What is a mobile SIM plan in Slovenia?

A mobile SIM plan in Slovenia gives you calls, texts and mobile data on the national networks, either as a monthly contract (naročnina) or prepaid (predplačniški) top-up. Contracts often bundle generous or unlimited data, EU roaming and sometimes a subsidised handset, while prepaid suits light or flexible users with no commitment. Slovenia has strong 4G and expanding 5G coverage, and eSIM support is widely available. Plans include EU roaming under the EU's roam-like-at-home rules.

How the Slovenian market works

Mobile services are regulated by the Agency for Communication Networks and Services (Agencija za komunikacijska omrežja in storitve, AKOS). Several operators run their own networks, and virtual operators (MVNOs) resell capacity. Competition centres on data allowances, 5G access, EU roaming and bundle discounts when you combine mobile with home internet or TV. Number portability lets you keep your number when switching, and prepaid SIMs are easy to buy and register.

Benefits

Flexible options — choose a contract for the best value or prepaid for no commitment.

EU roaming included — use your allowance across the EU at no extra cost under roam-like-at-home.

5G and eSIM — access faster 5G where available and activate an eSIM instantly.

Bundle savings — discounts when combining mobile with home internet or TV.

How to choose

Estimate your monthly data use and pick an allowance with headroom, checking 5G availability in your area. Decide between contract and prepaid based on how much flexibility you want, and compare EU roaming and any non-EU roaming rates if you travel widely. Look at bundle discounts if you already take home internet or TV, and check number portability and contract length before switching.

Leading providers in Slovenia

Telekom Slovenije is the incumbent operator with the widest coverage and 5G reach. A1 Slovenia, part of an international group, competes strongly on data plans and 5G, while Telemach offers mobile alongside cable broadband and TV bundles. T-2 is a Slovenian challenger known for competitive pricing and convergent packages. Several MVNOs also operate. Comparing at least two operators on data, 5G coverage and bundle discounts is the practical approach.

What it costs

Prepaid packages and SIM-only contracts commonly range from around €5 to €30 per month depending on data allowance, with unlimited-data plans at the higher end. Plans bundling a subsidised handset cost more and tie you to a contract term. Prepaid top-ups let you pay only for what you use. Bundling mobile with home internet or TV can reduce the effective monthly price.

Protections and regulation

Mobile services are regulated by AKOS, which oversees consumer rights, number portability, contract transparency and coverage obligations. EU rules guarantee roam-like-at-home pricing across the EU and cap intra-EU call charges. Operators must publish clear terms and allow switching, and complaints can be escalated to the operator and then to AKOS. Prepaid SIM registration follows national identification rules.
