Does Montenegro have roaming?
Yes, Montenegro has cell phone coverage and your phone connects to a local network as soon as you arrive. The problem is the price. Montenegro is not part of the European Union, so the "included" roaming that your plan might have within the EU does not apply there, and it's easy to end up paying too much without realizing it.
This surprises many travelers because Montenegro is next to Croatia, has a coast on the Adriatic, and, at first glance, "looks" like Europe in the sense that most people use that word: euro as currency, similar signage, consolidated tourism. But for roaming purposes, what matters is not geography or currency, but whether the country belongs to the bloc that regulates those agreements. And that's where Montenegro is excluded.
Why is Montenegro not in the European Union?
Montenegro has been a candidate country for joining the European Union for years, but a candidate is not the same as a member. The accession process involves negotiating different areas chapter by chapter (justice, economy, environment, among others) and can take more than a decade. As long as this process is not closed, Montenegro remains, for practical purposes, a country outside the EU, just like Serbia, Bosnia and Herzegovina, or Albania.
This matters for roaming because the European Union has a rule that obliges operators in its member countries not to charge extra when you move from one country in the bloc to another: this is the basis of what many people call "free roaming in Europe." This rule only applies between countries that belong to the EU (and a couple of countries in the European Economic Area). Montenegro, not being a member, is outside this umbrella, no matter how close it is to Croatia or Italy on the map. If you want to understand the concept of roaming from scratch, you can review what roaming is before continuing.
Which countries are included in the "roaming" everyone talks about?
When someone says "roaming in Europe is free," they almost always implicitly refer to the countries of the European Union plus a handful of countries in the European Economic Area (Iceland, Norway, and Liechtenstein). This is the group within which, if you have a plan from an operator in that bloc, you can use your data, calls, and messages without additional charges, just as if you were in your home country.
The misunderstanding arises when it is assumed that "Europe" as a continent and "the roaming-free zone" are the same thing. They are not. There are European countries, geographically speaking, that are outside that group: Montenegro, Serbia, Bosnia and Herzegovina, North Macedonia, Albania, the United Kingdom (since its departure from the EU), and others. For a traveler departing from Mexico, Colombia, Argentina, Chile, or Peru, this distinction is even less intuitive, because your original plan never had that European roaming to begin with: what you need to check is the international roaming offered by your own Latin American carrier, which is a completely different agreement.
In which countries is roaming free?
It's worth clarifying something here: no roaming is, strictly speaking, free. What exists within the European Union is roaming without additional charges for the user, because regulations oblige operators not to charge extra when you move between member countries. The cost is already absorbed into the price of your monthly plan; it hasn't disappeared.
This scheme applies between EU and European Economic Area countries, provided your original plan is from an operator in that same zone. A Mexican, Colombian, or Argentine plan does not fall under this agreement, even if you travel within the European Union: your original operator still defines its own international roaming conditions, which may include Europe as a bloc, charge per day, charge per megabyte, or simply not offer coverage in some countries. Montenegro, being outside the EU, is almost never included in the "Europe roaming" packages offered by operators, not even European ones.
Which countries does your carrier's international roaming cover?
This depends entirely on your carrier and the plan you have contracted; there is no single answer. The most reliable way to find out is to check the international roaming section in your carrier's app or website and specifically look for "Montenegro" in the list of covered countries, instead of assuming that "Europe" automatically includes the entire continent.
| Plan type | Does it usually cover Montenegro? | What to expect |
|---|---|---|
| Local plan without international roaming | No | The cell phone may lose data signal or only show emergencies upon arrival. |
| Plan with roaming limited to the European Union | Almost never | Montenegro is usually excluded for not being a member country, even if the plan says "Europe." |
| Plan with "global" or "all destination" roaming | Sometimes | Check the list of countries case by case: some global packages do include it, with a charge per day or per MB. |
| Travel eSIM purchased separately | Yes, if the destination exists in the catalog | Coverage designed specifically for the country, without relying on your original carrier. |

What happens if you use your cell phone in Montenegro without notifying your carrier?
If you travel and leave data activated on your cell phone without first checking your plan's conditions, two things can happen. The first is that the cell phone simply won't find a compatible network with roaming agreements, and you'll be left without data, even if you're willing to pay extra. The second, more common and more expensive, is that there is a connection, but under a per-megabyte or per-day charge that your carrier doesn't always clearly display before you activate data.
A simple practice while you decide what to do upon arrival is to leave your cell phone in airplane mode and connect only to Wi-Fi networks (airport, hotel), preventing apps from consuming data in the background without you realizing it. This gives you time to calmly activate your data solution, without the pressure of resolving it as soon as you get off the plane.
A real example: from Mexico City to Kotor Bay
Imagine a typical trip: you depart from Mexico City with a layover in Europe and land at Podgorica or Tivat airport. From there, the most common route is to drive or take a transfer to Kotor Bay, one of the most visited spots in the country, and then continue to Budva or Perast. On that journey, you'll need maps so you don't get lost on the coastal roads, WhatsApp to coordinate accommodation, and data to book a table or order a car without relying on hotel Wi-Fi.
If your Mexican plan doesn't cover Montenegro (which is most likely, according to what we reviewed in the previous section), you basically have three options: pay the daily roaming fee your carrier charges if they offer it, find a physical SIM upon arrival, or sort it out before you leave with a specific eSIM for the destination, which you activate from your phone without having to find a physical store in a country where you don't speak the language.
