A1 Hrvatska D.O.O.

A1 HRVATSKA D.O.O. appears in public materials as a Croatian telecommunications operator and a member of the A1 Telekom Austria Group. Public documents list its Zagreb address and corporate contact points, and it is also shown in RIPE NCC membership listings for Croatia.

Multiple public ASN directories map A1 Hrvatska d.o.o. to AS25528 and also show other ASNs associated with the brand (for example AS15994 and AS31012). PeeringDB lists the network with a Zagreb presence, indicating active interconnection/peering entries rather than a purely reseller footprint.

Online customer feedback is mixed-to-negative overall: Trustpilot contains recurring complaints about support, billing, and service handling, and similar themes appear in Croatian forums/Reddit threads. The volume of criticism is high enough that the public sentiment skews below average.
