Preguntas frecuentes
Will data still work when I go over to Principe?+
It works in Santo Antonio and the larger villages, but along the southern coast, on the forest trails and at the beaches you reach by boat, you can be out of range for long stretches. Save your maps, your domestic flight details and your accommodation's number to the device before you take the small plane over from Sao Tome, and fix pickup times while you still have signal rather than assuming you can call from the other end.
Do I need Portuguese to get around on my own?+
You do not need to speak it, but you should carry a translation app. Outside hotels and tour operators, English does not go far, and agreeing a car price, asking directions or ordering in a small restaurant usually ends with you holding the screen out for the other person to read. Download the offline Portuguese pack too, because the places where you most need it are often exactly the places where the signal is weakest.
How do I get between the two islands, and what should I prepare?+
Most people fly: a small aircraft between Sao Tome and Principe takes about 35 minutes. Boats do run, but the schedule is unreliable and the crossing takes far longer. Guesthouses and the domestic airline often confirm by message or email rather than through a full online system, so screenshot every confirmation and keep it on the device, and leave slack in your plans because domestic hops can shift with the weather.
When does a Sao Tome and Principe eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
