SHARE RELEASE:
Key statistics for 2nd quarter 2025
Compared to the same period of 2024, Slovenian mobile phone users while roaming in foreign mobile networks:
In the same comparison, foreign mobile phone users while roaming in Slovenian mobile networks:
In June, over 10,000 different Slovenian mobile phone users recorded in 14 countries
In the 2nd quarter of 2025, Slovenian mobile phone users (hereinafter: users) travelled to 169 countries as multi-day visitors (tourists), as same-day visitors or as transit passengers. In each of the three months of the quarter, the largest number of Slovenian mobile phone users travelled to Croatia, followed by Italy, Austria and Germany.
In June, more than 10,000 different Slovenian users were registered in 14 countries. In addition to the mentioned three neighbouring countries and Germany, in Bosnia and Herzegovina, Hungary, France, Serbia, Czechia, Spain, Greece, the Netherlands, Belgium and Slovakia.
Slovenian mobile phone users as tourists spent abroad almost 13 million days
In the 2nd quarter of 2025, mobile phone users travelled as tourists (multi-day visitors) to 145 countries, where they spent together between April and June almost 13 million days, which is 5% more than in the same period last year. They spent three quarters of those days (74% or 9.6 million) in four countries: Croatia, Germany, Austria and Italy. The number of tourist days increased in Croatia by 21%.
Same-day visits to Croatia, Austria and Italy up, to Hungary down
Slovenian users most often travelled to neighbouring countries also as same-day visitors. The data on same-day visits also include non-touristic same-day visits (i.e. daily work migrations). They went on almost 3.2 million same-day visits, which is about the same number of same-day visits compared to the same period last year. 52% of those visits were half-day visits (6-12 hours), and 48% were same-day visits (12-18 hours).
They most often visited Croatia (more than 1 million same-day visits or 4% more than in the same quarter of the previous year). The number of same-day visits to Austria also increased by 4% (871,000) and to Italy by 3% (539,000). The number of same-day visits to Hungary was a lot lower (85,000) and it decreased by 3%.
The largest number of same-days visits to Croatia, Italy and Hungary was recorded in June, and to Austria in April.
Almost 6.5 million foreign users of mobile phone services roamed in Slovenian mobile phone networks in June
Mobile phone users from 139 countries visited Slovenia in the 2nd quarter of 2025. Slovenian mobile operators registered the largest number of foreign mobile phone users in June (almost 6.5 million) and the lowest in April (almost 4.6 million). Compared to the same quarter of the previous year, the number of foreign users increased in April and June (by 9% and 15% respectively), while in May it went down by 4%.
The largest number of foreign users from Austria, in June from Germany
In April and May, the largest number of foreign users came from Austria (788,000 and 984,000, respectively). In April, almost one in six and in May one in five foreign users was from Austria. In June, the largest number of foreign users came from Germany (more than 1.3 million or 21% of all foreign users).
Foreign mobile phone users in Slovenia made slightly more transit trips
In all the countries from where most foreign users came, transit passengers (stayed in Slovenia for less than 6 hours) represented the highest share of all users from a particular country.
In the 2nd quarter of this year, they made a total of 26.5 million transit trips or 3% more than in the same quarter a year ago.
More same-day visits of users from Austria, Croatia and Hungary, fewer from Italy
Austrian users made almost 1.3 million same-day visits to Slovenia in the 2nd quarter of 2025 or 29% more than in the same quarter of 2024. Croatian users made 757,000 same-day visits (24% more) and users from Hungary almost 300,000 same-day visits (14% more). Same-day visits of mobile users from Italy decreased by 1% (696,000).
Compared to the same period of 2024, Slovenian mobile phone users while roaming in foreign mobile networks:
- Spent 5% more days as multi-day visitors (tourists),
- Made 6% fewer transit trips and
- Went on about the same number of same-day visits, 1% fewer half-day and 1% more same-day ones.
In the same comparison, foreign mobile phone users while roaming in Slovenian mobile networks:

METHODOLOGICAL NOTE
The data are published as experimental because the survey is new and because the measuring instrument, the methodology of data collection and the indicators are still being developed.
Some mobile operators still have problems with (correct) coding of users by countries. Data on users can include besides mobile phones also data on other smart devices. In addition, data can also include usage of mobile phone networks by devices that connect and exchange data with other devices (Internet of Things).
The usage of eSIM cards, which are offered by mobile phone operators in the EU, is counted to the country of the mobile phone operator that provides eSIM card service and not to the country from where foreign mobile phone users are actually coming.
As there are many methodological and definitional inconsistencies between the surveys, mobile operators' statistics, which in this case are cited as experimental statistics, and statistics of other official surveys on tourism statistics, cannot be compared directly.
As part of the mobile operators' statistics, an individual is defined as a user of a mobile device roaming in a foreign network during the trip. In order to be recognized as a "traveller", they must therefore have an active mobile device, which is not a requirement in the case of other surveys.
Mobile operators' statistics also do not contain other details about individuals' trips (e.g. the reasons for travel) on the basis of which it is determined whether an individual visit is actually a "tourist" visit or not. It is highly possible that data on one-day visitors who travel between Slovenia and neighbouring countries included many of those that are otherwise not taken into account within tourism statistics (e.g. daily work migrants, truck drivers in transit, etc.).
Additional explanations are available in the methodological explanations.
