Roamless eSIM Plans for Sao Tome and Principe

Unitel STP is the sole operator Roamless names for Sao Tome and Principe, so its published network choice is settled before you pick a plan; the practical differences within this small catalogue are the allowance and validity. Roamless lists the service as up to 4G, a stated ceiling rather than a promise about the signal everywhere. It has not published where traffic breaks out, so the resulting IP location and delay to local services are unknown. Top-up is supported, so an exhausted plan can be topped up rather than immediately rebought.
