Questions people ask
What travellers ask about eSIMs in São Tomé & Príncipe.
How do I install an eSIM for São Tomé & Príncipe?
After you buy a plan, the provider sends you a QR code by email or in their app. On an iPhone, open Settings, then Mobile Service, then Add eSIM. On Android, open Settings, then Network and internet, then SIMs. Scan the code while you are still at home on Wi-Fi, then switch the eSIM on for mobile data when you land.
Will an eSIM work in São Tomé & Príncipe?
Yes, as long as your phone supports eSIM and is not locked to your home carrier. The plans we list for São Tomé & Príncipe connect to local networks there. Coverage in cities is usually good; if you are heading somewhere remote, check which network the plan uses before you buy.
Can I use the eSIM as a hotspot?
Most travel eSIMs let you share data with a laptop or a friend's phone through a hotspot. A few providers block or limit it, so read the plan details if you need it. Anything you use over the hotspot comes out of the same data allowance.
Will I get a phone number?
Most travel eSIMs are data only: you get mobile internet but no local number. You can still call and message through WhatsApp, FaceTime or similar apps. If you need a number, tick Phone number in the plan filters to see the plans that include one. Your home SIM can stay on for texts such as bank codes.
