Why get a SIM card in Montenegro?

A local SIM card is one of the smartest choices for travelers visiting Montenegro. It keeps you connected without breaking the bank and ensures strong coverage throughout the country. Here’s why it’s worth getting one:

• Enjoy better local coverage: Get reliable signal across Montenegro, from coastal towns to mountain regions.
• Save on data roaming fees: Avoid high fees since there’s no need to activate international roaming services with your home carrier.
• Access affordable data plans: Choose from flexible prepaid options tailored to short- or long-term stays.
• Stay connected easily: Use maps, translation apps, and messaging services without depending on Wi-Fi.
• Get local rates for calls and texts: Communicate with local businesses or accommodations at lower costs.

How to purchase and activate a SIM card in Montenegro?

Buying a SIM card in Montenegro is easy, and you can do it either in person or online, depending on what’s more convenient for you.

You can purchase a Montenegro SIM card from:

• Airports: Available at Podgorica and Tivat Airports near the arrivals area.
• Official stores: Visit Telekom or One Montenegro retail shops in major cities.
• Supermarkets and kiosks: Commonly sold at Voli, Idea, and local convenience stores.
• Online stores: Both providers let you order physical SIM cards online through their official websites. You can pick them up in-store or have them delivered to your local address once you arrive.

To activate your Montenegro SIM card:

• Insert the SIM into your unlocked phone.
• Turn on your device and keep in mind that activation usually starts automatically.
• Follow any on-screen prompts or SMS instructions to confirm activation.
• If required, register your SIM with a valid ID at a store or online portal.

Montenegro SIM card activation requires purchasing and setting up your SIM after arrival. Make sure your phone is carrier-unlocked and bring a valid ID, such as your passport, as both are required for registration.

To save time and skip queues, you can also buy and activate a SIM card online before your trip so it’s ready to use when you land. Alternatively, you can get an eSIM to stay connected instantly as soon as you arrive in Montenegro.
