Instabridge does not offer a Baltic eSIM plan that includes a phone number or SMS capability. Travelers using Instabridge in Baltic will receive a data‑only eSIM, and can rely on VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection. However, some destinations may block or restrict specific VoIP services, so users should confirm that the apps they need are accessible in Baltic before purchasing.
