WhatsApp and FaceTime voice and video calls are restricted on local UAE networks, but they usually work on a travel eSIM. That is because a travel eSIM routes your data internationally as a visitor, rather than through a local consumer plan. The eSIM is data-only, keeps your own number, and connects to one of the UAE's main 5G networks (Etisalat or du) where available.
Why local SIMs block these calls
In the UAE, internet voice and video calling over consumer mobile plans has long been limited. On a local SIM, apps like WhatsApp, FaceTime and Messenger will usually let you text and send voice notes, but voice and video calls can be blocked. This is how local consumer plans are provisioned; it is not a fault with your phone.
Why a travel eSIM is different
A travel eSIM connects through international roaming partners rather than as a local subscriber. In practice, that usually means WhatsApp and FaceTime calls work the same way they would when roaming on your home plan. Results can vary by app and network conditions, but for most visitors a travel eSIM is the most reliable way to keep calling and video-calling home from Dubai.
What it costs you in data
Calling home is light on data: a WhatsApp voice call is only 20 to 30 MB per hour, and even video is around 200 to 300 MB per hour. A week of daily calls, plus maps and messaging, fits easily in 10 to 15GB. Streaming and social scrolling are what add up, so size up if you do a lot of either.
Setting it up
Install the eSIM over WiFi before you fly. When you land at Dubai International (DXB), turn the eSIM line on, enable data roaming for it, and set it as your data line. Your home SIM stays in place for your own number, and hotspot is supported.
