esimzon does not offer any Tunisian eSIM plans that include a phone number or SMS capability; the provider only offers data‑only plans. Travelers using esimzon in Tunisia can still access VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but this capability is not guaranteed because some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to confirm that the apps you rely on remain available in Tunisia before purchasing a plan.
