If you have traveled to another country, you should know how chaotic it is to not be able to make calls or connect to the internet, due to not having direct coverage with your telephone company.Fortunately, the progress made in international agreements between operators greatly facilitates connectivity when we travel abroad, both within the European Union and to other destinations. This connection system is what we call data roaming o roaming .
Currently, when you travel to countries with which your carrier has agreements, calls and internet browsing generally remain the same price as your national rate, especially within the European zone. However, when you leave the EU If you're traveling to special areas, activating data roaming can incur high costs if you don't take the proper precautions. Therefore, it's essential to fully understand how roaming works, how and when to activate it, and what practices to follow to avoid unexpected bills.
What is data roaming or roaming and what is it for?
La data roaming, internationally known as roaming , is a service that allows mobile phone users to continue using their line for calls, text messages, and internet access outside their carrier's coverage area, typically when traveling to another country. When the phone detects that it's outside its carrier's network, it automatically connects to a local network with which your carrier has partnered.
This service is regulated within the European Union, which means that, under certain conditions, you can browse and call with the same national rates. However, when you leave the EU or you travel to special areas, the rates may be different and much higher.
Data roaming is key to maintaining connectivity while traveling, as it allows you to:
- Internet access and applications such as maps, email or social networks abroad.
- Make and receive calls and SMS outside your usual network.
- Check essential information (flights, reservations, addresses).
- Working or studying remotely during temporary stays in other countries.
However, it should be noted that the costs and conditions of roaming depend on several factors:
- El destiny country and its tariff relationship with your operator.
- La fair use policy in force in the European Union and associated countries.
- The specific agreements between operators.
- The type of rate contracted (prepaid, contract, unlimited plans, etc.).
In some cases, especially outside Europe, you'll receive an SMS from your carrier upon crossing the border, informing you that roaming has been activated, the applicable charges, and any relevant fair usage policies or limitations.
How data roaming works: zones, rates, and conditions
El roaming operation It depends on the location and the network you connect to:
- Within the European Union and associated countries such as Liechtenstein, Norway, Iceland and the United Kingdom: the 'roaming like at home' policy applies, whereby your national rate remains the same for calls, SMS and data, except in cases of abusive use or certain limits (e.g. maximum GB at maximum speed on unlimited plans).
- In countries outside the EU (zones 2 and 3 depending on the operator): roaming is not free, and rates for calls, text messages, and MB consumed are usually significantly higher.
Example of zone grouping for roaming:
- 1 Zone: EU countries, Norway, Iceland, Liechtenstein, the United Kingdom, and associated territories. Cost equal to your national rate.
- 2 Zone: Countries such as the USA, Canada, Switzerland, Andorra, Türkiye, Morocco. Special rate not regulated by the EU (check before traveling).
- 3 Zone: rest of the world, much more expensive rates.
The division may vary slightly depending on the operator, and some operators such as Vodafone include exceptions in specific areas. Before any trip, it is essential to check the roaming rate table from your company and, if possible, hire special packages for the destination country.
How to enable data roaming step by step on Android
Enabling data roaming on Android is very simple, although the exact location of the option may vary depending on the system version and device brand. Here are the most common steps:
- Access the Settings of your mobile.
- Sign in Network and Internet o SIM card and mobile networks (depending on the phone).
- Look for the option Data roaming o data roaming.
- Activate roaming, confirming the notice that additional charges may apply.
- For more detailed management, some operators allow you to control roaming from their official app or customer area website.
Remember that with some virtual mobile network operators (MVNOs), you may need to activate roaming even when you're in the same country, as they use third-party networks to provide service.
How to turn roaming on or off on iPhone
The process on Apple devices is similar, although the names of the options change:
- Go to Settings.
- Sign in Mobile data and then Options.
- Turn on or off the Data roaming.
Most cell phones also allow you to set mobile data alerts or restrictions to prevent unintentional data usage when crossing borders.
When to activate data roaming? Tips based on the type of trip
Data roaming should be activated in these cases:
- When you travel to a country outside of national coverage and need to stay connected (for calls, maps, messaging, etc.).
- If you use a virtual mobile operator (MVNO) and coverage in your area depends on a third-party network.
- When your destination is within the European Union and your fare allows it, without any additional costs.
However, there are circumstances where it is advisable to deactivate roaming:
- You are traveling to a country outside the EU or Zone 1 without an international data plan.
- Do you want to avoid unexpected charges for data or call usage.
- You intend to use only WiFi, without consuming your data plan on foreign networks.
