FACT · AUSTRIAN MOBILE NETWORK OPERATOR
A1 (Austria)
Updated May 14, 2026 · By Jules de Bruin · Austria's largest mobile network operator, with the best rural and alpine coverage.
Updated May 2026. A1 Telekom Austria is the country's largest mobile network operator, holding a 36.2% retail mobile share per Q2 2025 RTR Telekom-Monitor data and serving roughly 4.96 million consumer SIMs. Independent Opensignal testing rates A1 at 8.4/10 coverage, the highest of the three Austrian MNOs, with the strongest signal across the Alps, Burgenland and rural Lower Austria. A1 also hosts the discount sub-brands bob and yesss!, and is majority-owned by América Móvil through Telekom Austria Group.
What is A1 Austria?
Austria's incumbent mobile operator · widest rural footprint · backbone for several MVNOs
A1 Telekom Austria AG is the country's incumbent mobile and fixed-line operator, headquartered in Vienna and trading under the A1 brand since 2010. It runs its own 2G, 4G LTE and 5G radio network covering roughly 98% of the Austrian population, and it is the only Austrian operator with consistently strong coverage in remote Alpine valleys.
A1 traces its mobile operations back to mobilkom austria, launched in 1996 by the then state-owned PTA group. The company rebranded to A1 in 2010, and today it is part of Telekom Austria Group, which Mexican holding company América Móvil controls with a roughly 51% stake. The Austrian state, via ÖBAG, retains a strategic minority position. The same group operates A1-branded networks in several CEE markets (Slovenia, Croatia, Bulgaria, Belarus, Serbia, Macedonia), but the Austrian unit is the largest and the original.
Inside Austria, A1 sits at the top of a three-MNO market alongside Magenta Telekom and Drei (3 Austria). RTR's Telekom-Monitor consistently shows A1 in first place on retail mobile subscribers, with around 36.2% market share in Q2 2025 and approximately 4.96 million consumer SIMs in service. The operator publishes a 5G footprint reaching more than 90% of the population, alongside the densest 4G site grid in the country.
For end users, A1 sells the full stack: postpaid mobile tariffs (the A1 Allnet family), prepaid (A1 Free), fibre and DSL broadband under A1 Net & Phone, IPTV through A1 Xplore TV, and converged household bundles. Wholesale customers buy capacity for MVNOs, fixed-wireless resellers and enterprise SD-WAN. The brand promise leans on coverage rather than price: in Austrian retail surveys it is the operator most associated with the words "Empfang" (reception) and "Netzqualität".

Which MVNOs run on the A1 network?
Two in-house discount brands · two independent MVNOs partly hosted on A1
The A1 radio network underpins two in-house discount brands — bob and yesss! — and is also used wholesale by independent MVNOs spusu (partial, primarily on Drei) and educom. For Austrian buyers, picking any of these brands means the SIM ultimately rides A1's towers.
- bob. A1's online-first discount brand. Lean tariff line-up, no shops, sold direct at bob.at. Uses A1's full 4G/5G footprint.
- yesss! A1's supermarket discount brand, distributed through Hofer and BILLA, competing head-on with Magenta's HoT. Same coverage as A1 retail.
- spusu. Independent MVNO owned by Mass Response Service GmbH. Historically a Drei wholesale customer; some traffic routes via A1 sites in specific regions. Confirm host before buying.
- educom. Niche MVNO targeting education sector and B2B; runs partly on A1 wholesale capacity.
All three Austrian MNOs — A1, Magenta and Drei — participate in the same regulatory regime. ID-linked SIM registration is mandatory regardless of which brand you buy: under the 2019 amendment to the Telekommunikationsgesetz, RTR requires every prepaid SIM to be tied to a verified identity document. The host network does not change that obligation.
Where does A1 appear on SimCompare365?

Frequently Asked Questions
Who owns A1 Austria?
A1 Telekom Austria AG is a subsidiary of Telekom Austria Group (Telekom Austria AG). Mexican holding company América Móvil — controlled by the Slim family — owns the majority stake of around 51%, while the Austrian state holding ÖBAG retains roughly 28% under a syndicate agreement.
Is A1 the best network in Austria?
On coverage A1 leads independent measurements: Opensignal scores it 8.4/10, the highest of the three Austrian MNOs, especially in Alpine and rural regions. Magenta is competitive on speed inside Vienna and major cities, and Drei often wins on price-per-GB. For population reach and rural reliability, A1 is the benchmark.
What is the difference between A1, bob and yesss!?
All three SIMs ride the same A1 radio towers, so coverage is identical. A1 is the premium retail brand sold in A1 Shops with full-service support. bob is an online-only discount sub-brand. yesss! is the supermarket discount brand sold via Hofer and BILLA. Cheaper brands typically offer fewer included services (no roaming inclusions, no shop support) in exchange for lower tariffs.
Does A1 include EU roaming?
Yes. As an EU operator A1 applies Roam Like at Home (RLAH) across the EU-27 plus Iceland, Liechtenstein and Norway on all standard consumer tariffs, subject to fair-use volumes. Switzerland and the UK are not in the EU roaming zone, so they are billed separately unless the specific tariff opts them in.
Do you need ID to buy an A1 SIM?
Yes. Since the 2019 amendment to the Austrian Telekommunikationsgesetz, every prepaid and postpaid SIM must be registered against a verified identity document — passport or EU national ID card. RTR enforces the rule, and it applies equally to A1, bob, yesss! and all other Austrian SIMs.
