In short: Lowi roaming works at no extra cost within the European Union: you use your data and minutes as in Spain, with a fair use policy. However, outside Europe, things change completely, and it's good to know this before packing your bags to avoid a surprise on your bill.
What is Lowi and what network does it use?
Lowi is Vodafone's low-cost operator and runs on Vodafone Spain's network. This means coverage and speed equivalent to those of the parent brand, but with more affordable rates and no commitment period, which has made it very popular among those looking to save money.
As a virtual mobile operator backed by Vodafone's infrastructure, Lowi offers data-only plans, combined calls and data plans, and fiber plus mobile plans. Its value proposition is clear: low price and simple online contracting. That's why many frequent travelers choose it for daily use, but that same low-cost philosophy has consequences when you travel outside Spain. By relying on the Vodafone network, its roaming behavior is partly similar to that of its parent company, although international bundles are nowhere near as comprehensive. If you want to see how it compares to what other Spanish companies offer, check out our comparison of roaming prices by Spanish operator, which pits Lowi against the rest of the market.
Lowi roaming in the EU: price and limits
Within the European Union, Lowi roaming is included at no additional cost thanks to the European "Roam Like at Home" regulation. You use your data, calls, and SMS as in Spain, subject to a fair use policy that limits the volume of data in roaming according to your plan.
In practice, this covers most trips within Europe: a getaway to Lisbon, a vacation in Italy, or a weekend in Paris. The fair use limit is usually calculated based on the price of your plan, so more economical plans have a lower roaming data cap than your total contracted volume. When you exceed that limit, a small surcharge per additional gigabyte applies, within the limits set by European regulation.
These ranges vary according to the plan and are updated periodically, so it's advisable to check your specific fair use cap before traveling; consult the official operator's website for the exact data. If you want to better understand the European framework, we recommend reading what data roaming is and how it affects you depending on your destination.
Traveler tip: within the EU, you don't need to deactivate anything, but if your plan has few gigabytes, monitor map and video consumption to avoid exhausting your fair use cap halfway through your trip.
What happens outside Europe with Lowi
Here's the real problem. Outside the European Union, Lowi typically does not offer international data bundles: in many destinations, data is blocked or a pay-per-use rate per megabyte is applied, which is extremely expensive. This is the key difference compared to operators with broader global coverage.
If you travel to the United States, Mexico, Thailand, Morocco, Turkey, or the United Kingdom after Brexit, it's most common for your Lowi plan not to include usable data, or for browsing to cost you several euros for every few megabytes consumed. A simple Google Maps search, checking email, or uploading a few photos to social media can inflate your bill without you realizing it. Therefore, for destinations outside Europe, relying on traditional roaming is usually the worst economic option.
A real example of how this can escalate: downloading emails upon landing, updating Instagram in the taxi, or allowing apps to sync in the background are automatic actions that you don't even perceive as "using data," but with pay-per-use outside the EU, each of them adds up. And you don't have to go far: the United Kingdom, so close and so frequently visited, ceased to be covered by free roaming after Brexit, so a weekend in London with Lowi can turn out to be much more expensive than expected if not prepared for in advance.
The general recommendation for these cases is to disable data roaming and connect via another method. You can find our complete comparison between eSIM and roaming, where we explain in detail how to avoid these extra costs in countries outside the EU.
How to activate and deactivate roaming in Lowi
Activating or deactivating roaming in Lowi is done from the phone's own settings, not by calling the operator. In the EU, it's ready to use, while outside Europe, it's advisable to turn it off to avoid pay-per-use charges while you decide how to connect.
The process is practically identical on any modern mobile phone. On Android, go to Settings > Connections > Mobile networks and activate or deactivate "Data roaming". On iPhone, go to Settings > Mobile data > Options > Data roaming. Take that same moment to get your alternative ready: in our guide on how to install an eSIM, you'll find the step-by-step process, which takes barely two minutes.
If you want to ensure you don't pay too much when leaving Europe, below you'll find a list of myths and tricks that almost no one tells you about Lowi roaming. Remember: deactivating roaming does not turn off your line; it simply prevents your mobile from using data from the foreign network. You will still receive SMS and, in many cases, calls, although these may incur costs outside the EU.
Quick tip: before landing outside Europe, disable data roaming and activate airplane mode during takeoff. This prevents your mobile from automatically connecting to an expensive local network as soon as you turn it on.
Myths and what almost no one tells you about Lowi roaming
There are details about roaming that aren't in the fine print of any plan and that you only discover when it's already happened to you, or when someone tells you before it does. These are the ones that most often surprise those who travel with Lowi.
Andorra and Gibraltar are not "Europe" for roaming purposes
Although they are just across the Spanish border, neither Andorra nor Gibraltar are part of the European Union for the purposes of the "Roam Like at Home" regulation. If you go skiing in Andorra or cross to Gibraltar for the day, your phone might connect to a local network with non-EU rates without you expecting it. Before a weekend there, turn off mobile data and use Wi-Fi, or at least check what conditions Lowi applies to those specific territories.
Canary and Balearic Islands are not always treated the same
They are Spanish and European territory, so there is no roaming as such, but some low-cost rates apply different conditions to calls and SMS between the peninsula and the islands within the national bundle itself. If you go from Madrid to Tenerife, you won't have roaming surprises, but it's advisable to check if your minute bundle treats the call as fully national or has any separate condition before assuming everything works exactly the same.
