What Is Data Roaming and How Much Can It Really Cost?

If you're traveling abroad or simply in areas not served by your mobile operator – such as Elisa, T-Mobile, Orange, or others – your phone will automatically switch to a partner network and start using data roaming when you access the internet. The biggest downside is the cost. In many cases, mobile data while roaming can be three to ten times more expensive than what you're used to at home.

In this article, we’ll explain what data roaming is, what kind of charges to expect, and how to avoid paying too much while staying connected.

So, What Is Data Roaming?

Data roaming is a service provided by your mobile operator that lets you stay connected to the internet even when you're outside your home network. For example, if you travel abroad on vacation, your operator connects you to a local partner network in the country you’re visiting.

Let’s say you go to Turkey. Your phone will automatically connect to a local provider like Turkcell, Vodafone Türkiye, or Türk Telekom – without needing a new SIM card. Everything works through your existing mobile plan.

Data roaming covers a wide range of online activity, including:

  • Active internet use: browsing websites, using messaging apps, watching videos;
  • Background app activity: downloading updates, syncing data, loading maps, images, or messages;
  • App-based services: mobile banking, GPS navigation, YouTube, Spotify, and more.

Data roaming does not include calls or text messages, and it won't be used if you're connected to Wi-Fi.

Here are the main disadvantages of using data roaming:

  • High costs, especially if you don’t have a special package. Rates can reach up to €1 per MB, and there’s often a limit of 100 MB to 1 GB, after which the price may increase even further.
  • Unexpected charges. Even if you’re not actively using the internet, background app activity like syncing, updates, or map loading can use a lot of data without you realizing it. These charges often show up only after the fact.
  • Reliance on a single local provider. Your phone may connect to just one local network, which can lead to weak signal, dropped connections, or coverage gaps depending on your location.
  • Slower speeds. When roaming, local operators may deprioritize your connection, resulting in slower data speeds compared to their customers.

How Much Does Data Roaming Cost?

The cost of using your phone abroad depends on your mobile provider (such as Orange, Vodafone, and others) and the country you're visiting. Often, operators classify countries into different zones:

  • Zone B: neighboring countries or nearby regions, which usually have the lowest roaming rates. For example, many European operators include Turkey and the Balkans in this zone, while for the UK, Zone B often covers EU countries. Here, rates tend to be the most affordable, and if you have a European operator, you may benefit from the “Roam Like at Home” rule within other EU countries.

Example: In summer 2025, Vodafone UK charges £2.57 per day for roaming in Zone B (Europe). For zones C and D (which include locations like Canada, Japan, Mexico, and the Caribbean) the daily roaming rate is higher, at around £7.86 per day.

  • Zone C: includes more distant countries with roaming agreements, where rates tend to be higher. This zone covers places like Egypt, Israel, the USA, and others. For example, in summer 2025, O2 charged £6 per day for these countries when using their Travel Bolt-On add-on.
  • Zone D: covers the most exotic and remote destinations, such as Africa and Oceania, with the highest roaming rates. For instance, in August 2025, Deutsche Telekom offered a DayPass S for this zone – 10 MB of data for €24.95 per day.

On average, here are some example roaming rates: Elisa charges around €0.20 per MB if you don’t activate a special tariff plan, or between €10 and €20 per 1 GB depending on the package. US operators often set roaming fees at about $10 per day. Orange offers rates of roughly €13 to €15 per MB in some countries. However, if you activate a specific tariff plan, prices can drop to around €8 to €15 per GB.

Is It Possible to Save Money on Data Roaming?

Yes, there is a great alternative – buying a prepaid travel eSIM. This virtual SIM card can be purchased entirely online in just a few clicks and provides reliable, often much cheaper internet access while you’re abroad. Savings can be up to 90%, especially when traveling to exotic destinations.

For example, with PrimaSIM, you can activate plans for Italy or Austria like these:

  • 1 GB / 7 days – $3.99
  • 2 GB / 15 days – $4.99
  • 3 GB / 30 days – $5.99
  • 5 GB / 30 days – $8.99
  • 10 GB / 30 days – $12.99
  • 20 GB / 30 days – $21.99
  • 50 GB / 30 days – $47.99

If you’re traveling to Zone C countries like Australia, these are the PrimaSIM rates for that location:

  • 1 GB / 7 days – $5.99
  • 2 GB / 15 days – $7.99
  • 3 GB / 30 days – $9.99
  • 5 GB / 30 days – $14.99
  • 10 GB / 30 days – $23.99
  • 20 GB / 30 days – $38.99
  • 50 GB / 30 days – $86.99

Planning to visit several countries? You can choose a regional plan that provides uninterrupted internet across multiple locations. For example, PrimaSIM’s North America plan (covers 5 countries) includes:

  • 1 GB / 7 days – $6.99
  • 2 GB / 15 days – $9.99
  • 3 GB / 30 days – $12.99
  • 5 GB / 30 days – $20.99
  • 10 GB / 30 days – $33.99
  • 20 GB / 30 days – $54.99
  • 50 GB / 30 days – $118.99
