The Cheapest Data Bundles for Roaming in Europe

Whether for a day trip or a longer holiday, many of Switzerland’s residents frequently travel to other European countries. Many Swiss mobile service providers offer data roaming bundles that enable phone users to stay online while traveling in Europe. This moneyland.ch guide gives you all the most important information about data roaming in Europe, and explains how to find the right data bundles.

How can I use data roaming in Europe?

There are three different ways to use data roaming, but not all Swiss mobile carriers offer all three of these.

• Mobile plan with included roaming allowances: Some mobile plans include a certain amount of roaming data that can be used to get online in certain countries.
• Data roaming bundle: These optional bundles can be added to mobile plans to enable you to get online. This is useful if your plan does not include roaming data or the included allowances are used up, or if the included roaming allowances do not apply to the country you are travelling to.
• Roaming at standard rates: Some carriers let you use roaming even if you do not have eligible roaming allowances or data bundles. They apply a standard roaming fee schedule to determine the rates you pay. Roaming at standard rates is generally not advisable because the costs per megabyte are very high. Spusu is an exception to this rule, as its standard roaming rate for Europe is relatively modest at 0.4 centimes per megabyte (3.91 francs per gigabyte).

Which European countries are covered by data roaming bundles for Europe?

Each Swiss mobile carrier has its own definition of Europe. The data bundles offered by Swiss carriers cover all EU countries, plus the UK, and Norway. Since 2026, the Europe zones used by Salt, Gomo, Lidl Connect, Post Mobile, and Sky Mobile also include all EU countries.

Sunrise and other carriers that use the Sunrise network include Turkey in their Europe zone. Swisscom, Coop Mobile, Migros Mobile, Wingo, and Spusu include Ukraine in their Europe zone. M-Tel also includes the Balkan countries of Bosnia and Herzegovina, Montenegro, North Macedonia, and Serbia in the Europe zone.

The table below shows you which countries are covered by the Europe bundles from different mobile carriers.

For its analysis, moneyland.ch accounted for 40 European countries. Most Swiss carriers include 30 to 33 countries in their Europe zones – around three quarters of the countries accounted for in the analysis.

Which data roaming bundles should I use for travel to European countries?

Most Swiss mobile service providers offer three different data bundles for roaming in Europe, but depending on the carrier, the selection may be larger or smaller than that. Roaming data bundles from Swiss carriers are normally valid for one year, partly because of legal requirements.

The cheapest data bundles for roaming in Europe cost less than 10 francs. In most cases, these contain one gigabyte of data. Currently, the biggest roaming bundles with a validity period of one year have 20 gigabytes of data.

The diagram below shows you how much you would pay for between 1000 and 10,000 megabytes (1 to 10 gigabytes) of data per year. The amounts shown are based on the cheapest combinations for each data amount.

Which are the best data bundles for Balkan countries?

Data roaming is easiest in the EU countries of Greece, Croatia, and Slovenia. All Swiss providers classify these countries as part of the Europe zone. 
In the other Balkan countries, the situation is more complicated. With most Swiss mobile providers, data roaming in the Balkans is significantly more expensive than in EU countries. M-Tel and Spusu are exceptions.
M-Tel, however, also includes the Balkan countries of Bosnia and Herzegovina, Montenegro, North Macedonia, and Serbia in its Europe zone. Although Albania and Kosovo are assigned to a different zone, M-Tel is comparatively inexpensive there as well.

Although Spusu does not offer data roaming bundles, its data roaming rates in some Balkan countries are lower than those of its competitors. For example, one gigabyte costs 2 francs in Bosnia and Herzegovina, North Macedonia, and Serbia, while in other Balkan countries, the price can be as high as 7 francs for one gigabyte.

With other Swiss providers, data roaming in the Balkan countries that are not part of the EU is significantly more expensive.

Which are the best data roaming bundles for other European countries?

Other European countries may fall into one or multiple zones, depending on the carrier. Sunrise, Digital Republic, and Galaxus Mobile include Turkey in their Europe zone. Digital Republic charges 35 francs for 10 gigabytes, and Sunrise charges around 48 francs. Swisscom and Salt both charge 50 francs for a country-specific bundle, with the difference being that Swisscom's bundle includes 10 gigabytes of data, while Salt's includes 20 gigabytes.

Spusu doesn't offer data bundles, but it has by far the cheapest offer for internet access in Turkey: One gigabyte costs 2 francs, so 10 gigabytes costs a total of 20 francs. Data roaming in Turkey is also relatively inexpensive with M-Tel: A 10-gigabyte bundle costs just under 30 francs.

Ukraine is another example. Swisscom, Coop Mobile, Migros Mobile, Spusu, and Wingo include Ukraine in their Europe zone. 10 gigabyte of data roaming in Ukraine costs 40 francs with Spusu, nearly 50 francs with Swisscom (with a country bundle) and Sunrise. With a Europe bundle, the price is just under 60 francs with Swisscom. Salt charges just short of 60 francs for a 20-gigabyte bundle with a one-year validity term.

Which Swiss carrier has the cheapest data bundles for Europe?

moneyland.ch calculated the average price per gigabyte for data roaming in EU countries based on amounts of data between 1000 and 10,000 megabytes (1 to 10 gigabytes) in 100-megabyte increments. The calculations also account for the fact that consumers may have to buy bundles with more data than they actually need.

M-Tel is the cheapest, with average costs of 2.29 francs per gigabyte, followed by Spusu with 3.91 francs. In third place is Digital Republic with an average price of 5.35 francs. Next in line are Coop Mobile, Migros Mobile and Wingo (6.24 francs each) as well as Sunrise (6.82 francs) and Swisscom (8.41 francs). Salt, Gomo, Lidl Connect, Post Mobile, and Sky Mobile are more expensive, with an average cost of 10.36 francs per gigabyte for bundles with a one-year validity term.

The average cost of using a country-specific data bundle from Swisscom in a European country is 5.34 francs per gigabyte. But it is important to note that these bundles are only valid for use in a single country, and therefore cannot be compared with bundles that can be used in an entire zone.
