In short: Simyo roaming works without extra cost within the European Union, included in your usual plan up to its reasonable use limit. Outside the EU, however, it is charged per use or through zone-based add-ons, with prices that can skyrocket in a couple of days. For those destinations, a travel eSIM is usually cheaper and allows for controlled spending from the first minute.
If you have Simyo and are going to travel, the big question is how much it will cost you to use your mobile phone abroad. The short answer: within the European Union, you browse with your usual plan, but outside Europe you pay per use and the bill can skyrocket without you realizing it. Here we break it down with data from 2026.
How does Simyo roaming work?
Simyo is a virtual operator that uses Orange's network. Within the EU, roaming is included with your plan; outside Europe, you switch to pay-per-use or pre-contracted add-ons. Check the official operator's website for exact details.
When you leave Spain, your mobile phone disconnects from the Orange network and connects to a local network in the destination country. This "borrowed" connection is what is charged as roaming. Simyo, being an MVNO, does not have its own network abroad: it depends on Orange's wholesale agreements with operators in each country, and that determines what is included and what is charged separately.
The key is to understand the boundary between two worlds. On one hand, the zone regulated by Brussels (the 27 EU countries plus some associated ones), where "roam like at home" is the norm. On the other, the rest of the planet, where there is no regulation to limit prices and each operator sets its own rates. If you want to understand the basic concept well, it will help to read what data roaming is before continuing. Simyo applies this logic just like the rest of Spanish operators, with the advantage of low-cost plans but the same rules of the game outside Europe.
Simyo roaming prices in the European Union
Within the EU, Simyo applies the "roam like at home" principle: you use your contracted plan's gigabytes, minutes, and SMS without surcharges. You don't pay extra to browse in France, Italy, or Portugal just as you would in Madrid, within the reasonable use policy limits set by your plan.
The important nuance is the limit of roaming gigabytes that the fair use policy activates. European regulations allow operators to set a data cap for roaming based on the price of your plan: the cheaper it is, the fewer "free" gigabytes abroad. If you exceed that threshold, Simyo may apply a small surcharge per additional GB, regulated by Brussels and reviewed downwards each year.
| Zone | Data | Calls | Typical extra cost |
|---|---|---|---|
| Spain (home) | Your plan | Your plan | €0 |
| EU / EEA | Included (up to cap) | Included | €0 up to the limit |
| EU, after cap | Regulated surcharge per GB | Included | Few € / GB |
| Outside EU | Pay-per-use or add-on | Per-minute rate | High without add-on |
These figures are indicative ranges for 2026; consult the official operator's website for exact data, as the reasonable use cap depends on your specific plan. For most European getaways of one or two weeks, you will not reach this limit and will not pay anything extra.
Simyo roaming outside the EU: pay-per-use and add-ons
This is the dangerous territory. Outside the European Union, "roam like at home" does not exist: every megabyte is charged at an international roaming rate, which can be several euros per MB in destinations like the United States, Morocco, Turkey, or any country in Asia and Latin America.
To get an idea of the jump: a single video or a couple of maps loaded without control can result in a bill of tens of euros in non-EU destinations. That's why Simyo, like other operators, offers data add-ons for certain zones, which reduce the price per GB in exchange for contracting them before or during the trip. Even so, they are usually more expensive and have fewer gigabytes than a specific travel solution.
Golden rule: outside the EU, assume that pay-per-use is extremely expensive. If you don't contract an add-on or an alternative, the safest thing is to travel with roaming data deactivated.
Simyo add-ons vary by country and usually cover a limited number of gigabytes for a few days. The problem is twofold: zone coverage doesn't always include your exact destination, and the cost per GB is still high compared to other options. If you're concerned about the bill, it's worth checking the eSIM vs. roaming comparison first. For long trips or to several countries, Simyo's pay-per-use rarely pays off.
How to activate or deactivate roaming on Simyo
Activating or deactivating roaming on Simyo is done from your mobile phone and takes 1 minute. You don't need to call customer service for basic use within the EU, although it's a good idea to check your customer area if you're going to contract an add-on for outside Europe.
These are the general steps on most phones:
- Open Settings > Connections / Mobile network on your phone.
- Go to Data roaming or Roaming data.
- Activate it if you want to use data abroad; deactivate it to avoid any consumption.
- For destinations outside the EU, contract the corresponding add-on from your Simyo customer area beforehand if you're going to need it.
The process is almost identical for any Spanish operator, so if you're coming from another company, it will sound familiar. If you also want to know how much other operators charge for the same concept, we have the comparison of roaming prices by Spanish operator for 2026. And if what you're looking for is just the opposite, to shield yourself from spending a single cent, take a look at what a virtual eSIM is and how it works. Deactivating roaming is your best insurance against a surprise bill in non-EU countries.
Tips to avoid bill shock
Most roaming shocks don't come from misuse of the mobile, but from not having configured anything before leaving. With four basic precautions, you reduce the risk almost to zero, whether you're traveling to Berlin or Bangkok.
These are the practices that save the most:
- Activate consumption alerts if your plan allows it, so it notifies you when you're approaching your roaming data limit.
- Download offline maps (Google Maps offline) before traveling: browsing consumes the most data.
