Bordersim does not offer any Kosovo eSIM plans that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from Bordersim for use in Kosovo. While VoIP services such as WhatsApp, Telegram, and iMessage can generally be used over a data connection to make calls and send messages, the availability of these apps can vary, so users should check that the services they rely on are accessible in Kosovo before buying a data‑only plan.
