Esimzon does not offer eSIM plans for Bosnia and Herzegovina that include a phone number or SMS capability. The available plans are data‑only and do not provide voice or text messaging services. Travelers who need to make calls or send messages can use VoIP or messaging apps such as WhatsApp, Telegram, or iMessage over the data connection; some destinations may block or restrict specific apps or VoIP services, so it is advisable to verify that the apps relied upon are accessible in Bosnia and Herzegovina before purchasing.
