If you're planning to travel outside of Colombia and are wondering how Claro's international roaming works, or if there's another way to get mobile data without relying on your usual operator, this guide explains both options in simple terms, including a real-life travel example.
What is Claro Colombia international roaming and how does it work?
International roaming is the service that allows your cell phone to continue working outside of Colombia by connecting to a foreign network with which your operator has a commercial agreement. With Claro, when you arrive in another country, your number and cell phone search for an associated network and connect you, without the need to buy a new SIM card at the airport.
Technically, what happens is easy to understand. Your home operator (in this case Claro Colombia) does not have its own antennas in the country you are traveling to, so it "lends" your line to a local operator through a roaming agreement. That local operator provides you with coverage and then bills Claro for the consumption, which Claro in turn charges you according to the plan or package you have contracted. This is why roaming almost always involves an additional cost to your normal plan: you are using a third party's infrastructure.
What is important for a first-time traveler to know is that roaming is not always activated by default. In many cases, it must be requested in advance, a specific package must be contracted, or it must be manually activated from the app or the cell phone's settings menu, because otherwise the operator may block data consumption abroad to avoid surprise charges.
How much does Claro Colombia international roaming cost?
The cost depends on your plan, the destination country, and the roaming package you choose when traveling, so there is no single figure valid for all cases. What remains constant is the logic: you almost always pay an extra on top of your local plan, either per day, per data package, or per metered consumption.
Since prices and conditions change frequently and vary by destination, the most reliable way is to check them directly in the Claro app or on the official website just before traveling, instead of relying on a figure you saw months ago. One piece of information that is worth keeping in mind: if you do not activate any package and simply leave mobile data on when you arrive in another country, consumption is usually billed per megabyte, which is the most expensive way to use roaming and the one that generates most of the surprise bills that circulate as anecdotes among travelers.
Therefore, if you decide to use your operator's roaming, the practical recommendation is to activate a fixed data package before leaving the country, instead of leaving consumption open "just in case."
Which Claro plan includes international roaming?
Operators like Claro usually offer international roaming as a feature that can be added to different postpaid plans, and in some cases also to certain prepaid plans, through additional packages that are purchased separately. It is not always automatically included in all plans: with many operators in the region, it is a service that must be explicitly activated or contracted before traveling.
As plan offerings change over time and depend on the type of line you have (personal, business, prepaid, or postpaid), the safest way to confirm whether your specific plan includes roaming, and under what conditions, is to consult Claro directly through its app, customer service line, or website before your trip. Avoid relying on what an acquaintance told you about their own plan, because the conditions for each line can be different.
An alternative that does not depend on what plan you have contracted with your operator is to use an independent travel eSIM, which works the same regardless of whether your original line is prepaid or postpaid. We will come back to this later.
How to activate international roaming from Claro
The general process for activating roaming with any Latin American operator, including Claro, usually follows a similar pattern, although the exact steps and menu names may vary:
- Check if your line has roaming available. This is confirmed in the operator's app or by calling customer service before traveling, never upon arrival at the destination airport.
- Choose or activate the roaming package corresponding to the country or region you are going to, if your operator requires it.
- Check the mobile data roaming setting within your phone's configuration (on iPhone it is usually in Settings > Mobile Data > Roaming Data; on Android it varies depending on the manufacturer).
- Confirm activation by text message or within the app, and test the connection as soon as you land, before leaving the airport, in case you need to make any adjustments.
One point that many travelers overlook: activating roaming in the app does not always mean that the phone will automatically use data. The "roaming data" switch in the phone's settings is a separate step, and if it remains off, you will still have no connection even if the package is active on the operator's side.
Roaming, in its simplest definition, is when your cell phone connects to the network of an operator other than your own through a commercial agreement between companies. It is not magic or automatic in all cases: it is a contract between two companies that you end up paying for.
Which countries have free roaming?
There is no fixed or universal list of "countries with free roaming," because it depends on the operator, the contracted plan, and the commercial agreements in force at the time of your trip, which change quite frequently. Some operators in the region have special agreements with neighboring countries that reduce or eliminate the additional cost of roaming within a limited area, but these agreements almost never cover destinations outside that specific zone.
