Find the best eSIM for São Tomé and Príncipe

São Tomé and Príncipe offers 7 travel eSIM providers and 28 prepaid data plans, so while the selection is somewhat limited, travelers can still find a plan that matches their needs.

Currently, there are no unlimited data eSIM plans available for São Tomé and Príncipe. Travelers should estimate their data usage based on anticipated activities such as browsing, social media, or streaming, and select a plan with a data allowance that comfortably covers these needs throughout their trip.

São Tomé and Príncipe is served by two primary Mobile Network Operators (MNOs):

• Companhia Santomense de Telecomunicações (CST): Established in 1990, CST is the state-owned telecommunications provider offering mobile voice and data services, including 2G, 3G, and, as of August 2023, 4G LTE coverage across the islands.

• Unitel São Tomé and Príncipe: A subsidiary of Angola-based Unitel International Holdings, Unitel began operations in 2014 and provides mobile voice and data services. In May 2023, Unitel launched the country's first commercial 4G LTE network.

Currently, São Tomé and Príncipe does not have any Mobile Virtual Network Operators (MVNOs).

Travel eSIM plans that include a phone number and support inbound and outbound voice calls and SMS are offered for São Tomé and Príncipe by Roamify and Orange Travel. The numbers that come with these plans use the international dialing code +33, which is the code for France; because +33 does not match São Tomé and Príncipe’s local code +239, the numbers are not local to the destination.

Both providers give 30‑day validity. Prices start around $25 and can go up to about $60. If a local number is required, travelers can still use data‑only eSIMs and rely on VoIP applications, though the availability of such services may vary and should be confirmed before purchase.
