yaySIM does not provide an Aruba eSIM that includes a local phone number or the ability to send or receive SMS. Their offerings for Aruba are data‑only plans, so travelers will not have a native mobile number for voice or messaging.
If callers and text messaging are needed, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection. Travelers should verify that these apps are accessible in Aruba, because some destinations may block or restrict certain services.