If your trip includes countries outside of these specific agreements, it is normal for roaming to have an additional cost, and that cost varies by destination. The correct way to find out if your travel route is covered by any reduced or free roaming agreement is to check it in your operator's app or website before leaving, filtering by the exact country you are going to, because a generic internet answer may be outdated from one month to the next.
This is precisely one of the reasons why many travelers opt for an independent travel eSIM: instead of depending on what agreements your operator has with each country, an international eSIM gives you coverage in more than 200 destinations with the same conditions, regardless of whether or not there is a special agreement between telephone companies.
What is an eSIM and how does it differ from traditional roaming?
An eSIM is a digital SIM card integrated into the cell phone, which is activated by scanning a QR code instead of inserting a physical card. Most cell phones manufactured from 2018 onwards include it, although it is advisable to check the specific model before purchasing one.
The fundamental difference from traditional roaming is who gives you coverage and under what conditions. With Claro roaming, you remain a Claro customer and they "rent" coverage from a foreign operator for you. With a travel eSIM, you directly contract a data plan designed for tourists, which works on the local network of the destination country without going through your home operator. This usually translates into a more predictable experience: you buy a data package with a price and validity defined in advance, instead of relying on roaming rates that can vary by destination.
Both technologies can coexist on the same cell phone without problem. Since the eSIM is independent of your physical SIM, you can keep your Claro line active (to receive calls, SMS, or bank verification codes) while using data from a travel eSIM to browse, use maps, or WhatsApp. This is the "dual SIM" function that most modern cell phones have, and it is what allows you to separate "my usual number" from "my data while traveling."
| Aspect | Operator Roaming (Claro) | Travel eSIM |
|---|---|---|
| Who you buy the service from | From your own operator, as an extension of your plan | From a travel eSIM provider, independently |
| Activation | Requires a package or prior authorization, plus mobile data roaming adjustment on the phone | Scan a QR code; with PuraSIM, activation takes about 1 minute |
| Your usual number | Remains, it's the same line | Remains separate, in dual SIM mode, for calls and SMS |
| Coverage by destination | Depends on your operator's roaming agreements with each country | Consistent coverage in over 200 destinations |
| Cost predictability | May vary by destination and consumption if there is no fixed package | Data package with volume and validity defined at the time of purchase |
Real example: A trip from Bogotá to Mexico City
Imagine you live in Bogotá and are traveling to Mexico City for five days for work. You need to use maps to get around, WhatsApp to coordinate with your team, and at some point, receive an SMS verification code from your bank in Colombia.
With traditional roaming, before leaving, you would check in the Claro app if your plan includes roaming for Mexico, activate the corresponding package if necessary, and verify that the data roaming switch is on your phone when you land. During the trip, all your data consumption goes through that package contracted with Claro.
With a travel eSIM, the process changes order: you buy the eSIM before leaving Colombia (you can do it from home, even on the same day of the flight), install it by following a QR code while you still have Wi-Fi, and leave it ready but deactivated. When you land in Mexico City, you activate the eSIM for data and leave your physical Claro SIM active only for calls and SMS. This way, your maps and WhatsApp work with the local eSIM, while the bank code still reaches you through your usual Colombian number, without having to pay roaming for that specific SMS.
If that same trip continued to another country after Mexico, the difference would be even more noticeable: with roaming, you would have to check again if your operator has an agreement with the next destination, while with an eSIM that covers several countries (or by buying a new one for the next destination) you maintain the same type of process, without depending on what agreements Claro has country by country.
When is roaming convenient and when is a travel eSIM better?
