Kvarner eSIM plans: unlimited, or by the GB.
Every Kvarner eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Kvarner — you can always top up or switch on your next trip.
Unlimited plansHigh-speed data, nothing to count
Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.
- Best for streaming, video calls & hotspot
- Great for longer or open-ended trips
- One price per day — no GB anxiety
A set bundle, brilliant value
A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
- Best value for lighter, shorter trips
- Clear allowance — pay only for what you need
- Top up any time from your phone
How much data do you need in Kvarner?
A rough, honest guide to sizing your Kvarner eSIM so you're not guessing. Most travellers in Kvarner are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.
Everything above plus social scrolling, music, cloud photo backups and a little video. Where most travellers land.
Netflix by the pool, long video calls home and hotspot for the laptop — go Unlimited and stop counting.
Kvarner eSIM: your local data guide.
The Kvarner Gulf mixes the port city of Rijeka, belle-époque Opatija and a scatter of big islands, and a Kvarner eSIM keeps you online across all of it. You'll want data for the Krk bridge drive, ferry times to Cres and Lošinj, and coastal walks along the Opatija Lungomare.
Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
Where you'll lean on data in Kvarner.
Opatija's seafront Lungomare and grand hotels enjoy strong, steady 4G and 5G along the whole promenade.
Rijeka, Croatia's main port city, carries reliable high-speed data across its centre and the Korzo.
On Krk, reached by bridge, signal is solid in Krk town and Baška but softer across the island's rocky interior.
Around Mali Lošinj coverage is good in town, thinning on the quieter coves and the Cres-Lošinj hinterland.
Getting around Kvarner on your eSIM.
- Autotrolej— Rijeka and Opatija's public bus network, useful for getting around the Kvarner coast.
- Jadrolinija— Ferries to and between the Kvarner islands of Cres, Rab, Krk and Lošinj.
- Bolt— Ride-hailing available in Rijeka and the surrounding coastal towns.
- FlixBus— Long-distance coaches linking Rijeka with Zagreb, Zadar and Istria.
Many spend three to five days in Kvarner, combining Opatija or Rijeka with an island stay on Krk, Rab or Lošinj.
A balanced 3-5 GB covers a typical Kvarner visit of maps, ferry apps and photos; opt for Unlimited if you plan to stream or tether from your island base.
Opatija, Rijeka and the main island towns enjoy strong 4G and 5G, but coverage realistically thins across the rocky interiors of Krk, Cres and Lošinj and on quieter island roads.
