How much does data roaming cost?
The cost of data roaming is not a fixed number: it depends on your operator, the country you are visiting, and whether you activated a package or opted for per-megabyte billing. With Tigo, as with most operators in Latin America, the price changes according to the destination and plan, so it's best to check before you travel, not after.
That's the inconvenient part of these types of searches: any concrete figure you are given today may be outdated tomorrow. Operators frequently adjust their roaming packages, and the price also usually varies by zone (activating data in the United States is not the same as in Europe or another Latin American country). If you want an overview of how that cost is structured among operators, you can also check this guide on how much roaming costs. Here, instead of repeating a number that has probably already changed, we give you the criteria that remain stable to decide whether your operator's roaming is convenient for you or if an alternative such as an international data eSIM is better.
The only thing you can be sure of without needing a source: traditional roaming almost always costs more per gigabyte than a local data plan or an eSIM purchased specifically for the destination, because your country's operator is reselling access to a third party's network abroad. That extra margin is what then translates into the bill that surprises you.
Are you automatically charged when you activate roaming?
With most operators, activating data roaming on your cell phone does not trigger a charge by itself: the charge comes when you actually consume data with roaming turned on. The problem is that this consumption can start without you realizing it, because background applications (email, social networks, updates) continue to function even if you are not actively using the phone.
This is where it is convenient to distinguish between two very different scenarios:
If you purchased a roaming package with a defined data limit, the risk is running out of connection in the middle of the afternoon. If you left roaming in "pay-as-you-go" mode without any package activated, the risk is an unlimited bill. These are two opposite problems, and it is important to know which one you have before getting on the plane.
There is a detail that almost no one checks and that can leave you paying for something you never used: the "data roaming" switch on the cell phone itself must be activated in addition to any package you have contracted with the operator. It is common to buy a roaming package and then discover, once at your destination, that the phone had it deactivated by factory settings or because you turned it off yourself when returning from your last trip. Checking that setting takes ten seconds and avoids both the scare of "no signal" and that of paying for a package you never got to use.
How to activate Tigo roaming outside of Colombia?
If you have a Tigo line (in Colombia or another country where it operates) and you are going to travel, the general process involves a few basic steps: checking the official application or the operator's website to see if your plan includes international roaming, confirming if the destination has a specific package, activating it (if applicable) before leaving, and confirming on your cell phone that data roaming is turned on upon arrival.
We are not going to give you a USSD code or an exact menu path, because it changes between app versions and countries, and an outdated instruction can leave you without data at the airport. What you can safely do:
| Step | What to do | Why it matters |
|---|---|---|
| 1 | Check in the app or official website if your line has roaming enabled | Not all plans include it by default |
| 2 | Confirm if the destination has a specific package or pay-per-use billing | The price and data cap change depending on the country |
| 3 | Activate the package before leaving, not once at the destination | Some take time to activate or require prior local signal |
| 4 | Turn on data roaming on your cell phone upon arrival | Without this setting, the contracted package will not be used |
If your trip includes more than one country, this process is repeated for each destination unless the package explicitly covers it. It is precisely on multi-country trips where more people end up paying too much, because they assume that roaming "is already activated" when they cross the border.
What to check before contracting roaming (checklist)
Before deciding whether to stick with your operator's roaming or look for an alternative, there are six objective questions you can answer yourself by checking the app or official website, without relying on what a comparator with vested interests tells you:
- Coverage: Is the country or countries of your trip included, or only some large markets?
- Data cap: Does the package have a clear limit in gigabytes or is it "unlimited" with reduced speed after exceeding certain consumption?
- Validity: Does the package last for the duration of your trip or does it expire earlier, forcing you to buy another one halfway through your stay?
- Real speed: Do you browse in 4G/5G or does roaming leave you on a slower network once the high-speed segment is exhausted?
- Hotspot: Can you share that data with a laptop or with another person in the group, or does the package block it?
- What happens if it runs out: Does the service cut off, continue charging per additional megabyte, or simply lose speed?
None of these answers depend on the operator's brand: these are fine print questions that apply equally to Tigo as to any other provider, including an international data eSIM. The difference is how easy it is to find those answers before traveling.
