MeSIM does not offer any eSIM plan for Puerto Rico that provides a phone number or SMS capability. Travelers who purchase an eSIM from MeSIM for Puerto Rico will receive a data‑only plan and will not be able to place or receive standard voice calls or send SMS through the local network.
Without a local phone number, callers commonly rely on internet‑based messaging and voice services. Over a data connection, apps such as WhatsApp, Telegram, and iMessage can typically be used for communication, but these services are not guaranteed to work in all circumstances; some destinations may block or restrict specific VoIP applications. Travelers should verify that the communication apps they rely on are accessible in Puerto Rico before purchasing a plan.
