If you're planning a trip, sooner or later you'll ask yourself the same question I did: how does internet in Dubai work and which option is truly worth it. The Emirates is a hyper-connected country, but it has a particularity that catches almost all tourists off guard: internet calls are restricted. Here I compare all the alternatives, without exaggeration.
How the network works in the Emirates
In the United Arab Emirates, there are two licensed operators: e& (formerly Etisalat) and du. That's it. Everything connected to a mobile network goes through one of these two, overseen by the TDRA, the telecommunications authority. This concentration explains two things: the technical quality is excellent, and the rules are very consistent.
Quick summary: in the Emirates, you have 4G and 5G almost everywhere, free Wi-Fi throughout Dubai, and several ways to connect. The difference between them is not in speed, but in price and whether you can make WhatsApp calls or not.
Coverage is among the best in the world. 5G reaches downtown Dubai, the Marina, Downtown, the metro (including tunnels), and large shopping malls. You won't miss anything in terms of speed.
The problem is not the quality of the signal, but what the network allows you to do with it. Both operators apply network-level filtering to voice and video calls over the internet. It doesn't matter if you have five bars of 5G: if your traffic goes through an Emirati network, certain calling apps won't work for you. This is the big nuance that changes the entire decision, which is why I dedicate two entire sections to it below.
The four options for connecting, compared
When you land in Dubai, you have exactly four paths: rely on your operator's roaming, survive on Wi-Fi, buy a local Emirati SIM, or have a travel eSIM activated from home. Each has its logic and suits a particular type of traveler.
| Option | Approximate price (7 days) | WhatsApp/FaceTime calls | When it's worth it |
|---|---|---|---|
| Your operator's roaming | From free (EU with package) to €60-100 or more | Usually yes (traffic routed externally) | If your plan includes the Emirates without surcharge |
| Wi-Fi only | €0 | Depends on the Wi-Fi; often blocked | Short and hotel-based trips, without much going out |
| Local SIM (e& or du) | €15-30 + passport and process | No (local network filtering) | Long stays or if you need an Emirati number |
| Travel eSIM | €8-20, activated before flying | Usually yes | Tourism, layovers, and those who want zero hassle |
My recommendation, and not to oversell it: for a tourist trip of 4 to 14 days, the winning combination is your own data plus hotel Wi-Fi. Your own data gives you autonomy on the street and—very importantly in the Emirates—it restores your internet calls. Wi-Fi is useful for downloading heavy things at night. If you want the full breakdown of prices versus your operator, I detail it in the comparison of eSIM vs. roaming.
Hotel, mall, and taxi Wi-Fi
It must be admitted: Dubai is probably the easiest city to find free Wi-Fi. Dubai Mall, Mall of the Emirates, the metro, airports, almost all cafes, and of course hotels offer open connections. The public network UAE Wi-Fi also covers public areas and beaches.
It sounds perfect, and for basic consumption, it is. But there are three catches before betting everything on Wi-Fi:
- Mandatory registration: many networks ask for an SMS verification. If you don't have data or a number that receives international SMS, you'll be locked out of the portal before you even enter.
- Discontinuous coverage: Wi-Fi doesn't help when you need it most, walking down the street with Google Maps open or waiting for a Careem.
- The same restrictions: public Wi-Fi also goes through an Emirati connection, so internet calls are usually blocked there too. This is the most common mistake: people assume that they can video call home from the hotel, only to find out they can't.
Wi-Fi is a good complement, never the main plan. And if you were thinking of renting a portable router, I'll save you time: in this comparison of eSIM vs. pocket Wi-Fi, I explain why that extra device, with its battery and deposit, no longer makes sense for a normal traveler.
The local Emirati SIM and the free tourist SIM
Here's some good news and some not-so-good news. The good news: after passing immigration control at Dubai airport, you can get a free tourist SIM. Both operators offer it, with different and very limited conditions:
- e& (Etisalat): you scan a QR code right after passing immigration and activate a tourist eSIM with about 10 GB valid for 24 hours, without removing your home SIM.
- du: distributes a free physical SIM at arrival counters with approximately 1 GB for 24 hours.
The fine print is that these gifts expire in one day and are a hook to get you to recharge a paid package. A real tourist package (one or two weeks with data and minutes) costs around 100-125 AED, about €25-30, and requires a passport, sometimes biometric scanning, and queuing at the counter. If you're traveling as a family, multiply the process per person.
And the big catch, the one nobody tells you at the counter: a local Emirati SIM connects to the internet via the Emirati network, so it inherits all the country's restrictions, including VoIP calls. You buy a perfect data card and still can't call via WhatsApp. The general analysis is in eSIM vs. local SIM.
