MoodSIM does not offer an eSIM plan with a local phone number or SMS capability for travelers in Uruguay. Their available plans are data‑only, so if a local number or the ability to send or receive text messages is required, users must rely on internet‑based messaging services. Popular VoIP applications such as WhatsApp, Telegram, or iMessage can typically be used over the data connection, although some destinations may block or restrict access to certain apps or VoIP services, so travelers should confirm that the services they rely on are accessible in Uruguay before purchasing.
