared to larger markets. This can sometimes affect call quality and availability through conventional phone networks.
Sao Tome and Principe operates on GMT (UTC+0) year-round, while Portugal follows WET (UTC+0) in winter but shifts to WEST (UTC+1) during summer months. This one-hour seasonal difference can catch callers off guard when scheduling calls.
Navigating exit codes, country codes (+351 for Portugal), and the 9-digit Portuguese numbering system can be confusing — especially distinguishing between landline prefixes (starting with 2) and mobile prefixes (starting with 9). Sayfone handles the formatting for you.
