Skyalo does not offer eSIM plans that include a phone number or SMS capability for Guinea‑Bissau. The provider’s selections for this country are limited to data‑only eSIMs, so travelers will not receive a local SIM card number or the ability to send or receive traditional SMS messages.
Instead, passengers can rely on internet‑based services such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection. These VoIP apps generally work in Guinea‑Bissau, but some destinations occasionally block or restrict certain applications, so it is advisable to verify that the apps you depend on are accessible in Guinea‑Bissau before completing a purchase.
