Sao Tome and Principe has two mobile network operators, CSTelecom and Unitel STP, offering 3G and 4G/LTE connectivity on bands B3 (1800 MHz) and B8 (900 MHz). A travel eSIM will work on any modern eSIM-compatible phone to connect to these networks, regardless of whether local eSIM support is available in-country.
Connectivity options are limited, and roaming rates tend to be expensive. A regional or global travel eSIM may prove more practical than roaming on your home plan, though coverage remains sparse outside the main towns of Sao Tome and other urban centres. Local eSIM availability is currently being verified. Travellers should confirm coverage in their intended destinations before departure, as network reach can be unreliable outside populated areas.

Compiled from public-record telecom facts (the MNO roster, commercially-launched 3G/4G/5G generations, deployed travel-relevant bands and local-eSIM support) and verified June 2026; see the source we compile this country from. Local-eSIM availability checked July 2026 against the major carriers' own pages. This country's connectivity row is low-confidence (small / island / single-operator / fast-changing market): some details could not be confirmed from official sources in our July 2026 check, so treat the carrier, band and 5G specifics as a starting point.
