How do you activate Movistar roaming?
It's activated in three steps: you confirm your plan includes international roaming, you enable it from your operator's app or portal, and you activate data roaming in your cell phone's settings. If roaming "doesn't work," the problem is almost always in one of these three points, not all three at once.
Movistar operates under this same logic in several Latin American countries —Argentina, Chile, Colombia, and Peru, among others— although the exact name of the option within the menu and the specific steps may vary from one country to another, and even change from one app update to the next. Therefore, before traveling, it's advisable to check the current official app in your country instead of relying on screenshots or instructions from a year ago. If you're looking to understand roaming in general, beyond a specific operator, this guide on how to activate roaming and data roaming covers the part that's the same no matter who you have your line with.
Step 1: Confirm your plan includes international roaming
Before touching any button, resolve the doubt that ruins the most trips: not all plans come with roaming activated by default, and some prepaid plans simply don't include it unless it's contracted as an additional package. Log into your account or app and look for the section of your current plan; if there's no mention of "roaming," "itinerancia" (roaming), or "uso en el extranjero" (use abroad), it's the first sign that you need to contract an add-on before leaving the country.
This is the step most people skip because they assume that, since their cell phone "always has signal" in their country, the same will happen abroad. International roaming is a service separate from the domestic plan, with its own cost and conditions, and the operator may have it deactivated by default precisely to prevent you from activating data abroad without realizing it.
Step 2: Activate it from the Movistar app or portal
With the plan confirmed, the next step is the actual activation. For most operators, including Movistar in the countries where it operates, this is done from the official app or the account's web portal, in a section usually called something like "Roaming," "International Roaming," or "Use Abroad," typically within the data or plan management section.
There you might find two different scenarios: that roaming is already included and you just need to activate the switch, or that you have to contract a specific package with a data allowance and a defined duration. If your plan falls into the second case, check the package's start date: some begin running from the moment you activate them, not from when you arrive at your destination, so it's advisable to calculate carefully when you activate it so you don't lose package days while you're still in your home country.
Step 3: Check data roaming in your phone settings
This is the step that explains most of the "I activated it and it doesn't work" complaints. Activating roaming with the operator only opens the door on the network side; your cell phone has its own independent switch that must also be turned on.
Roaming activated in the operator's app is useless if your phone is still configured not to use data roaming: these are two different switches, one for the network and one for the phone, and both must be set to "on."
On Android, this is usually found in Settings > Network & Internet > Mobile data > Data roaming (or "Roaming data," depending on the manufacturer and system version). On iPhone, in Settings > Mobile Data > Data Roaming. If your phone is a dual-SIM or eSIM model, make sure you are activating roaming on the correct line, as the system may have a duplicated switch and only one of them matters for your trip. Before buying any alternative solution, it's also worth confirming that your model is among the eSIM compatible phones, in case you end up needing a backup option.
Step 4: If you can't use the app, contact Movistar before traveling
When the app doesn't show the roaming option, the account gives an error, or you simply don't have internet access to open it, the remaining option is to contact the operator directly. Most offer some chat, WhatsApp, or social media customer service channel, in addition to physical offices; which ones are available and their hours depend on the country and can change, so confirm it on the official website before showing up or writing.
The important thing about this step is the timing: resolve it before you leave, not at your destination airport. Once you land without data, verifying your identity by phone or waiting for a customer service response becomes much slower without Wi-Fi readily available, and it's common to lose the first hours of your trip—just when you need the map or translator the most—solving something that can be quickly fixed with a stable connection the day before.
How to know if roaming is activated
There are two ways to confirm it, and it's advisable to use both. The first is to check in the app or operator portal that the roaming status or international package appears as "active," with its expiration date visible. The second is the real test: once at your destination, with airplane mode deactivated and mobile data turned on, see if a network icon appears (sometimes a small "R" next to the signal indicator) and if you can load a page without being connected to Wi-Fi.
If the status says "active" in the app but the phone doesn't show data signal upon arrival, the problem is no longer with activation with the operator: it's in the phone's settings (check step 3) or because the local network hasn't yet registered your line, which can take a while and is explained in the next section.
When Movistar roaming activates and how long it takes to reflect
The activation of the service in the account — the operator's "yes" — is usually practically immediate or takes a few minutes. What can take longer is for your cell phone to register on a specific foreign network once you land: the phone has to "introduce itself" to the local network, and that automatic process sometimes takes time, especially if you've just gotten off a long flight and your cell phone was in airplane mode for hours.
That's why it's advisable to activate roaming the day before your trip, not at the airline counter or in the immigration line. That way, when you land, the service is already confirmed on the operator's side, and it's just a matter of the phone finding the local network, which usually happens automatically, without you having to do anything else.
