Verifying against the live site and live WHOIS/DNS…
Common questions
Is t-mobile.at legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns t-mobile.at?
Nobody has completed AboutUs's owner verification for t-mobile.at. That's true of most sites here — it isn't itself a warning sign.

The live front page reads as a business-services site that sells its own services, mainly for the public as customers.
We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
Retained threat-feed result (recorded about 1 days ago); name-similarity check available (recorded about 1 days ago); 3/3 transport and email checks available (oldest recorded about 1 days ago). This is evidence coverage, not a probability that a website is safe.
No caution flags in the available scoring observations; this is not a complete safety assessment
