Power & Connectivity (SIM)

Montenegro uses 230V / 50Hz with Type C and Type F sockets (European two round pins). Bring a Type C/F adapter; travellers from 100–120V countries need a converter for devices that are not dual-voltage.

The main operators are Crnogorski Telekom, m:tel and One (formerly Telenor), with good 4G and growing 5G. Prepaid SIMs are sold at the airport, operator shops and kiosks; bring your passport, as registration is required. Montenegro is outside the EU, so EU roaming rules do not apply and roaming can be costly.

International travel eSIMs such as Airalo work well in Montenegro: buy one online before arrival and install it in minutes, with no physical SIM or shop visit. Since Montenegro is outside the EU, an eSIM is often cheaper than home roaming.

Wi-Fi is widely available in hotels, cafés and restaurants, and is generally good in towns and along the coast. In remote mountain areas connections can be slower. Use a VPN on public networks for sensitive tasks like banking.

Montenegro has an open internet with no significant restrictions. All standard apps and services — messaging, social media, maps and streaming — work normally.

Handy apps include WhatsApp and Viber for messaging and calls, Google Maps for navigation, and translation apps. International ride-hailing like Uber is largely unavailable, so use local taxi apps or phone dispatch instead. Cash is still common, though cards are accepted in cities.

Montenegro's country code is +382. The single emergency number is 112, with 122 for police, 123 for fire and 124 for the ambulance. App-based calls (WhatsApp, Viber) are common. Save numbers in full +382 format so they work from any network.
