Mobile networks in Croatia

Computatus eSIM plans for Croatia connect to local networks: A1, Tele2 and T-Mobile. Your phone picks the strongest signal among those the plan lists.

Setting it up

  1. Check your phone. It must support eSIM and be unlocked. On an iPhone, Settings > Mobile Data shows Add eSIM; on Android, look under SIM or Network settings.

  2. Install before you fly. Open the link or scan the QR code from the email while you still have Wi-Fi at home. The plan's days start when it first connects abroad.

  3. Switch data on arrival. Set the eSIM as your line for mobile data and turn its data roaming on. Leave your UK SIM on for calls and texts.

  4. Coming home. Switch mobile data back to your UK SIM. You can delete the travel eSIM once its plan has ended.

How to keep your UK number abroad

Croatia eSIM: questions

Which eSIM plan do I need for a week in Croatia?

For a week of maps, messages, social media and some video, about 5 GB is enough: 5GB · 30 days costs US$4.43 (about £3.33).

Which networks does a travel eSIM use in Croatia?

Computatus eSIM plans for Croatia use A1, Tele2 and T-Mobile.

Is there 5G in Croatia?

Yes: plans list 5G on A1, Tele2 and T-Mobile. On a phone without 5G the same plans work on 4G.

Can I keep my UK number while I use an eSIM?

Yes. Most phones hold your UK SIM and an eSIM at once: keep the UK SIM on for calls and texts, including your bank's security codes, and use the eSIM for data.

When should I buy and install the eSIM?

Before you travel, while you have Wi-Fi at home: installing takes a few minutes, and the plan's days only start when it first connects in Croatia.