A common misunderstanding about roaming is assuming it means the same thing in all countries, and only discovering the difference when the bill arrives.
A not-so-obvious detail: if you buy the eSIM before the trip, you don't have to activate it on the same day of purchase. You have up to 180 days from purchase to activate it, so you can buy it as soon as you book your flight and have it ready, without that waiting time reducing the days of use once you activate it in Montenegro.
Alternatives for data in Montenegro
Before deciding, it's worth looking at the options side by side. None is universally "the best": it depends on how long your trip is, whether you'll be moving between several countries, and how comfortable you feel dealing with formalities at your destination.
| Option | What it is | When it's convenient |
|---|---|---|
| Local physical SIM | Chip you buy upon arrival, at a carrier store or kiosk | Long trips where you don't mind looking for a store and changing your phone's physical chip |
| Portable WiFi (pocket wifi) | Device you rent or buy that provides WiFi to several devices at once | Groups or families who want to share a single connection among several devices |
| Travel eSIM | Digital profile installed via QR code, without a physical chip | Travelers who prefer to arrive with data ready from the airport, without relying on finding a store |
If you've never used one and want to understand the differences compared to a traditional chip, the comparison in eSIM vs. physical SIM places them side by side in more detail.
How an eSIM works, explained without jargon
An eSIM is, essentially, the same as a physical SIM (the small card that cell phones use to connect to a network), only instead of being a plastic piece that you insert into a slot, it's a digital profile that is stored directly on the phone's chip. It is installed by scanning a QR code or tapping a link, and in a couple of minutes, the phone is configured with a data plan for that country, without having to open the phone's tray or wait for anything to arrive by mail.
The interesting thing for a trip like Montenegro's is that you can have your local plan's eSIM (Mexican, Colombian, Argentine, whatever it is) and the travel eSIM active at the same time on the same phone, provided the model supports it. This way, you keep your number to receive SMS verification from banks or apps, while using the travel data line for everything else. Before buying, it's a good idea to check if your specific model is compatible: the list is in eSIM-compatible phones, and the step-by-step installation guide in how to install an eSIM. If this is the first time you've heard the term, what an eSIM is explains it from scratch.
Checklist before traveling to Montenegro
With all of the above, here's what you should sort out before getting on the plane, not after:
| Item to check | Why it matters |
|---|---|
| Confirm if your cell phone is eSIM compatible | Not all models support it; it's good to know before buying any digital plan |
| Check your home carrier's international roaming | To know if Montenegro appears in their list of covered countries and at what cost |
| Decide on your data solution in advance | Sorting it out before traveling avoids relying on finding a physical store upon arrival |
| Save offline maps or key routes | As a backup while your data solution is active |
| Save the support contact for your eSIM provider | In case you need help installing or activating the profile at your destination |
If something doesn't go as expected upon arrival, it's good to know beforehand how to solve it: there are specific guides on common eSIM problems and how to fix them without losing travel time.
Frequently asked questions
Does Montenegro have roaming?
Yes, it has cell phone coverage like any country, but as it is not a member of the European Union, the free roaming that exists within the EU does not apply there. What you use will depend on the international roaming conditions of your own operator.
Which countries are included in roaming?
It depends on which roaming you are referring to. The roaming without additional charges from the European Union applies between EU member countries plus Iceland, Norway, and Liechtenstein. Your home operator's international roaming is a different agreement, with its own list of countries, which may or may not include Montenegro.
In which countries is roaming free?
Strictly speaking, none: the cost is already included in the plan price. Within the European Union, there is roaming without additional charges for the user between member countries, but this condition does not apply to Montenegro because it does not belong to the bloc, nor to plans from Latin American operators traveling there.
Which countries does international roaming cover?
It varies depending on the operator and the contracted plan. Some "global" packages do include Montenegro with a charge per day or per megabyte, while packages limited to "Europe" usually exclude it because it is not a European Union country. The only reliable way to find out is to check your own plan's list of countries before traveling.
Do I need a special phone to use an eSIM in Montenegro?
Not a special one, but a compatible one: most mid-range and high-end models from recent years are, but it's good to confirm before buying any digital plan for the trip.
Can I continue to use WhatsApp and maps with an eSIM in Montenegro?
Yes. A travel eSIM gives you an independent data line on the same phone, so apps like WhatsApp, maps, or ride-sharing apps work just like with any other data connection, without the need for Wi-Fi.
What happens if my eSIM runs out of data in the middle of the trip?
It depends on the provider, but generally you can recharge or buy an additional plan from the same phone, without having to look for a physical store or change your profile.
In summary
Montenegro has cell phone coverage like any destination, but it does not have the free roaming of the European Union because it is not a member country of the bloc, even though it is surrounded by countries that are. Before traveling, the important thing is not to guess, but to specifically check what your carrier says about that specific country, and decide in advance if you prefer its international roaming, a physical SIM upon arrival, or a travel eSIM activated before departure.
If you prefer to sort it out without relying on a store upon arrival, you can check the data plan for Montenegro, which is installed from your phone, activates in approximately one minute when you decide, and remains available for up to 180 days after purchase so you can activate it when your trip actually begins. If you need help during the process, 24/7 support is available in all languages via email and WhatsApp, without relying on office hours. And if this trip is just the first of several, the definitive eSIM guide for travel compiles in one place the steps for any destination, among more than 200 available in the catalog.
