¿Qué es el Roaming y Cómo Evitarlo? Guía Completa para Viajeros 2026

Roaming is one of the most feared concepts among travelers — and for good reason. It's responsible for surprise phone bills that can reach hundreds of dollars after just a one-week trip. Understanding what it is, how it works, and most importantly how to avoid it can save you a significant amount of money on every trip you take. DatosdeViaje packages are one of the simplest and most affordable ways to eliminate roaming entirely: you activate your eSIM before leaving, arrive connected, and never see an unexpected charge on your bill.

What exactly is roaming?

Roaming is the service your carrier automatically activates when it detects that your phone is outside its coverage area — that is, in another country. Instead of losing signal, your phone connects to a foreign operator's network that has a commercial agreement with your home carrier, and you can continue making calls, sending texts, and using data.

The problem is the price. Your home carrier has to pay the foreign operator for that access, and transfers that cost to you with an added margin. The result is rates that can range from $3 to $10 USD per MB of data consumed, or $1 to $3 USD per minute of calls, depending on the country and carrier.

The most dangerous aspect of roaming is that it operates silently: if you don't manually disable it, your phone can be consuming data in the background (app updates, emails, notifications) without you realizing it, generating charges even if you haven't actively opened any app.

Why is international roaming so expensive?

Roaming is expensive due to a combination of structural and commercial factors. First, international inter-carrier agreements carry high base costs, especially for destinations outside North America or Europe. Second, carriers add their own margins on top of those base costs. Third, most phone contracts in the region don't include international data in basic packages, so any consumption abroad is billed as a completely separate extra outside the contracted plan.

To illustrate with a concrete example: if your plan includes 20 GB of data per month at home and you use 1 GB in Europe on roaming, those European data don't come out of your 20 GB — they're billed separately, at your carrier's international roaming rate. That 1 GB could cost anywhere from $25 to $150 USD depending on your carrier, destination, and contract type.

Some carriers offer international roaming add-ons as supplements to a plan, but they tend to be expensive relative to what they offer, and coverage can be limited or unstable depending on the country.

How much can roaming cost in different destinations?

Roaming charges vary significantly by destination and carrier. Here are reference estimates to give you a sense of the scale of the problem:

These are charges per day of active use. For a 10-day trip to Europe using normal data roaming, you could be looking at anywhere from $250 to $1,500 USD just for internet. A bill of that size can completely destroy any travel budget.

How does an eSIM work and why does it eliminate roaming?

An eSIM is a digital SIM card built into your phone that can be programmed with any carrier's data, without needing a physical card. When you purchase a DatosdeViaje package for your destination, you install a local data profile directly on your phone using a QR code. When you arrive in the destination country, your phone connects to the local network using that profile — not your home carrier's network.

This eliminates roaming because technically your phone is no longer using your home carrier's network abroad — it's using a local network just like a phone from that country would. No roaming, no unexpected charges, no bill surprises.

And the best part: you can keep your home SIM active at the same time to keep receiving calls and texts on your regular number, using the DatosdeViaje eSIM exclusively for data. To learn more about how this works, check out our guide: How to avoid roaming charges with an eSIM.

What are the ways to avoid roaming while traveling?

There are several strategies to avoid roaming, each with its own advantages and limitations:

A travel eSIM is the option that best combines convenience, price, and connectivity. Nothing to do on arrival, you don't lose your number, and the cost is a fraction of what you'd pay for traditional roaming.

How do I activate a DatosdeViaje eSIM to avoid roaming?

The process is simple and takes under 10 minutes total. First, verify that your phone is eSIM-compatible on our compatible phones page. Second, choose the package for your destination at datosdeviaje.com and complete your purchase. You'll receive a QR code by email immediately.

To install on iPhone: go to Settings > Mobile Data > Add eSIM and scan the QR code. On Android: go to Settings > Connections > SIM and Mobile Data > Add eSIM and follow the instructions. For detailed guides by phone model, visit our installation page.

We recommend installing the eSIM one or two days before your flight. When you land, activate data roaming on the DatosdeViaje eSIM (not on your main SIM) and you'll be connected before leaving the airport. If you have any questions during the process, our team is available via WhatsApp in Spanish and English.

Frequently asked questions about roaming and how to avoid it

What is roaming on a cell phone?

Roaming is the service your carrier activates when you use your phone outside its coverage area — in another country. Your phone connects to a foreign network and your carrier charges you additional fees for every call, text, or MB of data consumed. Those charges can be extremely high and often appear on your bill without warning.

Why is international roaming so expensive?

Roaming is expensive because your carrier pays foreign operators for network access and passes those costs to you with an added margin. In Mexico and Latin America, most phone contracts don't include international data in basic packages, so every MB abroad is billed as a separate extra outside your plan.

How can I avoid roaming on my next trip?

The most efficient way is to activate a travel eSIM before you leave. With a DatosdeViaje package you purchase local data for your destination, your phone connects to the local network without using your home carrier, and no roaming charges are generated.

What's the difference between roaming and a travel eSIM?

Roaming uses your home carrier's network extended abroad at very high rates. A travel eSIM installs a local data profile on your phone and connects you to the destination country's network at local prices, without involving your home carrier at all.

Can I have roaming and an eSIM active at the same time on the same phone?

Yes. Most modern phones support dual SIM. You can keep your home SIM active for calls on your regular number and activate the DatosdeViaje eSIM just for data, eliminating roaming charges without losing your local number.