Traditional roaming vs. data eSIM: a comparison
With these six criteria now defined, the comparison between sticking with your Tigo line's roaming and buying a data eSIM for your trip becomes more concrete. There is no universal winner here: it depends on your case.
| Criterion | Local operator roaming (Tigo or other) | International data eSIM |
|---|---|---|
| Coverage | Depends on the operator's agreements with each country, varies by destination | More than 200 destinations with the same type of product |
| Keeps your local number | Yes, same number for calls and SMS | Data only; voice number remains with your physical SIM |
| Cost control | Varies by operator and contracted plan | Data package with fixed cap, defined before travel |
| Activation | Requires managing it with the operator before or during the trip | Activation in approximately 1 minute, from the app |
| Need to change physical SIM | No | No: it is installed as an additional digital profile |
| Support during the trip | Depends on the operator and the channel available in that country | 24/7 by email and WhatsApp, in all languages |
The row that weighs most for most travelers is cost control: with an eSIM you know beforehand how much you will pay and for how many gigabytes, while with traditional roaming that certainty depends entirely on the fine print of the plan you have contracted with your operator.
Real coverage: does it work in all countries?
Neither the roaming of a local operator nor any eSIM on the market literally covers "every country on the planet." What changes is the breadth of the network of agreements behind each option. The roaming of an operator like Tigo depends on the agreements that company has signed with carriers in each country; some destinations will be well covered and others will not, and that list can change without prior notice.
An international data eSIM, on the other hand, is specifically designed for travelers and is usually built on networks in several countries at once. In the case of PuraSIM, coverage reaches more than 200 destinations, which reduces the risk of arriving in a country and discovering that your original operator does not have an agreement there.
This is especially relevant if your trip includes several countries on the same route (for example, a tour of different cities in different destinations): checking destination by destination if your local operator has coverage there can take more time than simply activating a product designed for multi-country travel from the start.
Activation: how long does it take to get data?
The time it takes to get data working is also an objectively comparable criterion. Activating roaming with your local operator usually involves coordinating the package before the trip (or managing it from the app at the destination, if there is a signal to do so), and the activation time can vary depending on the operator and the country.
An eSIM purchased in advance activates in approximately 1 minute from the application, and you can do so as soon as you land and connect to the airport's Wi-Fi, without depending on a specific operator's signal being available at that time. In addition, by purchasing it in advance, you have up to 180 days from the purchase to activate it, which gives you leeway if your itinerary changes or if you prefer to have it ready and activate it just upon arrival.
This 180-day window is especially useful for those who buy plane tickets well in advance and prefer to resolve their trip's connectivity without leaving it until the last minute, but also don't want the package to "expire" by buying it too soon.
Support if something goes wrong during your trip
When something goes wrong halfway through your trip — you can't connect, the package ran out sooner than expected, you don't know how to check the remaining consumption — the available support channel at that moment is as important as the price you paid. Here it is important to be honest: there is no universal telephone support for these types of services, neither in traditional roaming nor in most eSIMs on the market; the usual channel is digital.
In the case of PuraSIM, support is available 24/7 in all languages by email and WhatsApp, which in practice means you can write from your cell phone without relying on coverage to make a call. Before contracting any connectivity product for travel, it is worth confirming what support channel it offers and if it is available outside of business hours in the country of origin, because connection problems do not give advance notice or respect time zones. If you are concerned about how often these things go wrong, here we review the most common problems with an eSIM and how to solve them without wasting travel time.
Depending on the type of traveler: what is best?
There is no single answer to "roaming or eSIM": it depends on the travel profile. This table summarizes the most common cases:
| Traveler profile | What they need | What they should check first |
|---|---|---|
| Short trip to a single country | Enough data for basic navigation and maps | If their operator's roaming covers that specific destination |
| Long or multi-country trip | Broad coverage without renegotiating a plan at each border | An eSIM with coverage in all destinations on the route |
| Business trip | Maintain local number for calls and stable data | Combine physical SIM (voice) with data eSIM, without losing the number |
| Trip on a tight budget | Exact control of how much will be spent on connectivity | A data package with a fixed cap defined before leaving |
The case of the business trip deserves a clarification: you don't have to choose between your Tigo line and an eSIM. You can keep the physical SIM for calls and SMS with your usual number, and install an additional eSIM only for data, since most recent cell phones support both at the same time. If you are not clear on how they differ in practice, this comparison between eSIM and physical SIM explains it in more detail.
