Stellar eSim does not offer an Ireland eSIM with a phone number and SMS capability. The provider only sells data‑only plans for Ireland, so users cannot make or receive traditional voice calls or SMS messages. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so users should verify that the apps they rely on work in Ireland before purchasing a plan.
