You leave your country with your cell phone in hand, you land, and that message pops up: "welcome, roaming charges apply". In Latin America, leaving your carrier's roaming on while traveling can cost you more in data than a good part of the trip. In this guide, I'll explain, carrier by carrier (Telcel, Claro, Tigo, Entel, and WOM), how much it costs to use the internet abroad, how much data you actually need, and why a travel eSIM usually costs a fraction of roaming.
How much does roaming cost in Latin America?
It depends on whether you contract a package or browse "per usage." With a roaming package, you pay a fixed fee (per day or per volume); without a package, each megabyte is charged at an emergency rate, and that's when the terrifying bills arrive.
In summary: a daily roaming package in the region usually costs the equivalent of several dollars per day, and volume packages, a bit more but with more data. Browsing without a package can escalate to hundreds in your local currency in a few hours. A travel eSIM, on the other hand, usually costs a few dollars for several GB for the entire trip.
That difference is the key to everything. Roaming is designed for you to stay connected "just in case," not for watching videos or sharing photos for two weeks. Therefore, for a normal trip with normal data usage, the question is not "do I activate roaming?" but "what is the cheapest way to have internet at my destination?". In most cases, the answer is an eSIM for the country you are visiting. I'll break it down carrier by carrier below, and in detail in how much international roaming costs.
Roaming by carrier: Telcel, Claro, Tigo, Entel, and WOM
Each carrier handles roaming in its own way and covers a different region. This table summarizes how each one charges and what is included as a base. Exact amounts change due to promotions, but the structure remains.
| Carrier | Countries of origin | How roaming is charged | Included by default |
|---|---|---|---|
| Telcel | Mexico | "International Sin Fronteras" packages per day or volume; per usage if not contracted | Roaming in the US and Canada in many postpaid plans |
| Claro | Colombia, Peru, Argentina, Central America | Roaming packages by country and by day, with included data | Requires activation + separate package |
| Tigo | Colombia, Bolivia, Paraguay, Central America | Roaming packages by zone/destination region | Prior activation; package per trip | Entel | Chile, Peru | Roaming data packages per day with included data | Separate package depending on destination |
| WOM | Chile, Colombia | Roaming packages or pay-per-use consumption | Prior activation recommended |
As you can see, there's a pattern: almost all require activating and paying for a package before traveling, except for Telcel with the United States and Canada. Each carrier has its dedicated guide with approximate prices and steps: Telcel roaming, Claro roaming, Tigo roaming, Entel roaming, AT&T Mexico roaming and WOM roaming.

If you're traveling specifically to the United States, one of the most common destinations in the region, check the eSIM guide for traveling to the USA.
Why roaming is expensive (and when it is worth it)
Roaming exists because your carrier doesn't have its own network outside its country: it rents the network from a local carrier and passes that cost on to you with a margin. That's why the price per data for roaming is several times what you pay at home. It's not an isolated rip-off; it's the business model: you're paying an intermediary.
When is it still worth it? In three clear cases. One: very short trips, one or two nights, where it doesn't make sense to manage anything else. Two: destinations included "for free" in your plan, such as the US and Canada from Mexico with Telcel's Sin Frontera coverage. Three: when you need to keep your main number active to receive calls and SMS from the bank (although Dual SIM also solves this, as you'll see). Outside of these cases, for a multi-day trip with maps, messaging, social media, and some video, an eSIM is almost always better. If you want a step-by-step guide to avoid overspending, I wrote a guide on how to avoid roaming.
How much data do you really need?
Before deciding between roaming and eSIM, it's worth knowing how much data a trip consumes. People tend to overestimate: WhatsApp text hardly uses any data, and what consumes data is video, video calls, and uploading photos and stories. These are real references for you to calculate without fear:
- 1 GB is enough for several days of maps, messaging, and light browsing, or about 1 to 2 hours of video in standard definition.
- A one-week trip with normal usage (daily maps, WhatsApp, social media, some video) usually uses between 3 and 5 GB.
- Two weeks or if you share internet with another device (hotspot): calculate 7 to 10 GB or a plan with top-up.
With those numbers in mind, comparing is easy: a 5 or 10 GB eSIM data package for your destination usually costs considerably less than the same volume on roaming. And if you run short, you can always top up. To accurately dimension your case, check out the eSIM guide for Latin America depending on where you travel.
The alternative: a travel eSIM
An eSIM (embedded SIM) is a digital chip that is already inside your phone. Instead of activating your carrier's expensive roaming, you buy a data plan for the country you're going to visit, receive a QR code, scan it, and arrive with internet. You don't change physical cards or lose your local SIM.
What's important for a Latin American traveler is Dual SIM: your phone uses two lines at once. Your Telcel, Claro, or whatever SIM you use stays in to receive SMS and calls from the bank; the eSIM handles the travel data. You keep your WhatsApp with the same number and pay a rate designed for tourists, not for emergencies. In eSIM vs. roaming, I compare both in depth, and in what data roaming is, I explain the technical term behind "roaming."
