Telekom Slovenije's current Mobi starter
Telekom Slovenije sells Mobi as prepaid SIM or eSIM, with the eSIM bought and activated through its Moj Mobi app. The operator's current Mobi product page says the €2 starter provides seven days of unlimited calls within the Telekom Slovenije network and 1 GB of data in Slovenia. The word unlimited refers to those on-network calls, not to mobile data. This distinction matters if you expect to navigate between Ljubljana, Lake Bled and a rural guesthouse throughout the week.
Mobi's support material still refers to older unlimited-data starter cards available at shops only while stocks last. That older offer is not the same as the current €2 starter described above. Check the package shown in the app or printed on the physical card at the time of purchase. For a data-heavy holiday, the current starter's 1 GB is likely a starting allowance rather than a whole-trip solution; examine the available add-on or a different prepaid pack before relying on it.
Telekom says the Moj Mobi app can add credit by payment card or voucher and manage multiple Mobi numbers. Physical cards and vouchers are also sold through Telekom centres and authorised sales points. Its Mobi FAQ explains that a top-up begins a ninety-day active period for the account; after that it temporarily locks until recharged. This lifecycle is useful for a return visit, but a new tourist should focus on the seven-day starter and any additional data needed during the present trip.
A1 Simpl for a weekend or a longer stay
A1 Slovenija's Simpl range starts with a physical card sold at A1 outlets and partners that include Petrol, MOL and Shell service stations, Slovenian post offices, Mercator and other listed retailers. The card activates on its first call, text or data connection and comes with a short three-day Simpl mini allocation. That makes it practical for a traveller arriving by car at a service station, but it also means that a test connection can start the initial period before the main holiday begins.
The operator's current prepaid page lists Simpl mini with 2 GB and 2,000 combined minutes or messages for thirty days, Simpl maksi with 100 GB in Slovenia and unlimited domestic minutes or messages for thirty days, and Simpl net with 100 GB in Slovenia for ninety days. At the time of checking, the advertised package prices were €2.99, €6.99 and €9.99 respectively. A1 describes up to 2 GB of EU or EEA use for mini and 13.4 GB for maksi; the 100 GB figure on maksi is a Slovenian allowance, not a promise of 100 GB across Europe.
The operator says these packages renew automatically if the prepaid account has enough credit, and unused or exhausted amounts are charged according to the underlying Simpl rate. That deserves attention if you leave the SIM active after a short visit. Use the Moj A1 app or its listed top-up channels to watch the balance, and check whether the card or a newly purchased package is the one whose clock is running.
What EU roaming covers on this itinerary
The European Commission includes Slovenia in the EU roam-like-at-home area. If your home subscription is from an eligible EU or EEA country and the trip is periodic, using it in Slovenia normally draws on domestic calls, texts and data terms. Unlimited or unusually cheap data may have a fair-use allowance when abroad, and the home operator should explain it. Read the provider's welcome message at the Slovenian border before buying a second plan just for Ljubljana or Bled.
A locally purchased Slovenian line has its own roaming details. A1 Simpl mini and maksi publish smaller EU or EEA data allowances than their domestic data allowances. Telekom Slovenije's Mobi FAQ says a user must register in Moj Mobi and demonstrate permanent ties to Slovenia to use package units while EU roaming; an unregistered user may face surcharges. That condition makes Mobi a poor line to assume will cover a multi-country holiday simply because Slovenia is an EU member.
This matters on common drives across the Italian, Austrian and Croatian borders. A1's Simpl net description gives 100 GB in Slovenia, without the same clear included EU data amount shown for mini and maksi. Select a product by its published cross-border allocation, not by the domestic headline. If you already have an EU home line, compare its fair-use terms before adding a Slovenian number.
Look up the route, not just Ljubljana
Slovenia's tourism board says visitors can buy prepaid cards from the main operators and lists airports, kiosks, electronics shops and petrol stations as possible outlets. It describes broad mobile signal coverage, but that general guidance cannot answer whether your specific walk, gorge or mountain accommodation has usable data. Slovenia's geography makes the exact location more important than a national slogan about network quality.
The national communications agency AKOS explains that its Geoportal carries geographic data on fixed and mobile network coverage. Use it to investigate the places you will actually visit, and compare it with the operator's own current map if that is available. The interactive map did not fully render in our check, so this guide does not claim a measured signal level for any named valley or rail route. Ask a remote accommodation for its practical experience if reliable connection is essential.
A phone's band support and the selected plan also matter. Check that an imported handset is unlocked before buying a second operator's SIM or eSIM. Where the journey involves tunnels or mountain roads, save the route and accommodation details for offline use; a coverage map is planning evidence, not a guarantee of service in transit.
Rail tickets and eSIM setup before departure
Slovenian Railways says domestic tickets can be bought online or in its Grem z vlakom app. App tickets appear in My Tickets and show a code for staff to scan aboard the train. The operator asks passengers to check timetable disruptions and replacement buses before purchasing, using its timetable finder or the app's delays area. A data connection is useful for that last-minute check on a Ljubljana to Bled or Ljubljana to Maribor journey, but save the ticket on the phone before boarding.
If you buy a local Mobi eSIM, install Moj Mobi and confirm phone compatibility while you have a stable connection. Apple says supported Dual SIM iPhones can retain a home number for calls and messages while a different line supplies mobile data, provided the device is unlocked for two providers. Set the intended data line deliberately after arriving and review the home line's roaming setting; otherwise a working eSIM may still leave the wrong line paying for background traffic.
For a short visit, compare three paths: retain an eligible EU home plan, buy a Slovenian prepaid card at a known retailer, or activate a compatible eSIM. The best choice follows how much data you need after the initial allowance, whether you need a Slovenian number and whether you will cross another border.
Calls for help and the final pre-trip check
The Slovenian government identifies 112 as the common emergency number for medical help, fire and rescue, including mountain and cave rescue. It also lists 113 for police. Keep a voice-capable way to call if the chosen travel profile is data-only; an internet connection alone is not the same as ordinary emergency voice service. Save these numbers and the address of a mountain base before setting off, especially if a local guide or accommodation may need to give directions to responders.
Check the current prepaid page again at purchase. Telekom's older Mobi promotional wording remains visible in some indexed material, but its live product page now describes a 1 GB starter. A1's Simpl card has an initial three-day period, while its later packages run longer and can renew with sufficient credit. Record the activation date and note how each line will behave when you leave Slovenia.
