Kotor visitors need mobile data for transfers, maps and accommodation messages, but stone buildings, bay terrain and mountain roads can affect signal locally.
A Montenegro eSIM, local SIM or home roaming can provide the connection.
NoveSIM plans are data-only and do not include a Montenegrin number, conventional calls or SMS.
Quick answer: Use an eSIM for immediate data, a local SIM if you need a Montenegrin number, and roaming only after checking the home-carrier price. Save the old-town address and bay route offline.
