Yes, Giga.Tel provides unlimited data eSIM plans that cover Croatia. The plans give unlimited high‑speed data with a maximum speed of 10 Mbps on a 5G network, and they allow tethering. Validity periods range from 1 day to 30 days, and the prices vary from about $3.15 for a one‑day plan to roughly $60.75 for a 30‑day plan.
Because the plans are subject to a Fair Usage Policy, speeds may be throttled after heavy use. If you need confirmation of the exact throttling limits or the typical amount of data that can be used at normal speed, contact Giga.Tel directly.
