What Si.mobil does
A1 Slovenija d.d., operating under the former name Si.mobil until its rebranding under the A1 Telekom Austria Group, is Slovenia's second-largest mobile network operator and full-stack telecommunications provider, headquartered in Ljubljana. The company operates a 5G mobile network complemented by fiber-to-the-home (A1 Optika / Net maxi) and 5G fixed-wireless access (A1 Ultra Net), alongside the Xplore TV IPTV platform with Smart TV and mobile viewing apps. Its core technology stack includes VoLTE/VoWiFi voice services, eSIM provisioning, multiSIM for smartwatch and tablet sharing of a single number, and the Moj A1 self-service application available across iOS, Android, and Huawei AppGallery.
The business model is anchored in recurring monthly subscriptions across postpaid mobile (MIO, A1 Vajb, A1 miniVajb, Senior MIO, multiMIO multi-line bundles), prepaid (A1 Simpl), and converged fixed internet/TV packages, supplemented by hardware installment sales for Apple, Samsung, Xiaomi, Google Pixel, Huawei, and Honor devices, international roaming services, and add-ons such as A1 Protekt device insurance, A1 Mojster home repair, and bundled streaming content (SkyShowtime, HBO Max, Netflix, Deezer, VOYO). Pricing is subscription-based with monthly billing, with devices financed up to 24 months. The go-to-market is a hybrid direct-to-consumer model combining owned physical retail stores (prodajna mesta), the a1.si e-commerce site, the Moj A1 app, a dedicated business sales team (Poslovni), and marketing partnerships with device OEMs and streaming providers. Customer segments span individual consumers, SMEs, and enterprise accounts, further sub-segmented by age and lifecycle (youth, children, seniors, multi-line households). The company is a wholly-owned subsidiary of A1 Telekom Austria Group, which provides group-level infrastructure, brand, and roaming capabilities across Austria, Croatia, Serbia, Belarus, Bulgaria, and Macedonia.
