MyTravel eSIM does not provide an El Salvador eSIM that includes a phone number or SMS capability. The provider’s plans for El Salvador are strictly data‑only. Travelers who need to make calls or send text messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so users should check that the apps they rely on are accessible in El Salvador before purchasing a plan.