It's important to remember that some apps can consume data in the background even when you're not actively using them, which can increase your bill if you have roaming enabled.
Is it safe to use data roaming?
Data roaming is technically secure, but involves taking economic risks If usage is not monitored or rates have not been checked beforehand. The phone, by automatically connecting to the available local network, can quickly consume data if it updates apps, uploads photos, or performs automatic syncs.
On the other hand, information security while roaming depends on the usual protection measures: using encrypted connections (HTTPS), not accessing unprotected public Wi-Fi networks, and avoiding transmitting sensitive data when not necessary.
Some practical tips to reduce risks:
- Set your mobile data usage limit in your Android or iPhone settings.
- Turn off automatic app updates and syncing.
- Use WiFi whenever possible and ensure the network is reliable.
- Check your provider's messages, as they often warn of conditions or limits on fair use.
How data roaming affects WhatsApp and other apps
WhatsApp uses your mobile data plan, so all communication (messages, calls, file transfers, video calls) during roaming This involves data usage under the roaming rate. If roaming is active outside the European zone or without a roaming plan, receiving or sending messages may incur charges, especially if you exchange photos or videos, or make calls or video calls.
Other services and apps, such as email, maps, cloud services (Google Drive, OneDrive), and social media, will also consume data based on usage. It's recommended to manually manage which apps are allowed to use data while roaming in your phone's advanced settings.
If you only want to use WhatsApp over Wi-Fi, disable roaming and enable airplane mode by connecting to secure wireless networks.
The case of virtual mobile operators (MVNOs)
The virtual mobile operators Mobile Network Operators (MVNOs) don't have their own network infrastructure and rely on agreements with major carriers to provide mobile coverage. Therefore, you often need to keep data roaming active even within your country of residence. If you've recently switched to an MVNO and are experiencing connection issues, it's likely necessary to enable this feature.
Differences between international and national roaming
It is important not to confuse:
- International call: The user is in their home country and makes a call to a foreign number. Special charges apply.
- Roaming: The user is physically located outside their home country and uses local networks to communicate. Calls, SMS, and data charges may vary.
Within your country, if you change networks due to loss of coverage, roaming is usually automatic for MVNOs, at no extra cost. Abroad, any roaming usage will depend on operator agreements and tariff zones.
What limits and conditions apply to roaming in Europe?
The European roaming regulation establishes that:
- Call, SMS, and mobile data roaming rates within the EU, Norway, Liechtenstein, and Iceland must be the same as domestic rates.
- Fair usage policies apply: If you exceed the level of usage considered "normal" for a typical user, the operator may apply surcharges after notifying you in advance.
- Common examples of limits: around 50 GB on unlimited plans outside of Spain or your country of residence; beyond this limit, each MB or GB carries a moderate surcharge.
- Operators can control the proportion of time a user spends abroad compared to their nationality over a four-month period to prevent abuse.
How to avoid high charges on your bill when using data roaming
To avoid bill shocks when using mobile data outside your country, consider these practical tips:
- Always consult your telephone operator about rates, plan conditions, and included countries before your trip.
- Connect to WiFi networks secure whenever possible, especially for large downloads or video calls.
- Use applications that compress data, such as Lite mode in Chrome, Opera Mini or other apps that limit consumption.
- Consider purchasing one local SIM card prepaid at your destination for affordable data and calls within the country.
- Set alerts or data usage limits on your phone to avoid exceeding your desired amount.
- Turn off data roaming when you don't need it or if you'll only be using your phone for urgent calls and text messages.
- Find out if your operator offers international data bonuses or special packages for travelers.
- Disable automatic download of media files in WhatsApp or other apps while roaming.
- Make sure system updates, photos, and videos are uploaded only over Wi-Fi.
Roaming on airplanes and ships: precautions
On trips by boat or plane, mobile services can connect to satellite networks whose cost is much higher than that of terrestrial networks in zone 1. Always use the WiFi network on the plane or ship (where available) and be sure to turn off data roaming if you don't want unexpected charges.
What happens if I exceed my rate or fair usage limits?
If you exceed the fair usage limits set by your operator while roaming (for example, using more GB than allowed or spending more time abroad than in your home country), you may receive a warning and subsequently incur charges:
- Voice call limits: per-minute surcharge based on EU regulations.
- SMS Limits: Message Surcharge.
- Mobile data limit: extra charge for each additional MB or GB outside of the allowance or reasonable usage.
In most cases, if you need to continue browsing after exceeding your limit, you must notify your operator or manually activate the bonus extension.