There is no universal answer: it depends on your type of trip, how much you use your cell phone outside of Colombia, and how predictable you want the expense to be.
| Type of trip | Operator Roaming | Travel eSIM |
|---|---|---|
| Short trip (2-3 days) to a single country, occasional data use | May suffice if your plan already includes the destination | Good option if you want a fixed and predictable cost from the start |
| Long trip (2 weeks or more) | Cost can increase if you need several packages in a row | Usually more practical: you choose a data volume appropriate for the duration at once |
| Trip covering several countries | Depends on whether your operator has an agreement with each country on the route | Consistent coverage in over 200 destinations, without checking agreement by agreement |
| Business trip requiring calls to your usual number | Automatically maintains calls, SMS, and data on the same line | Maintains calls and SMS on your line (dual SIM mode) while data goes through the eSIM |
| Need connection as soon as you land, without formalities at the destination | Works if you have already activated the package before leaving | Installed before traveling and activated upon arrival; no need to find Wi-Fi or a store at the airport |
If your priority is simplicity and you don't mind occasionally checking Claro's roaming settings, that may still be your option. If what you are looking for is a defined cost in advance and consistent coverage regardless of the country, a travel eSIM usually solves it with fewer steps.
How to activate an eSIM before your next trip
If you decide to try a travel eSIM, the process is shorter than it seems:
- Confirm that your phone is eSIM compatible. Most mid-range and high-end phones from 2018 onwards are, but it's a good idea to check the specific model before buying one.
- Choose the destination and data volume according to how much you plan to use maps, social media, and messaging.
- Buy the eSIM in advance. At PuraSIM, you have up to 180 days from purchase to activate it, so you can buy it weeks in advance without it "expiring."
- Install it while you have Wi-Fi, either at home or at the airport, by scanning the QR code you receive by email.
- Activate it upon arrival at your destination, or just before takeoff if you prefer to have everything ready from the air. Activation takes about 1 minute.
If you have any questions during the process, support is available 24/7 in all languages via email and WhatsApp, so you don't depend on office hours to solve a last-minute problem before a flight.

Frequently asked questions
Do I need to change my cell phone number to use a travel eSIM?
No. The travel eSIM occupies a second line within the same cell phone, in dual SIM mode. Your Claro number remains active for calls and messages while the eSIM handles mobile data.
Does WhatsApp work with a travel eSIM?
Yes. WhatsApp uses mobile data or Wi-Fi, it does not depend on which SIM is associated with your account, so it works normally using eSIM data.
What happens if I run out of eSIM data in the middle of my trip?
You can buy an additional package or a new eSIM for the same destination from the app or the provider's website, without having to visit a physical store.
Can I use the eSIM and the physical Claro SIM at the same time?
Yes, as long as your phone supports dual SIM (physical SIM + eSIM), which is the case for most recent models. You can check the list of eSIM compatible phones before purchasing.
Does the eSIM work on any cell phone?
Not all models are compatible yet. It is advisable to check the specific model of your cell phone before buying an eSIM, especially if it is an older device.
How far in advance should I buy the eSIM before traveling?
You can buy it weeks in advance without any problem: you have 180 days from the purchase to activate it, so there is no urgency to leave it until the last day.
Can an eSIM be lost or damaged like a physical SIM?
Not in the same way. Being digital, it cannot be physically lost or damaged, although if you change phones, you usually need to reinstall it in the new device.
What's the difference between roaming and eSIM if I've never used either?
Roaming extends your usual line (e.g., Claro's) to work in another country through an agreement between operators. A travel eSIM is a separate data plan that you install on the same phone, specifically designed for tourists. You can read more in this eSIM vs. roaming comparison.
Conclusion
Claro Colombia's international roaming can work well if your trip is to a single country with which your operator has a good agreement, and if you don't mind checking plans and settings before each departure. But if you're looking for a predefined cost from the start, consistent coverage regardless of the destination, and the ability to keep your Colombian number only for calls and SMS, a travel eSIM solves these three points with less friction.
If this is your first time exploring this option, the simplest path is to start with the basics: review the complete guide to traveling with eSIM, confirm your phone is compatible by following the step-by-step installation guide, and once you've decided on your next destination, check PuraSIM's eSIM for Colombia to see plans and coverage. If you travel frequently within the region, this guide on Claro roaming in Costa Rica might also be useful as additional reference. And if you have any technical questions about phone compatibility or installation, the eSIM vs. physical SIM comparison answers the most common questions before purchasing.
