Billion Connect does not provide a Portugal eSIM that includes a phone number or SMS capability.
Only data‑only plans are available for Portugal, so travelers who need voice or text services will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Those apps generally work while connected, but some destinations may block or restrict certain services, so users should confirm that the apps they rely on are accessible in Portugal before purchasing a plan.
