GulfData does not provide an eSIM with a phone number or SMS capability for Greenland. Only data‑only plans are offered, so travelers using GulfData will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text communication. While these apps typically work over the data connection, some destinations may block or restrict specific services, so travelers are advised to confirm that the apps they intend to use are accessible in Greenland before purchasing a plan.
