MicroEsim does not provide an El Salvador eSIM that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for this destination, so travelers will not receive a local number or the ability to send or receive text messages directly through the SIM.
Those who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict or block access to specific apps or services, so travelers should confirm that the apps they rely on are available in El Salvador before purchasing a data‑only plan.
