aloSIM does not provide an eSIM with a phone number or SMS capability for the Balkans. Only data‑only plans are available from this provider, so travelers will not receive a local phone number or the ability to send and receive SMS directly.
If callers require voice or messaging, they can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or services, so it is advisable to confirm that the chosen VoIP options work in the specific Balkan country before purchasing a plan.
