WonderConnect does not offer an eSIM for El Salvador that includes a phone number or SMS capability; only data‑only plans are available from this provider. Travelers looking for voice or text services will need to use internet‑based solutions.
VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for calls and messages, but some destinations may block or restrict access to specific apps. It is advisable to confirm that the messaging or calling apps you rely on work in El Salvador before purchasing a WonderConnect plan.
