Your WhatsApp and FaceTime calls keep working
This is the thing worth knowing before you travel. The UAE restricts voice and video calling over WhatsApp, FaceTime and Skype, and anyone using a local UAE SIM finds those calls simply will not connect. Our eSIM connects through an international roaming route rather than a local subscription, and calling keeps working on it. For most visitors that is the whole reason to arrive with an eSIM already installed rather than buying a SIM at the airport, because the alternative is landing in Dubai and discovering you cannot call home the way you normally would.
