Skyalo does not provide any Saint Martin eSIM plan that includes a phone number or SMS capability. All of Skyalo’s Saint Martin offerings are data‑only plans, meaning customers receive no local voice or text services through the eSIM.
Travelers who need to place calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but service availability depends on local restrictions. Therefore, users should verify that the VoIP apps they rely on work in Saint Martin before purchasing a Skyalo eSIM.
