FACT · AUSTRIAN MOBILE NETWORK OPERATOR
Magenta Telekom
Updated May 14, 2026 · By Jules de Bruin · Austria's second-largest MNO and the urban speed leader.
Updated May 2026. Magenta Telekom is Austria's second-largest mobile network operator and the local arm of Deutsche Telekom AG. It runs its own 4G/5G radio network, holds roughly 24.9% of consumer SIMs (Q2 2025 RTR), and is the urban speed leader at 187.51 Mbps (Opensignal). Magenta is strongest in Vienna and other major cities, sells the Magenta One mobile + fibre + TV household bundle, and hosts MVNOs HoT (sold at Hofer) and ay yildiz Austria.
What is Magenta Telekom Austria?
Magenta Telekom is the Austrian operating company of Deutsche Telekom AG. It runs one of Austria's three nationwide 4G/5G mobile networks, sells mobile contracts and prepaid SIMs under the Magenta brand, and operates the country's largest cable and fibre broadband footprint inherited from UPC Austria. Headquartered in Vienna, it is regulated by RTR and supervisory authority KommAustria.
Magenta's lineage runs through max.mobil (launched 1998), T-Mobile Austria (2002 rebrand after the Deutsche Telekom acquisition), and finally Magenta Telekom in 2019 — a renaming that aligned the Austrian unit with the group's magenta corporate identity and merged the mobile business with UPC Austria's cable and TV assets. Magenta is now the only Austrian operator that owns both a nationwide mobile radio network and a nationwide hybrid fibre-coax (HFC) and fibre-to-the-home (FTTH) fixed-line footprint, which is why the household bundle is its strategic anchor product.
In numbers, Magenta sits behind A1 Telekom Austria and ahead of Drei (Hutchison Drei Austria) on consumer market share. RTR's Q2 2025 Telekom-Monitor reports Magenta at roughly 24.9% of active consumer SIMs (around 3.42 million). On network quality, Opensignal's most recent Austria report scored Magenta first for overall download speed at 187.51 Mbps, with the gap most pronounced in urban 5G cells in Vienna, Graz, Linz, Salzburg, and Innsbruck. Outside those metropolitan areas — especially in alpine valleys and rural Lower Austria — A1 remains the depth leader.

What is Magenta One (mobile + fibre + TV bundle)?
Magenta One is Magenta Telekom's household convergence bundle. It combines a mobile contract, a fixed broadband line (fibre or cable), and Magenta TV under a single monthly invoice, with a discount applied as long as all three services stay active on the same address. It is the only true triple-play offered by an Austrian MNO that owns its own fixed network end-to-end.
Functionally, Magenta One is structured as a primary fixed-line contract (Internet + TV) with a bundle discount applied to one or more mobile SIMs on the same household account. Customers add tariffs from the standard Magenta Mobil range — ranging from entry-level voice + data lines up to the unlimited 5G "Mobil Max" tier — and receive a monthly credit per linked SIM. Magenta TV ships with a streaming app and an optional set-top box, and includes Austrian free-to-air channels, regional broadcasters, and a Sky Sport add-on path.
The bundle leans on Magenta's fixed-line footprint, which is Austria's largest non-A1 broadband network. Magenta sells over hybrid fibre-coax (the legacy UPC cable plant in Vienna, Graz, Klagenfurt, Innsbruck, and other urban areas) and, increasingly, FTTH where the company has built or co-built fibre. In areas Magenta cannot reach directly, the bundle is still available as a mobile-only or as a fixed-wireless "5G Internet" replacement product.
- Who it fits. Households in Vienna and other major cities where Magenta already runs the cable or fibre line — the bundle discount is meaningful when the family has 2+ mobile SIMs plus a TV box.
- Who it doesn't. Single users in rural alpine areas where A1 fibre or DSL is the only practical fixed line. In that footprint A1's equivalent bundle wins by default.
- Commitment. Magenta One typically runs on a 24-month minimum term with a one-off activation fee; promotional pricing applies for the first 6–12 months.

Frequently Asked Questions
Who owns Magenta Telekom?expand_more
Magenta Telekom is a wholly-owned subsidiary of Deutsche Telekom AG, the Bonn-headquartered group that also owns Telekom Deutschland in Germany and T-Mobile US. The Austrian entity operates under Austrian company law and is regulated locally by RTR, but its corporate parent and brand system sit with the Deutsche Telekom group.
Is Magenta the same as T-Mobile Austria?expand_more
Yes — it is the same legal operator with a different consumer brand. The company traded as T-Mobile Austria from 2002 until 2019, when Deutsche Telekom merged it with UPC Austria and rebranded the combined business as Magenta Telekom. Older SIM cards, contracts, and phone numbers carried over unchanged.
How good is Magenta's coverage outside Vienna?expand_more
Magenta is competitive in all major Austrian cities and along the main motorway and rail corridors, and Opensignal ranks it first for download speed. In alpine valleys and rural districts, however, A1 still has the deepest 4G/5G footprint. If you spend most of your time in or between Vienna, Graz, Linz, Salzburg, and Innsbruck, Magenta is a strong choice; for hut-to-hut hiking or remote Tyrol, A1 is typically safer.
Which MVNOs use the Magenta network?expand_more
The two main consumer-facing MVNOs hosted on Magenta are HoT (Hofer Telekom, sold inside Hofer supermarkets — Austria's Aldi) and ay yildiz Austria, a brand aimed at the Turkish-Austrian community. Both ride on Magenta's 4G and 5G radio access but are billed and supported under their own brands.
Do you need ID to buy a Magenta SIM?expand_more
Yes. Since 2019 Austria has required SIM registration for both prepaid and contract lines — a rule enforced by RTR. To activate a Magenta SIM you need to present a valid passport or EU national ID; for contract tariffs you typically also need an Austrian address and bank account.