Cruises and ferries don't count as "being in the EU"
This is one of the biggest bill generators. On the high seas, your phone can connect to a satellite maritime network that is not covered by the European roaming agreement, even if the ship is sailing between two ports within the European Union. A cruise from Barcelona to Rome can generate maritime roaming charges even if you never set foot on land outside the EU. The only safe way to avoid this is to put your phone in airplane mode while sailing and only connect to the ship's Wi-Fi if it offers it.
Roaming can reactivate itself without you knowing
If you remove the SIM, restart the phone, or there's an operating system update, some mobile phones reactivate data roaming by default. It's advisable to check this on the second or third day of your trip, not just upon landing, especially if you're going to be outside the EU for several weeks. According to available data on how Spaniards behave with roaming abroad, a good part of bill shocks don't come from a mistake when leaving, but from the phone reconnecting itself halfway through the trip.
The eSIM alternative for cheap travel
When Lowi doesn't cover you outside Europe, a travel data eSIM is the most convenient and economical solution. It's a digital card you download to your phone before you leave, choose the country or region, and connect to a local network as soon as you land, with no physical cards or surprises.
The main advantage is the price: instead of paying Lowi's roaming rates per megabyte, you buy a fixed data package for your destination with a known cost in advance. Activating it takes 1 minute: you install the profile by scanning a QR code, keep your Lowi number for SMS and WhatsApp on the main line, and use the eSIM only for data. This way, you travel connected without giving up your Spanish number.
This option is ideal precisely for destinations where Lowi falls short: America, Asia, Africa, or any country outside the European zone. You can check the eSIM plan for the United States or the eSIM for Europe (useful if you're combining countries inside and outside the EU on the same route) and choose the one that fits your trip. In short, this turns a Lowi weakness into a connected and cheap trip.
Comparison: Lowi roaming vs. travel eSIM
To see it at a glance, we compare Lowi's roaming with a data eSIM depending on the destination. The difference is minimal within the EU, but enormous once you leave Europe, which is precisely where most people get an unpleasant surprise on their bill.
| Situation | Lowi Roaming | Travel eSIM |
|---|---|---|
| Travel within the EU | Included (fair use) | Optional, not essential |
| Travel outside the EU | Data blocked or very expensive pay-per-use | Fixed package, known price |
| Activation | Automatic in the EU | Scan QR, 1 minute |
| Keep your number | Yes | Yes, as main line |
| Expense control | Difficult outside the EU | Total, pay in advance |
As you can see, within Europe, Lowi roaming is perfectly valid, and you don't need anything else. The problem arises when crossing the EU borders, where the digital card goes from being optional to almost essential. That's why it's advisable to have your connection ready before leaving and not improvise upon landing.
Frequently Asked Questions
Is Lowi roaming free throughout Europe?
Yes, Lowi roaming is included at no extra cost in European Union and European Economic Area countries, subject to a fair use policy. You use your data and minutes as in Spain. Outside this zone, this gratuity does not apply, and costs can be very high.
Does Lowi work in the United States or Morocco?
In destinations outside the EU, such as the United States or Morocco, Lowi typically does not offer data bundles: it's common for browsing to be blocked or charged on a pay-per-use basis at very high prices. For these countries, the most cost-effective option is to disable roaming and use a travel data eSIM.
How do I deactivate roaming on my Lowi mobile?
From your phone's settings. On Android: Settings, Mobile networks, and deactivate "Data roaming." On iPhone: Settings, Mobile data, Options, and turn off "Data roaming." You don't need to call Lowi; the change is immediate and avoids pay-per-use charges outside the EU.
Can I keep my Lowi number if I use an eSIM?
Yes. The eSIM works as a second line only for data, while your Lowi SIM remains active to receive SMS and calls on your Spanish number. This is the usual setup: data through the eSIM for the destination and your usual number available for verifications and WhatsApp.
How much does an eSIM cost compared to Lowi roaming outside Europe?
An eSIM is usually much cheaper than Lowi's pay-per-use outside the EU, where a single gigabyte can cost several euros. With an eSIM, you buy a fixed data package for your destination at a known price. Check the available plans to see the exact cost per country.
Does Lowi charge for receiving calls while roaming outside the EU?
Yes. Unlike within the European Union, where receiving calls while roaming has no cost, outside the EU, Lowi can charge you for both making and receiving calls while connected to a foreign network. If you want to avoid surprises, the safest option is to divert calls to voicemail or inform your contacts to reach you via WhatsApp while you're away.
What happens with Lowi roaming in the UK after Brexit?
The United Kingdom left the European "Roam Like at Home" agreement when Brexit was completed, so Lowi treats it as a destination outside the European Union: no included data bundles and a risk of pay-per-use at high prices. It's advisable to treat a trip to London exactly the same as one to the United States or Morocco in terms of preparing your connection in advance.
Conclusion
In summary: Lowi roaming covers you at no cost within the European Union with fair use, but outside Europe, data is blocked or charged at exorbitant prices. For those trips, the simplest and most economical solution is to have your connection ready in advance. Prepare your data connection before leaving and land ready without bill shocks. Activating a travel eSIM takes barely a minute and saves you pay-per-use charges outside the EU.
