The shape of a Croatia trip is either a week on a boat or eight hours in a port
A summer in Croatia comes in two formats. Format one: a week on a yacht charter or a long stay on Hvar, Brač, or Vis. Format two: a Mediterranean cruise that drops you in Dubrovnik or Split for the day before sailing on to Italy. The needs differ, but both want a tariff that turns on by itself and bills by what you actually used.
Free hotel Wi-Fi at the resort is one of the most expensive things in the brochure — not because they bill you for it, but because of what it doesn't include. Coverage skews to the lobby and pool bar; rooms and the beach are weaker or none.
If you came on a cruise, ship Wi-Fi runs $25/day, and the moment you walk down the gangway in Dubrovnik or Split you're in a foreign country with no plan. A home phone in roaming bills more than the day cost on the ship.
What does Roamzy cost for a short stay?
Roamzy charges $1.43 per gigabyte in Croatia. That's $0.0014 per megabyte, real-time billing, balance carries, no expiry. One per-MB rate across 192 countries — the shape of the invoice, not a marketing line.
A typical visitor uses about 1 GB/day: Maps from the cruise gangway up to Stradun, the camera-translator on a konoba menu, WhatsApp to confirm the Pakleni Islands boat, contactless payments, the occasional video call. Resort and ship Wi-Fi handle some of it. Call it 1 GB/day for the math:
| Trip length | Roamzy ($1.43/GB) | Tourist roaming pass | Cruise-ship Wi-Fi |
|---|---|---|---|
| 1-day port stop | $1.43 | — | $20–35 |
| 5 days (short stay) | $7.17 | $30–80 | — |
| 10 days | $14.34 | $60–130 | — |
| 2 weeks | $20.07 | $80–160 (often two passes) | — |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier, your hotel, and your cruise line. Roamzy's rate in column 2 is our actual published rate from the pricing page.
An airport SIM at SPU, DBV, or ZAG runs $10–25 plus passport and 20 minutes in line after a long flight. On a cruise stop, you don't physically have the time — the ship leaves at 17:00. The eSIM is already attached before you walk down the gangway.
What does 'free Wi-Fi' fail to cover?
Coastal hotels and yacht charters all do put "free wifi" in the brochure honestly, but in practice:
- Coverage skews to the lobby and pool bar — your room and the beach are weaker
- Often a daily time cap or speed throttle once you hit it
- Streaming is often blocked on cruise-ship plans — the pipe to a 3,000-cabin ship isn't infinite
- Video calls go through but quality bounces in port and offshore
Your own connectivity isn't "instead of" hotel or ship Wi-Fi — it's "for when the Wi-Fi doesn't reach." On the boat between Hvar and Vis. On the city walls in Dubrovnik when the navigator's lost. At a small konoba on Korčula when your bank app wants to confirm the charge.
Where does Roamzy work in this country?
| Region | 4G/5G | Reality |
|---|---|---|
| Dubrovnik (incl. cruise port) | 4G/5G | Solid in Old Town and along the Stradun |
| Split (incl. cruise port) | 4G/5G | Strong across Diocletian's Palace and the Riva |
| Hvar, Brač, Korčula, Vis | 4G | Solid in towns; coves and far beaches drop |
| Zagreb, Zadar, Rijeka | 5G | Strong in cities and along the Adriatic Highway |
| Plitvice, Krka, Mljet | 4G | Visitor centers OK; trail interiors patchy |
| Yacht routes between islands | 4G | Near coast OK; mid-channel drops briefly |
How do I install my Roamzy eSIM?

What are Roamzy's honest limitations?
Resort and cruise travelers historically lose money to three things, and Roamzy doesn't close those traps — they don't exist in the product.
- No welcome promo that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling that surfaces on the cruise day. One rate, full speed — first GB and the hundredth cost the same $0.0014/MB.
- No auto-renewal you forgot to cancel before flying home. Balance runs out, the eSIM stops.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if my trip continues to other countries?
Croatia is rarely the only stop on a Mediterranean itinerary:
- Italy — common next cruise call across the Adriatic
- Greece — frequent extension by air or longer Mediterranean cruise
- Austria — by car from Zagreb or Rijeka, separate country rate
- If you want the underlying mechanics — how roaming actually gets priced and why it hurts