Your operator's roaming: what it really costs
The Emirates is not in the European Union, so the "roaming like at home" rule does not apply. That's the most expensive misunderstanding I encounter. Many travelers assume their Spanish plan will work the same as in Lisbon or Berlin, and they get a surprise when they return home with the bill.
Spanish operators usually offer two models for the Emirates: a daily bundle for zone 2 or 3—from €3 to €12 per day—or, if you don't contract it, pay-per-use, which is where the triple-digit shocks come from. Ten days with an €8 daily bundle is €80 just for connection. I have broken down real rates in the guide on how much international roaming costs.
That said, roaming has a virtue that almost makes up for the price: your traffic is routed through your original operator and does not go through the Emirati APN, so WhatsApp calls usually continue to work. This is why some acquaintance might tell you "well, WhatsApp worked fine for me in Dubai": they were roaming and didn't know it.
The problem is that you pay a premium for that privilege when the same technical behavior can be achieved for a fraction of the cost.
VoIP call restrictions: WhatsApp and FaceTime
Let's get straight to the point, because this is the detail that changes your trip. In the Emirates, voice and video calls over the internet (what is known as VoIP) are regulated: only licensed operators and a handful of apps approved by the TDRA can offer this service within the country.
Translated into practice: on local networks, WhatsApp, FaceTime, Messenger, Telegram, or Instagram calls are usually blocked. Pay attention to the nuance, because it matters:
- WhatsApp is not prohibited. You can chat, send photos, audios, and videos normally.
- What is blocked is the real-time call, whether voice or video. The call button appears, but the phone rings without connecting, or it cuts off after a few seconds.
- FaceTime falls under the same restriction, as do video calls from most Western messaging apps.
- The approved apps are others: BOTIM, C'ME, or HiU Messenger. They work, but they require the other person to also install them, which turns a call to your mom into a project.
What throws people off is that the restriction doesn't depend on the country you're in, but on where your traffic is routed from. Filtering is applied to the local Emirati APN: if your data doesn't exit through there, there's nothing to filter. This is the loophole exploited by roaming and travel eSIMs, without breaking any laws.
Why a travel eSIM usually saves your calls
A travel eSIM is not an Emirati operator: it is a roaming profile. It connects to the e& or du antenna for signal, but your data goes to the internet through the provider's infrastructure, usually in Europe. This detail, which seems like boring engineering, has an enormous consequence.
Since the traffic does not cross the domestic Emirati APN, call filtering is not applied, and WhatsApp or FaceTime calls work as they would at home. It's the same mechanism as expensive roaming, but at eSIM prices. And you achieve this without removing your usual SIM: you leave your number active for bank SMS and data on your travel profile.
| Scenario | Where your traffic exits | WhatsApp calls |
|---|---|---|
| Local Emirati SIM | Local APN (e& / du) | Usually blocked |
| Hotel or mall Wi-Fi | Emirati provider | Usually blocked |
| Your operator's roaming | Your originating operator | Usually work (at a high price) |
| Travel eSIM | Provider's infrastructure, outside the country | Usually work |
I'll be honest: no serious provider guarantees 100% that a specific app will work, because network policies can change. What is documented, however, is that the restriction applies to domestic traffic and that roaming connections do not go through that filter. If you rely on calls, have BOTIM installed as a backup plan. And if you're not sure how this technology works, start with what an eSIM is.
Real coverage: Dubai, Abu Dhabi, desert, and Burj Khalifa
Coverage in the Emirates is outstanding, and you won't encounter unpleasant surprises in tourist areas. Still, there are nuances worth knowing:
- Dubai city: Solid 5G in Downtown, Marina, JBR, Deira, Business Bay, and Palm Jumeirah. The metro works with coverage even in underground sections.
- Burj Khalifa: Yes, there's signal at the top. On the 124th and 148th floors of the At the Top observation deck, mobile coverage works, and there's also Wi-Fi. What you will notice is saturation when the observation deck is full at sunset, the peak hour when everyone is uploading photos at once.
- Abu Dhabi: Coverage equivalent to Dubai in the city, the Corniche, the Sheikh Zayed Grand Mosque, Yas Island, and the Louvre.
- Dubai - Abu Dhabi Road (E11): Continuous coverage throughout the journey.
- Desert: In the usual safari camps of Al Lahbab or Al Marmoom, there's signal, although it sometimes drops to 4G or even slower between dunes. If you take a long excursion towards Liwa or the Rub' al Khali, there are areas without coverage. Download offline maps before you go.
A practical tip: in the desert, the biggest enemy is not the lack of network, but battery life. Extreme heat drains it, and a phone searching for signal consumes twice as much. Always carry a power bank.
