Korčula Connectivity Snapshot

Providers
Hrvatski Telekom (HT), A1, and Telemach are the main operators. HT often provides the most consistent coverage.
Towns vs. Rural
Korčula Town and Vela Luka boast solid 4G/LTE, even some limited 5G. Venture outside these hubs, and signal strength plummets rapidly.
Data Speeds
In covered areas, speeds are sufficient for streaming, video calls, and general browsing.
Remote Spots
Expect dead zones in isolated coves, mountainous interior, and while island hopping on smaller ferries. Network marketing makes island coverage seem flawless; it isn't.
Recommendation
Purchase a local prepaid SIM card or eSIM (HT or A1 recommended) upon arrival for best rates and reliability. Check specific coverage maps before committing.
