What is international roaming and how does it work with Claro?
International roaming is the service that allows you to use your cell phone outside your country by connecting to another operator's network, thanks to an agreement between that operator and yours. Claro, operating in several countries in the region, can offer this service with conditions that change depending on your plan, your country of origin, and your destination.
The basic idea is simple: your SIM card remains the same, but instead of "talking" to your country's Claro network, your cell phone connects to another operator's network (it could be the local Claro in the country you are visiting, or a third party with whom there is an agreement). This connection allows you to continue receiving calls, messages, and data, although almost always under different conditions than your usual plan: it may cost extra, be limited to a certain amount of data, or only work if you activated a specific package before traveling.
The important thing for first-time travelers thinking about this is to understand that "roaming" is not a single, identical service everywhere: it is a general label for "your cell phone works in another country," and what it exactly includes depends on each operator, each plan, and often, each destination country.
Which Claro plans include international roaming?
Claro operates as separate national companies in different Latin American countries (Mexico, Colombia, Argentina, Chile, Peru, among others), and each manages its own plans, prices, and roaming conditions. This means there is no single valid answer for everyone: a Claro postpaid plan in one country may include a certain amount of data abroad, while in another country the same type of plan may require contracting an additional package.
In general terms, operators in the region usually handle roaming in one of these ways: daily packages (you pay a fixed price and have limited data, calls, or SMS for 24 hours), data volume packages (you buy a certain amount of MB or GB valid during the trip), or, to a lesser extent, plans that already include some roaming at no additional cost within certain limits. Which of these options applies to your line depends on your current plan and the country where you contracted it.
As these conditions change over time and vary by country, the only reliable way to know exactly what your plan includes is to check directly in the Claro app, on its website, or by contacting their customer service before traveling. If your line is from Claro Costa Rica, for example, there is already a specific guide on international roaming with Claro in Costa Rica that details that specific case.
Which countries have free roaming?
The honest answer is that "free roaming" — that is, using your cell phone in another country exactly as in yours, without any additional charge — is not guaranteed for the general public on most routes within Latin America. In some regions of the world, there are agreements between countries that eliminate extra roaming charges between them, but outside of these specific blocks, it is usual for the operator to apply some type of charge or limit when you leave your country.
The fact that Claro has a brand presence in several countries in the region also does not automatically mean that moving between those countries is free: each national Claro is a different operation, and sharing a name does not mean sharing prices. There may be a specific agreement between countries where Claro operates, but this depends entirely on the contracted plan and must be confirmed on a case-by-case basis.
Therefore, if your trip includes several countries and you want to avoid surprises, it is best not to assume anything about "free roaming" and instead compare the real cost of each available alternative for your specific route, something we will discuss later in this article.
How to activate Claro roaming abroad?
The process varies depending on the country where you contracted your line, but in general, it follows a similar logic:
- Confirm before traveling if your line has roaming enabled. Some prepaid lines have it deactivated by default and it must be activated from the app or by calling customer service.
- Check available packages for your specific destination country in the Claro app or on its website; prices and data coverage change depending on the route.
- Contract the corresponding package before leaving your country, or as soon as you land, following Claro's instructions (from the app, dialing a short code, or through customer service).
- Verify that the package is active before confidently using data; if you have doubts, keep mobile data off until confirmed.
- Keep track of consumption during the trip, usually available in the same app, to avoid a surprise upon return.
None of these steps are exclusive to Claro: it is, in general, how to activate roaming with any traditional operator. The difference between operators lies in the details of price, coverage, and ease of the process, which only the operator itself can confirm with accuracy.
Why can roaming be more expensive than you expected?
Most complaints about roaming do not come from it being expensive by definition, but from it being activated — or remaining active — without the person realizing how much they are consuming. There are several typical reasons:
- The cell phone continues to consume data in the background (updates, backups, notifications) even if you are not actively using any app.
- Daily packages are charged in full even if you only use them for a few minutes, so crossing midnight or changing time zones can add an extra day without you noticing.
- If you exceed the data limit included in a package, some plans automatically charge for each additional MB at a higher price.
- A package designed for a specific country may not cover you if you cross the border to another destination within the same trip.
- Forgetting to deactivate the roaming package when returning home, generating unnecessary charges on days you were no longer traveling.
Roaming is not usually expensive by itself: it becomes expensive when the cell phone continues to consume data without anyone activating or defining any limit.
Understanding this helps make better decisions: the problem is almost never "roaming" as a concept, but the lack of control over what the cell phone consumes while traveling.
What alternatives are there to operator roaming?
When traveling outside your country, you essentially have four ways to get data on your cell phone. None is "the best" in all cases: it depends on your destination, the duration of the trip, and how much you want to control spending beforehand.
| Option | What it is | Main advantage | Main disadvantage | Ideal for |
|---|---|---|---|---|
| Operator roaming (Claro or other) | You use your own line connected to a foreign network through an agreement | Nothing changes on the cell phone | Price and coverage difficult to anticipate without checking beforehand | Short trips where you prioritize simplicity |
| Local physical SIM | You buy a new SIM card upon arrival at the destination | Local rates, sometimes lower | You lose your number while using it; you have to find it and physically change it | Long trips to a single country |
| Travel eSIM | A digital profile that you install via QR code, without changing the physical card | It is installed before traveling and coexists with your usual line | Requires an eSIM-compatible cell phone | Traveling to one or several countries without losing your number |
| Portable WiFi (rented modem) | A separate device that generates a WiFi network with mobile data | Can be shared among several devices or people | One more device to carry and not lose | Groups or families traveling together |
To compare the traditional roaming option with an eSIM in more detail, you can check this guide on eSIM vs. roaming, which goes into that detail with more examples.
