Common Questions
The details worth knowing about your Sao Tome and Principe eSIM
Your eSIM connects to CST or Unitel STP, both of which offer 4G on bands B1 and B3. No 5G networks are available. Coverage is strongest on São Tomé island; Príncipe island has limited service.
If your phone does not support 4G bands B1 (2100 MHz) or B3 (1800 MHz), it will not get 4G on CST or Unitel STP. Most modern phones support these bands, but older or US-only models may not.
Yes, but mobile service on Príncipe is limited. Coverage is not as reliable as on São Tomé. If you spend most of your time on Príncipe, expect weaker signal or occasional dead zones.
No registration or ID is required to use an eSIM from the store. You simply install the eSIM before travel and activate on arrival. Local SIM cards may require registration, but this eSIM does not.
No. The eSIM only covers Sao Tome and Principe. Once you leave the country’s territory, the eSIM stops working. There is no roaming to neighbouring countries included.
