The UAE has some of the best mobile coverage anywhere — blanket 5G across Dubai and Abu Dhabi, strong signal in the desert and out to the east coast. There's one local quirk every visitor should know about before they travel, though: the UAE restricts VoIP calling on apps like WhatsApp and FaceTime. Your data, messaging and everything else work normally; it's only app-to-app voice and video calls that are limited. Here's how to plan around it, plus a realistic data budget.
The UAE regulates internet voice and video calling: WhatsApp, FaceTime, Messenger and Skype calls are commonly blocked, even though the apps' text and media messaging work fine. This catches travelers out, because elsewhere we tell you to call home over data for free. In the UAE, plan to call over your home line where you can, or use a licensed calling app — and know that a travel eSIM doesn't change this, since the restriction is at the country level, not the network's.
A travel eSIM gives you fast, cheap data in the UAE — but it can't bypass the country's VoIP rules. WhatsApp/FaceTime calling may not work regardless of which SIM or eSIM you use; messaging and data are unaffected.
Day-to-day use in the UAE is data-heavy: maps and ride-hailing (Careem, Uber), translation, and a lot of photos and video from the skyline, the desert and the malls. Streaming and social posting are the big drains, as ever.
| Trip | Suggested data |
|---|---|
| Long-weekend city break | 3–5 GB |
| 1 week | 5–8 GB |
| 2 weeks | 10–12 GB |
| + hotspot / heavy streaming | Unlimited |
Coverage rides the two tier-1 networks (Etisalat and du) with excellent 5G across the cities, the airports, and most tourist areas including desert resorts. You'll rarely lose signal; the main reason to download offline maps is a deep-desert safari, where it's wise anyway.
Install the eSIM before you fly, then set Zwitchy as your data line and enable Data Roaming for it on arrival — the step-by-step guide covers both platforms, and the compatibility checklist confirms your phone is ready. Keep your home SIM in (data roaming off) for bank codes — and, in the UAE, for the calls home that VoIP apps can't always make.
Sharing data with a laptop at a Dubai café? See the hotspot guide, and weigh plan sizes against what they cost. For most visitors, 5–8 GB a week is plenty.
