ByteSIM does not provide an eSIM plan for Lithuania that includes a local phone number or SMS capability. Travelers who need data access can purchase a data-only eSIM from ByteSIM, but will not receive a phone number for voice calls or SMS. For voice or text communication, users can rely on over‑the‑top services such as WhatsApp, Telegram, iMessage and other VoIP apps that operate over the data connection, although some destinations may block or restrict certain services, so it is advisable to confirm whether the preferred apps are usable in Lithuania before purchasing.