Roaming vs. eSIM: how much you save
There's no single answer; it depends on how many days you travel, where, and how much data you use. This quick comparison helps you decide without complicated calculations.
| Situation | Your carrier's roaming | Travel eSIM |
|---|---|---|
| 1-2 night trip | Convenient if your plan includes it | Only worth it if you use a lot of data |
| 1-3 week trip | Expensive unless destination is included | Usually the most economical option |
| USA/Canada from Mexico | Often included (Sin Frontera) | Alternative if your plan doesn't cover it |
| Europe, Asia, medium data usage | Requires international package | Recommended |
| Approximate cost for several GB | Daily fee or volume with margin | A few dollars for the trip |
| Your main number | Kept | Also: Dual SIM keeps it |

How to get everything ready before flying
The great advantage of the eSIM is that you prepare it from home, with your Wi-Fi and without rushing at the airport. These are the steps:
- Confirm that your phone is eSIM compatible (most iPhones since the XS in 2018 and recent mid-to-high-end Androids are).
- Choose the plan for the country or region you are visiting based on the days and GB you calculated above.
- Purchase and receive your QR code by email in minutes.
- Scan it from your phone settings and leave the eSIM installed, but don't activate it yet.
- Upon landing, activate the eSIM data and deactivate data roaming for your local SIM.
That last point is key: turn off data roaming for your main line when you arrive, so you only browse with the eSIM and your local SIM doesn't generate any extra cost. I'm leaving you the guide on how to activate and manage data roaming so you can confidently control both lines.
Common mistakes that inflate your roaming bill
Most roaming scares don't come from bad luck, but from three or four oversights that are repeated trip after trip. Avoid them and you'll have half the problem solved:
- Landing with data roaming on without having contracted anything: the phone connects and starts syncing in the background at a high rate.
- Leaving apps updating in the background (photos to the cloud, email, updates): they consume data without you noticing.
- Watching video or making video calls on pay-per-use roaming: this is what drains your balance fastest.
- Sharing internet via hotspot without realizing it's running on roaming.
- Assuming your plan "covers the whole world": almost always, it only covers one zone (e.g., North America).
- Leaving the purchase for the destination airport: inexpensive solutions are arranged from home, calmly and with Wi-Fi.
With an eSIM ready beforehand, none of these mistakes cost you dearly: you arrive, activate the eSIM, and turn off roaming for your local SIM, and that's it.
Frequently Asked Questions
What is the cheapest way to get internet when traveling from Latin America?
For trips longer than two or three days, a travel eSIM is usually the cheapest option: you pay a few dollars for several GB in the country you visit, without the roaming margin. Your carrier's roaming only competes when your plan already includes that destination at no extra cost, such as the US and Canada from Mexico.
How much does it cost to leave roaming on without contracting anything?
Much more than you think. Without a package, pay-per-use consumption is charged at an emergency rate and can accumulate hundreds in your local currency in a few hours, because your phone synchronizes email, photos, and apps in the background. If you haven't contracted a package, keep data roaming off.
Do I lose my number if I use an eSIM abroad?
No. Phones with Dual SIM keep your local line (Telcel, Claro, etc.) active for SMS and calls while the eSIM handles the data. You keep your number and your WhatsApp; you just change how you browse.
How many GB do I need for a one-week trip?
For a week with normal usage—daily maps, WhatsApp, social media, and some video—estimate between 3 and 5 GB. If you share internet via hotspot or watch a lot of video, it goes up to 7-10 GB. Almost all eSIMs allow you to top up if you run short.
Does my carrier's roaming include the United States?
It depends on the plan. In Mexico, many postpaid plans with Sin Frontera coverage include the US and Canada. In the rest of the region, traveling to the United States almost always requires contracting a separate roaming package, so it's advisable to check your plan before you leave.
Can I share the eSIM with my family?
Yes, most plans allow you to activate the hotspot to share data with another phone, tablet, or laptop. This is useful if several people are traveling and not everyone wants to buy a plan; just remember that sharing consumes more data, so choose a plan with enough GB.
Conclusion
Your carrier's roaming has its place—very short trips or already included destinations—but for most trips from Latin America, you overpay for an intermediary. A travel eSIM gives you data at tourist prices, keeps your number with Dual SIM, and you can set it up from home. Before your next flight, compare what your carrier charges and decide with numbers. The difference between an eSIM and pay-per-use roaming can be the difference between spending a few dollars or getting a three-figure bill for the same number of travel days, so it's worth taking five minutes before you leave. With the eSIM installed and your SIM's roaming turned off, you travel with the peace of mind of knowing exactly what you're going to pay. Start with your destination in the international eSIM collection and travel connected without bill surprises.
