A1 Hrvatska and travel eSIM in Croatia

A1 Hrvatska in brief

A1 Hrvatska switched off its 3G network across Croatia on 6 July 2026, so phones now need 4G/LTE or 5G to connect.

A1 Hrvatska's bands and technology

An eSIM can only use A1 Hrvatska if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.

A1 Hrvatska's coverage map

A1 Hrvatska publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows A1 Hrvatska's own network; a roaming plan may not get every technology it shows.

Who licenses A1 Hrvatska

Mobile networks in Croatia are licensed, and their spectrum assigned, by the Croatian Regulatory Authority for Network Industries (HAKOM). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.

The plans on our shelf that name A1 Hrvatska

From the supplier record behind each package, 100 of the 100 plans we currently sell for Croatia declare A1 Hrvatska as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.

Why plans do not name a fixed network

Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If A1 Hrvatska is weak where you are, try selecting Hrvatski Telekom or Telemach Hrvatska manually in the network settings, and keep data roaming on for the eSIM profile.
