If you're planning a trip, sooner or later you'll ask yourself the same question I did: how does internet work in Dubai and which option is truly worth it? The Emirates is a hyperconnected country, but it has a peculiarity that catches almost all tourists off guard: internet calls are restricted. Here, I compare all the alternatives, no fluff.
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 that connects to a mobile network goes through one of these two, supervised by the TDRA, the telecommunications authority. This concentration explains two things: 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 in much of Dubai, and several ways to connect. The difference between them is not in speed, but in price and whether you'll be able to 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 major shopping malls. In terms of speed, you won't miss anything.
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 internet voice and video calls. 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 whole 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: relying on your carrier's roaming, surviving on Wi-Fi, buying a local Emirati SIM card, or having a travel eSIM activated from home. Each has its logic and a traveler profile it suits.
| Option | Estimated Price (7 days) | WhatsApp/FaceTime Calls | When it's worth it |
|---|---|---|---|
| Your carrier's roaming | From free (EU with package) to €60-100 or more | Usually yes (traffic routed externally) | If your plan includes the Emirates at no extra charge |
| Wi-Fi only | €0 | Depends on Wi-Fi; often blocked | Short trips and hotel-based, not venturing out much |
| 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 sell you a fantasy: 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—restores your internet calls. Wi-Fi is useful for downloading heavy files at night. If you want a full breakdown of prices versus your carrier, I cover it in the comparison of eSIM vs. roaming.
Hotel, mall, and taxi Wi-Fi
It must be acknowledged: Dubai is probably the city where it's easiest to find free Wi-Fi. The Dubai Mall, the 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 use, it is. But there are three drawbacks 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 before you can even get in.
- 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 uses an Emirati connection, so internet calls are usually blocked there too. This is the most common mistake: people assume they'll be able to video call home from the hotel, and then discover they can't.
Wi-Fi is a good complement, never the main plan. And if you were thinking of renting a portable router, let me save you some 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
There's good news and not-so-good news here. The good news: when you go through immigration 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 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 the arrivals counters with around 1 GB for 24 hours.
The fine print is that these gifts expire in one day and are a hook for you to top up with 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 a biometric scan, and queuing at the counter. If you're traveling as a family, multiply the hassle per person.
And the big drawback, the one no one 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 card perfect for data and still can't make WhatsApp calls. The general analysis is in eSIM vs. local SIM.
Your carrier's roaming: what it really costs
The Emirates is not in the European Union, so the "roaming like at home" rule doesn't 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 bonus for zone 2 or 3 —from €3 to €12 per day— or, if you don't contract it, consumption-based billing, which is where the triple-digit shocks come from. Ten days with an €8 daily bonus 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 home operator and does not exit through the Emirati APN, so WhatsApp calls usually continue to work. This is why an acquaintance might tell you "WhatsApp worked fine for me in Dubai": they were roaming and didn't know it.
The problem is that you pay for this privilege at a premium price, when the same technical behavior can be achieved for a fraction of the cost.
The VoIP call restriction: WhatsApp and FaceTime
Let's get straight to the point, because this is the fact that changes your trip. In the Emirates, internet voice and video calls (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 real-time calls, either voice or video. The call button appears, but the phone rings without connecting, or cuts out 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 require the other person to install them too, 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 exits. The filtering is applied to the local Emirati APN: if your data doesn't go through there, there's nothing to filter. This is the loophole that roaming and travel eSIMs exploit, without breaking any laws.
Why a travel eSIM usually saves your calls
A travel eSIM is not an Emirati operator: it's a roaming profile. It connects to the e& or du antenna for a 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 traffic does not cross the domestic Emirati APN, call filtering is not applied, and WhatsApp or FaceTime calls work as if you were at home. It's the same mechanism as expensive roaming, but at an eSIM price. And you achieve it without removing your usual SIM: you leave your number active for bank SMS and data on the 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 carrier's roaming | Your home carrier | 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 is that the restriction applies to domestic traffic and that roaming connections do not pass through that filter. If you depend on calls, have BOTIM installed as a backup plan. And if you're not clear on 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 any 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 upstairs. 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, everyone's peak time for 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 is 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 indeed areas without coverage. Download offline maps before you go.
A practical tip: in the desert, the biggest enemy is not lack of network, but battery life. Extreme heat drains it, and a phone searching for signal consumes twice as much. Always carry an external battery.
How much data you need for the 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 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 scroll) | 250-500 MB |
| Upload 20 photos to cloud | 80-150 MB |
| Netflix or YouTube (1 hour HD) | 1-3 GB |
With these numbers, my rule is simple: count between 500 MB and 1 GB per day for normal tourist use (maps, messaging, social media, an occasional video call). A 7-day trip is well covered with 5 GB; if you're constantly uploading stories, go up to 10 GB.
And what you should absolutely not do is stream series with mobile data: save that for the hotel Wi-Fi, which in the Emirates is usually very fast. If you want a specific plan recommendation by number of days, you can find it detailed in my specific guide to 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 a visa on arrival for Spaniards, and the metro connects the airport to Downtown in half an hour—and there you do 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 calling 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 uses 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 restricted at the network level by TDRA regulations. With roaming data (a travel eSIM or your carrier'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 permitted 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 local 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 calling 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 use a local network, they don't allow internet calls.
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 a few video calls, counting between 500 MB and 1 GB daily. If you constantly record and upload videos, consider 10 GB. Leave streaming for the hotel Wi-Fi.
Is there coverage in the desert and at the Burj Khalifa?
Yes, in both. At the Burj Khalifa observation deck, 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. In 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 mobile 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 in 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 before you leave home with a roaming connection, use the hotel Wi-Fi for heavy usage, and forget about queues and surprise bills. It's cheaper than roaming, faster than a local SIM, and, furthermore, it gives you back the calls that Emirati networks take away.
If you want to get it ready before flying, here is my eSIM for the United Arab Emirates: activate it in five minutes, land connected, and call via WhatsApp from the taxi to the hotel. Have a good trip.