Operator roaming vs. data eSIM: what's best for your trip
Activating roaming with your own operator isn't the only way to have data abroad. The other option, increasingly common, is to install a data eSIM just for the trip, which works in parallel with your main line without affecting your number or your usual plan. If you've never installed one, this guide on what an eSIM is explains the basics before comparing.
| Aspect | Local operator roaming | Data eSIM for travel |
|---|---|---|
| Where it's activated | App or portal of your country's operator | Independent app, not dependent on your local operator |
| Activation time | Minutes, but depends on the local network registering you upon arrival | Activation in approximately 1 minute |
| Activation window | Normally must be activated before or upon arrival | Up to 180 days from purchase to activate when needed |
| Coverage | Limited to countries with your operator's roaming agreement | Coverage in over 200 destinations |
| Cost control | Cost usually reflected on the bill, sometimes days later | Paid before travel, with clear data from the moment of purchase |
| Travel support | Depends on the operator's own channels (vary by country) | 24/7 support in all languages via email and WhatsApp |
If you're traveling to a single country and your plan already includes roaming at no additional cost, activating what you already have contracted might be the simplest option. If you're traveling to several countries on the same itinerary, your plan doesn't include roaming, or you simply want to control your spending before you leave, an independent eSIM is usually more predictable. To install one once you've decided, here's the step-by-step guide on how to install an eSIM, and here you can see the collection of eSIMs for international travel available by destination.
Common errors that cause roaming to "not work"
The vast majority of "I activated roaming and have no data" complaints are explained by a handful of repeated causes. Before assuming something is broken, check this list.
| Common Error | Why it happens | How to avoid it |
|---|---|---|
| You activated roaming in the app, but not on the phone | These are two independent switches: the operator's and the phone's system | Check Settings > Mobile Data > Data Roaming after activating in the app |
| The roaming package has expired | Many packages have a fixed duration that starts from activation, not from use | Note the expiration date upon activation and renew before it runs out |
| The phone did not register on the local network | After a long flight or with airplane mode on, automatic registration can take time | Toggle airplane mode on and off for a few seconds upon landing to force a new network search |
| The plan never included roaming | Some plans, especially prepaid, do not include roaming by default | Verify the plan before traveling, not upon arrival (step 1) |
| The phone's network mode was fixed to an unavailable standard | Some advanced settings force only 4G or only 5G, and that band may not be available on the local network | Leave the network mode on automatic while traveling |
The airplane mode trick in the table above is more useful than it seems: when the cell phone has been in the same place for a while, it tends to get "stuck" on the network search it performed upon landing, even if that search failed. Turning airplane mode off and on doesn't reset roaming or the contracted package, but it does force the phone to repeat the process of searching for and registering on the local network from scratch, which is precisely what often gets stuck after a flight. If after installing an eSIM as an alternative you continue to experience specific failures, this guide on common eSIM problems covers cases not resolved by airplane mode.
Frequently asked questions
Does Movistar roaming have an additional cost?
In most cases, yes, either because the plan charges a specific roaming package or because usage is billed separately. The exact value and conditions change depending on the country and the contracted plan, so confirm it directly in the app or the official portal of your operator before traveling; it's not a fact that can be reliably generalized.
Can I activate roaming the same day of my trip?
Yes, but it's not ideal. Activating it the day before gives you leeway to resolve any app or payment errors before you leave, and prevents you from relying on having a good connection just when you're packing or heading to the airport.
What happens if my phone doesn't have the roaming option and I can't activate it from the app?
Contact the operator through the available channels in your country (chat, WhatsApp, social media, or physical office) before traveling. Resolving it in advance avoids being without data just when you arrive at your destination.
Does roaming work the same as using data in my home country?
Navigation itself is the same, but speed and coverage depend on the agreements your operator has with the local networks in the country you're in, which are not always the same network you would use if you contracted a local line or an eSIM.
How can I tell if I have Movistar roaming without calling the operator?
Check the status of your plan or international roaming package directly in your account's app or web portal; it usually indicates if it's active and until when. Supplement that check with the real test described in this article: mobile data on and airplane mode off once at your destination.
How long does it take for roaming to activate after requesting it?
Account activation is usually a matter of minutes. What can take longer is for the cell phone to register on the destination country's network upon arrival, an automatic process that sometimes takes time, especially after a long flight.
Does an eSIM replace operator roaming?
It can do so for a specific trip: you install an independent data eSIM and use it in parallel with your main line, without depending on whether your operator has a roaming agreement with that country. Your number and your usual plan remain intact for calls and messages.
Do I need to change the physical SIM card to have roaming?
No, operator roaming works with the same SIM or eSIM you already use in your country; it's just a service activation, not a card change. If you instead opt for an independent data eSIM for the trip, that is installed as a separate profile, without removing your main SIM.
Conclusion
Activating Movistar roaming is almost always resolved by checking the same three points: that the plan includes it, that it's turned on on the operator's side, and that it's also turned on on the cell phone's side. If after reviewing the four steps in this article you still don't have data, or you simply prefer not to depend on the coverage and support of an operator that isn't yours, a data eSIM for the trip is the direct alternative: coverage in more than 200 destinations, activation in approximately 1 minute, and up to 180 days from purchase to activate it when you need it, with 24/7 support in all languages via email and WhatsApp if something doesn't go as expected.
