The UAE has some of the best mobile network infrastructure in the world, split between two operators — Etisalat (by e&) and du — both offering fast, reliable 4G and widespread 5G across Dubai, Abu Dhabi, Sharjah and the other emirates. Coverage is strong even in most desert resort areas, with only the most remote interior stretches seeing any drop-off.
One thing that catches a lot of travellers out: the UAE restricts internet voice and video calling on many popular apps. Standard voice and video calls on WhatsApp, FaceTime and Skype are typically blocked or unreliable on any connection in the UAE, regardless of which eSIM or SIM you're using — this is a country-wide restriction rather than something specific to any one provider. A small number of licensed calling apps are available locally if you need to make VoIP calls, but the simplest workaround for most travellers is to rely on regular phone calls (using your UK number's roaming or the eSIM's voice allowance, where included) rather than app-based calling.
The UAE isn't in the EU, so it isn't covered by UK providers' European roaming deals — check your specific plan's rest-of-world charges before you travel, since these can be high. An eSIM is a straightforward way to get reliable, affordable data for maps, messaging (text-based) and browsing throughout your trip.
Best eSIM for the UAE
For a short city break in Dubai or Abu Dhabi, a moderate data plan is usually enough given the strong 5G coverage. If you're travelling for work and need to hotspot a laptop, or you're combining a city stay with a desert resort, a larger or unlimited data plan makes more sense. Check whether the plan includes any voice minutes if you'll need to make calls, since — as above — you can't always rely on VoIP apps here. See our guide on how much mobile data you need for help sizing a plan, and compare options by price per GB rather than the cheapest headline figure.
UAE eSIM FAQs
Can I use WhatsApp or FaceTime calls with a UAE eSIM?
Voice and video calls on apps like WhatsApp, FaceTime and Skype are generally blocked or unreliable across all networks in the UAE, not just on eSIMs — this is a nationwide restriction rather than a provider issue. Text-based messaging on these apps still works fine; for calls, plan to use regular phone minutes or a licensed local VoIP app instead.
Does my UK phone work in the UAE without an eSIM?
Yes, your phone and UK SIM will work for calls and texts as normal. Data roaming charges depend on your UK provider's rest-of-world policy for the UAE, which is worth checking before you travel since it's outside the EU roaming zone.
Is an eSIM cheaper than roaming with my UK provider in the UAE?
Usually, yes. UAE roaming rates from UK providers are often high, so a local eSIM data plan tends to be significantly cheaper for any meaningful data use during your trip.
Can I use the eSIM alongside my UK SIM?
Yes. eSIM runs alongside your physical UK SIM on compatible phones, so you can keep your UK number active for calls and texts while using the UAE eSIM for data.
Do I need to activate my eSIM before I fly?
You can usually install the eSIM profile in advance on Wi-Fi and activate the data plan once you land — check your provider's specific instructions for automatic versus manual activation.
How much data do I need for a week in the UAE?
For typical sightseeing and city use — maps, messaging and social media — a moderate allowance covers a week comfortably. If you're working remotely or hotspotting a laptop, opt for a larger or unlimited plan given how much you'll rely on data instead of VoIP calling apps.
