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.

This country's connectivity row is currently low-confidence (small / island / single-operator / fast-changing market), so treat the carrier, band and 5G details as a starting point we are still verifying.