When it IS convenient to stick with Tigo (and when it is not)
For this article to be useful and not just a biased comparison, it must be said clearly: there are situations where sticking with your operator's roaming makes more sense than buying something additional.
It is convenient to stick with your operator's roaming if:
- You need to maintain calls and SMS with your usual number as a priority, not just data.
- Your plan already includes roaming at no additional cost in the exact destination you are traveling to.
- The trip is to a single country where you have confirmed that your operator's coverage is good.
- You prefer to handle everything from the same account you already use and bill monthly, without managing a new product.
However, it is not convenient to add an eSIM if your trip is so short that the savings do not compensate for the time to configure it, or if your cell phone is not compatible with eSIM (you can confirm your model in this list of eSIM compatible cell phones before buying any product of this type, whether from PuraSIM or another provider). And it is not convenient, under any operator or provider, to activate any data package for travel without first reviewing the consumption limit and what happens when it runs out: that fine print is what determines whether you end up paying what you expected or much more.
Frequently asked questions
How much does data roaming cost with Tigo?
There is no single figure: it varies depending on the destination country, the contracted plan, and whether you activated a specific package or opted for pay-per-use. The reliable way to find out is to check the Tigo app or official website just before traveling, as prices are updated frequently.
Does Tigo automatically charge when you activate roaming?
The charge depends on consumption, not just on having roaming turned on. If you haven't activated any package and left roaming in pay-per-use mode, any data consumed by background applications can incur charges without you immediately noticing.
How to activate Tigo roaming outside of Colombia?
In general: check the app or official website if your line has roaming enabled, confirm if there is a specific package for your destination, activate it before leaving, and upon arrival, verify that data roaming is turned on on your cell phone.
What happens if I run out of data in my roaming package?
It depends on the plan: some cut off the service until you buy another package, others reduce browsing speed, and others charge per additional megabyte. This is one of the questions worth resolving before traveling, not when you've already lost connection.
Can I use an eSIM and keep my Tigo number active?
Yes. Most recent cell phones allow you to have the physical Tigo SIM active for calls and SMS, and at the same time an eSIM installed only for data. You don't have to choose one over the other.
Does the eSIM work on the same cell phone where I have my Tigo SIM?
Yes, as long as the phone is compatible with eSIM technology (most mid-range and high-end models from recent years are). Both profiles coexist on the same phone without the need to change devices.
What do I do if my phone is not eSIM compatible?
In that case, your carrier's roaming or a local physical SIM are still the available options. Before buying any eSIM, it is advisable to confirm the compatibility of your specific phone model.
How long before the trip should I buy the eSIM?
You can buy it well in advance without losing the benefit: you have up to 180 days from the purchase to activate it, so you can sort it out as soon as you buy the ticket and activate it the day you land.
Conclusion and recommendation
If your Tigo line's roaming already covers the country you're going to well, and you need to keep your number for calls, there's no reason to complicate things: check the package, confirm the data cap and what happens when it runs out, and travel with peace of mind. That scenario exists and is legitimate.
But if your trip includes several countries, if you value knowing exactly how much you're going to pay for data beforehand, or if you prefer not to depend on your operator having good coverage in each destination on your route, an international data eSIM solves precisely those three things: coverage in more than 200 destinations, activation in approximately 1 minute, and 24/7 support by email and WhatsApp if something goes wrong along the way. Before deciding, it's also worth understanding the general differences between eSIM and roaming and, if you've never used one, reviewing exactly what an eSIM is and how to install it before your next flight.
You can review the available plans by destination in the PuraSIM international eSIM collection and compare coverage and data capacity according to your specific itinerary.