What is an eSIM and how does it work in practice?
An eSIM is a digital SIM card: instead of inserting a physical card into your cell phone, you install a profile by scanning a QR code. This profile works exactly like a traditional SIM for mobile data purposes, but it does not occupy the physical tray of the cell phone. If your device supports dual SIM (one physical and one eSIM, or two eSIMs), you can keep your Claro line active for calls and messages while using the eSIM only for data.
This is precisely what makes it a practical alternative to traditional roaming for those who did not know this option existed: you do not have to negotiate roaming packages with your operator or go looking for a physical store when you arrive in another country. You install it calmly before traveling and it is ready to activate when you land. You can see the complete step-by-step in this guide on how to install an eSIM, and a more general introduction in what an eSIM is.
| Criterion | Traditional roaming | Travel eSIM |
|---|---|---|
| Where it is activated | With your operator, before or upon arrival at the destination | It is installed before traveling, activated upon arrival |
| Change physical card | No | No |
| Price known in advance | Must be checked with the operator for each route | Paid upon plan purchase, before traveling |
| Risk of automatic charges for excess | Exists, depending on the plan | No: the plan comes with a defined amount of data |
| Coverage for multiple countries | Depends on the operator's agreement with each country | Depends on the chosen plan; some cover several destinations |
In the case of PuraSIM eSIMs, coverage reaches more than 200 destinations, activation takes approximately 1 minute once the profile is installed, and you have 180 days from purchase to activate it, so you can buy it in advance without rushing for the exact travel date.
Example: a trip from Mexico to Colombia and Peru
Imagine you live in Mexico, have your line with Claro, and are going to travel for 12 days: first to Bogotá and then to Lima. Before leaving, you compare two paths.
The first is to check in the Claro app what roaming package exists for Colombia and what for Peru, as it will probably not be the same package or the same price for both countries. If the trip crosses from one country to another, you must confirm if the package contracted for Colombia continues to work upon arrival in Peru or if you need to contract a new one when crossing.
The second path is to install a travel eSIM before leaving Mexico, while you still have stable WiFi at home, choosing a plan that covers both countries of the itinerary. The eSIM is ready but inactive until you decide to turn it on, so there is no rush to install it exactly on the day of the flight. Upon landing in Bogotá, you activate it and start using data without having to find a store or wait for your operator to confirm the package in time.
A not-so-obvious detail that helps with this type of travel: on a dual SIM phone, you can leave your Claro line's mobile data off throughout the trip — to avoid any roaming charges — but keep that same line on only for SMS and calls. This is useful because several banks and apps continue to send verification codes (2FA) via SMS to your usual number, and that messaging service can continue to function even if the data for that line is off, while the eSIM handles all navigation.
With either path, you can use your cell phone on the trip; the difference is in how much you know in advance about what you are going to pay and how much time it takes to resolve it before boarding the plane.
How to avoid bill surprises upon return
Regardless of whether you choose traditional roaming, local SIM, or eSIM, these practices reduce the risk of an unexpected charge upon return:
- Leave your main line's data roaming deactivated by default and activate it only when you confirm the package and cost.
- Set a data alert or limit on the cell phone itself before traveling, available in the settings of almost any modern device.
- Explicitly ask your operator what happens if you run out of the contracted package: if the service is cut off or if it automatically starts charging per additional MB.
- Write down the exact dates of your trip to be able to review the bill later and detect any charges outside those dates.
- If you prefer not to touch your main line for anything data-related abroad, using a separate eSIM simplifies the review: travel data is completely separate from your usual bill.
Frequently asked questions
Do I need to remove my Claro SIM to use a travel eSIM?
No. Most eSIM-compatible cell phones allow both to be active at the same time (dual SIM), so your Claro line can continue to function for calls and SMS while you use data via the eSIM.
Does Claro roaming activate automatically when I arrive in another country?
It depends on the plan and the country. Some lines, especially prepaid, have it deactivated by default, so it's advisable to check it in the Claro app or ask directly before traveling.
Can I use the same eSIM in several countries during the trip?
Yes, if you choose a plan that covers the region or specific destinations of your itinerary, you can move between those countries without reconfiguring anything, depending on the area covered by the chosen plan.
What if my cell phone is not eSIM compatible?
You can use a local physical SIM or your operator's traditional roaming. It's worth checking before traveling if your model supports eSIM in this guide on eSIM-compatible cell phones.
How long does it take to activate a travel eSIM?
In the case of PuraSIM eSIMs, activation takes approximately 1 minute once you install the profile and decide to turn it on.
How long after purchase can I activate the eSIM?
With PuraSIM, you have 180 days from purchase to activate it, so you can buy it in advance without needing to know the exact travel date.
What do I do if I have a problem with the eSIM during the trip?
You can first check this guide on common eSIM problems. If that doesn't solve it, PuraSIM offers 24/7 support in all languages via email and WhatsApp.
Does eSIM completely replace Claro roaming?
Not necessarily; they can be used together. Many people keep their Claro line active only for calls and SMS, and use the eSIM exclusively for travel data.
Conclusion
Before you assume how much it will cost you to use your cell phone on your next trip, the first thing is to confirm with Claro what exactly your plan includes for each country on your route: there is no single answer and conditions change depending on where you contracted your line. If you prefer not to depend on this consultation every time you travel, or simply do not want to risk an automatic charge you did not see coming, installing a travel eSIM before leaving gives you a known price in advance, coverage in more than 200 destinations and 180 days from purchase to activate it when you need it.