How much data you need for your trip
The million-dollar question. My experience with destinations like the Emirates, where you spend all day using maps, translating menus, and taking photos, is that people buy too little for fear of spending too much. Here are real consumption figures:
| Usage | Approximate consumption |
|---|---|
| Google Maps (1 hour of navigation) | 5-10 MB |
| WhatsApp: chats and photos (1 day) | 20-50 MB |
| WhatsApp video call (10 min) | 50-100 MB |
| Instagram or TikTok (30 min of scrolling) | 250-500 MB |
| Upload 20 photos to the cloud | 80-150 MB |
| Netflix or YouTube (1 hour in HD) | 1-3 GB |
With these numbers, my rule is simple: estimate between 500 MB and 1 GB per day for normal tourist use (maps, messaging, social media, some video calls). A 7-day trip is well covered with 5 GB; if you record stories all the time, increase it to 10 GB.
And what you should not do under any circumstances is watch streaming series with mobile data: save that for hotel Wi-Fi, which in the Emirates is usually very good. If you want a specific plan recommendation by number of days, you can find it detailed in my specific guide on eSIM for Dubai.
Layovers in Dubai: connecting for just a few hours
Dubai is one of the largest hubs on the planet, and many people only pass through the Emirates on their way to Asia, Australia, or Africa. If your layover is 2 to 4 hours and you don't leave the airport, you have unlimited free Wi-Fi at DXB, which is more than enough: you connect, notify home, check your boarding gate, and fly.
Things change if your layover is long. With more than 8 hours, many people go into the city—the Emirates offers visa on arrival for Spanish citizens, and the metro connects the airport to Downtown in half an hour—and that's when you need data on the street. Contracting a local SIM for six hours of sightseeing is absurd: paperwork, queuing, and a package you won't get your money's worth from.
For layovers, my recommendation is to have data activated even before taking off from your home country. You land, turn on your phone, and you're already ordering a taxi while the rest of the passengers queue at the operator's counter. On a layover, time is the scarcest asset.
An important note: if you plan to use the wait to call home via WhatsApp, the airport Wi-Fi won't let you, because it goes through the Emirati network and inherits the restriction. With roaming data, that call usually goes through without a problem.
Frequently asked questions
Do WhatsApp calls work in Dubai?
On local Emirati networks, no. WhatsApp messages, audio, and photos work normally, but voice and video calls are network-restricted by TDRA regulation. With roaming data (a travel eSIM or your operator's roaming), traffic exits the country, and these calls usually work.
Is it illegal to use WhatsApp for calls in the Emirates?
Using WhatsApp is not illegal: the app is allowed and used daily throughout the country. What happens is that VoIP calls can only be offered by licensed operators, so local networks filter them. A roaming connection does not violate any rules: your traffic does not pass through a domestic Emirati network.
Which calling apps do work in the Emirates?
Those approved by the telecommunications authority: BOTIM, C'ME, and HiU Messenger. They work on local networks, but the person you're talking to also needs to install them. It's a valid plan B if you rely on an Emirati SIM.
Is the free tourist SIM at the airport worth it?
As a temporary fix, yes. e& offers about 10 GB valid for 24 hours and du around 1 GB. They are useful for the first few hours but expire in a day, and since they are local networks, they don't give you internet calls back.
How many GB do I need for a week in Dubai?
5 GB is more than enough for normal tourist use for seven days: maps, messaging, social media, and some video calls, counting between 500 MB and 1 GB daily. If you constantly record and upload videos, consider 10 GB. Save streaming for the hotel Wi-Fi.
Is there coverage in the desert and at the Burj Khalifa?
Yes, in both. At the Burj Khalifa observatory, there is mobile coverage and Wi-Fi, although the network gets congested at sunset. In the safari camps near Dubai, there is signal, sometimes only 4G. On deep routes towards Liwa, it might disappear: download offline maps.
Can I keep my Spanish number while using data in the Emirates?
Yes, and that's what I always do. With a compatible phone, you keep your usual SIM active only for calls and SMS (useful for bank codes) and use a second profile for data. However, deactivate mobile data on your home line to avoid charges.
Conclusion
The Emirates is a technically impeccable destination —5G everywhere, Wi-Fi even on the metro— with one catch: internet calls are restricted on local networks. You can have the best signal in the world and not be able to video call your family.
My recommendation is clear: get your data sorted from home with a roaming connection, use the hotel Wi-Fi for heavy use, and forget about queues and surprise bills. It's cheaper than roaming, faster than a local SIM, and it also gives you back the calls that Emirati networks take away.
If you want to get it ready before you fly, here's my eSIM for the United Arab Emirates: you activate it in five minutes, land connected, and call via WhatsApp from the taxi to the hotel. Have a good trip.