- Deactivate background updates and automatic photo and cloud syncing when roaming.
- Use Wi-Fi whenever possible in hotels, cafes, and airports for heavy downloads.
- Have an alternative ready for destinations outside the EU, instead of relying on pay-per-use.
Even with all this, relying on a borrowed local network carries a risk. That's why many travelers opt for internet without depending on their home operator's roaming. If this route interests you, we've explained how to install an eSIM step-by-step, a process done before leaving home and where you don't need to touch your Simyo line. The idea is simple: separate your home line from your travel data so an oversight doesn't cost you money.
Myths about Simyo roaming that almost no one tells you about
There are several ideas about roaming that are taken for granted and, in practice, cause more than one upset. Here are the ones that most often catch people by surprise.
"If my plan is unlimited, I also have unlimited data when roaming in the EU." Not exactly. The reasonable use limit set by Brussels is calculated by dividing the price of your plan by a reference wholesale price that is reviewed annually, so the cheaper your Simyo plan, the sooner you reach the roaming cap, even if at home you consider it "unlimited." This is not a Simyo trick: the entire industry applies it by regulation.
"My mobile always connects to the network with the best coverage in the country." Not true either. When roaming, the phone usually connects to the first available network or the one that has a priority agreement with Orange in that country, not necessarily the one that provides the best signal exactly where you are. If you notice a weak connection as soon as you land, go to Settings > Mobile network > Network operators, deactivate automatic selection, and manually try another network in the country. This changes more than people think, especially in rural or border areas.
"If I turn off mobile data, they can't charge me anything." Be careful with this one. Outside the EU, incoming calls and SMS are also billed separately and do not depend on the roaming data switch: they still ring and still cost even if you have data roaming deactivated. If you are going to a destination with high rates, also check the voice and messaging section, not just the data.
Another detail often overlooked: the destination matters, and a lot. The cost and coverage of Simyo roaming are not the same in Morocco as in the United States or a Latin American country, because they depend on which local operator has an agreement with Orange in each location. If you are crossing the Atlantic, take a look at our guide to roaming in Latin America by operator, and if the destination is the United States, keep in mind that pay-per-use there skyrockets particularly quickly; you can directly check the eSIM for the United States as an alternative before leaving. And if you are interested in the general context, there are curious facts in our analysis of roaming statistics for Spaniards abroad: roaming continues to be one of the most underestimated travel expenses.
Alternative: Travel eSIM versus Simyo roaming
A travel eSIM is a digital SIM that you download to your mobile phone and that gives you data for your destination country at local prices, without affecting your Simyo line. For trips outside the EU, it is usually much cheaper and more predictable than pay-per-use or operator add-ons.
The great advantage is peace of mind: you contract a gigabyte package for your destination, you know exactly what you're going to pay, and your Simyo number remains active to receive bank SMS and important calls. There are no surprises at the end of the month, nor any need to request zone add-ons that may not cover your country. Activation is done via QR in 1 minute and you start browsing as soon as you land.
| Option | Cost outside EU | Cost control | Keep your number |
|---|---|---|---|
| Simyo Roaming (pay-per-use) | Very high per MB | Low | Yes |
| Simyo Add-on | Medium-high per GB | Medium | Yes |
| Travel eSIM | Low, local price | Total | Yes (separate line) |
For Europe, Simyo roaming already covers you, and you don't need anything else. But for destinations outside the EU, comparing before traveling makes all the difference. You can see the available options in our travel eSIM store and choose the package that fits your destination and your days.
Frequently asked questions
Is Simyo roaming free throughout Europe?
In the European Union and the European Economic Area, you use your plan without surcharge, within the reasonable use limit set by your plan. If you exceed that gigabyte cap, Simyo may apply a small per-GB surcharge regulated by the EU. Consult the official operator's website for your specific case.
How much does it cost to use Simyo outside the EU?
Outside the European Union, the cost is pay-per-use, with high per-MB rates that vary greatly depending on the country. Simyo offers add-ons for some zones that make the price cheaper, but they are still more expensive than a travel eSIM. The safest option is to deactivate roaming and contract an alternative.
How do I deactivate roaming on Simyo?
Go to Settings, Mobile Network or Connections, and deactivate the Data Roaming option. This stops any data consumption abroad. It takes 1 minute and is the most reliable way to avoid a surprise bill in destinations outside Europe.
Can I use an eSIM and keep my Simyo line?
Yes. The eSIM works like a second digital line on your mobile. You use the eSIM data to browse at local prices and keep your Simyo number active to receive important calls and SMS, such as bank codes. You only need an eSIM-compatible phone.
Is an eSIM more cost-effective than Simyo roaming?
For travel within the EU, no, because Simyo already includes usage without surcharge. For destinations outside Europe, a travel eSIM is almost always cheaper and more predictable than pay-per-use or add-ons, and gives you total control over spending.
Conclusion
In summary: with Simyo, you travel worry-free throughout the EU using your usual plan, but outside Europe, pay-per-use is expensive and it's advisable to deactivate roaming or look for another option. Add-ons help, though they rarely match a specific travel solution. Before your next trip outside the EU, compare options and forget about surprise bills.
