Montenegro SIM Card for Tourists: One, Telekom and m:tel Prices, Passport Rule and EU Roaming

Last updated on 30 October 2026

A tourist SIM in Montenegro costs €15 for 500 GB over 15 days at Crnogorski Telekom and at One, with 9 to 10 GB for the other Western Balkan countries included, and you register it with your passport or EU ID card. The POVNOMAD Montenegro eSIM starts at €3.90 for 1 GB over 7 days and €12.90 for 10 GB over 30 days, with no Montenegrin registration. Montenegro uses the euro but is outside EU roaming. As of 29 October 2026.

The honest line runs at about 10 GB. Below it, our eSIM costs less than any local tourist pack, because the smallest pack costs €15. Above it, or once you want unlimited data for two weeks or a month, the local SIM wins: €15 for 500 GB against €35.90 for 15 days of our Unlimited XL. This guide shows the packs of all three operators, the registration rule and what your home contract charges.

Local SIM, travel eSIM or roaming: what is the difference in Montenegro?

As of 29 October 2026. Operator prices from telekom.me, 1.me and mtel.me, POVNOMAD prices from the Montenegro product page, all read that day. Montenegro uses the euro, so no exchange rate applies. o2 zone from o2online.de (29 October 2026), price per MB as reported by teltarif.de in August 2026.

What do the tourist SIMs of One, Crnogorski Telekom and m:tel include?

All three operators sell tourist packs with a fixed price and a large data allowance for Montenegro, plus a smaller allowance for roaming in the Western Balkans. Telekom and One also sell them as eSIMs on their websites.

Sources: telekom.me, tourist offer, 1.me, One Turist and mtel.me, for tourists, all retrieved 29 October 2026. “Western Balkans” means Albania, Bosnia and Herzegovina, Kosovo, North Macedonia and Serbia. m:tel names the cards Turist 15 and Turist 20 but gives no price in the text, so we quote none.

Two details matter for planning. Your first top-up adds data: One adds 500 GB for a top-up of €4 or more, Telekom adds 500 GB plus 3 GB of regional data for 5 days, m:tel adds 500 GB. And when the pack runs out, m:tel cuts the data connection until you top up or book a new offer via *105#, for example 500 GB for 7 days at €10. One sells add-ons via *140#, from 1 GB for one day at €1.99.

Which is cheaper for your trip?

Compared with travel eSIMs bought before departure, as of 29 October 2026:

All prices retrieved 29 October 2026 from telekom.me, 1.me, povnomad.com, airalo.com and esim.holafly.com/de, in euros. POVNOMAD Unlimited XL gives 3 GB of high-speed data per 24 hours, then 1 Mbit/s without a hard stop. Airalo sells Montenegro under the brand “Jezero”. Validity of the eSIMs starts on first contact with the network in Montenegro.

Why does my home plan charge roaming in Montenegro?

Because Montenegro is not part of the EU roaming area, even though it borders Croatia and pays in euros. Your domestic allowance stops at the border south of Dubrovnik. With a German contract, o2 puts Montenegro in world zone 3, where teltarif.de reported €0.99 per MB without an add-on (August 2026), and stops data at the €59.50 cost cap. Vodafone charges about €0.12 per MB in its zone 5, and Telekom allows data only with a pass. The full table for German carriers is in roaming outside the EU.

EU roaming for the region is announced, not agreed. The Council of the EU authorised negotiations with the six Western Balkan countries on 4 June 2026 (European Western Balkans). As of 29 October 2026, no agreement is in force and no start date is set.

Near the border your phone can also join a Montenegrin network while you are still in Croatia. How to stop that is in our guide to border roaming in the Balkans.

Do you need a passport to buy a SIM card in Montenegro?

Yes, or an ID card if you come from the EU or the Balkans. Crnogorski Telekom states that the law requires every mobile SIM card to be registered with an ID card or passport; citizens of other countries must show a passport. If you buy Telekom’s eSIM online, you complete a biometric identification online, which Telekom says takes no longer than two minutes. One asks you to register the number when you buy its eSIM online.

A travel eSIM like ours roams on a Montenegrin network and needs no Montenegrin registration.

Does a Montenegrin SIM work in Albania, Bosnia, Serbia or Croatia?

In the Western Balkans, yes. Since 1 July 2021, Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have had roam like at home among themselves (Regional Cooperation Council). The tourist packs set a separate regional allowance for this: 9 to 15 GB at Telekom, 10 to 20 GB at One, 9.92 to 20 GB at m:tel.

Croatia is outside that agreement. Of the packs above, only Crnogorski Telekom includes Croatia in its regional allowance, which helps on a day in Dubrovnik. Our Montenegro eSIM works in Montenegro only. For a route through several countries, the Montenegro and Albania trip guide and the Balkan eSIM comparison show which plan covers which country.

Which network does the POVNOMAD eSIM use?

Montenegro has three operators: Crnogorski Telekom, One and m:tel. Our product page names m:tel as an example of the local 4G network the eSIM connects to; the networks actually used appear after purchase in the POVNOMAD app. All three operators advertise 5G. We found no independent measurement per operator for 2026, so we do not rank them.

How to buy the local SIM the right way

1. Check that your phone is unlocked. A phone locked to your home operator rejects a Montenegrin card.
2. For an eSIM from Telekom or One, buy on telekom.me or 1.me before you travel and keep your passport at hand for the online identification.
3. For a physical card, go to an operator shop or a marked point of sale and bring your passport or EU ID card.
4. Pick the pack by days, not by gigabytes: 500 GB lasts any normal holiday. Check that the regional allowance covers the countries you cross.
5. Top up once early if you want the bonus: One needs €4 or more, Telekom’s top-ups start at €4 online and €5 at points of sale.
6. With one physical slot and a physical home SIM, the Montenegrin card replaces it, and your home number goes offline until you swap back.

When the eSIM is the better choice, and when not

The eSIM is worth it when you need little data or few days:

• Day trips and short stays. A day in Kotor from Dubrovnik costs €3.90 with 1 GB over 7 days, against €15 for the smallest local pack.
• Up to about 10 GB. 3 GB over 15 days cost €5.90, 10 GB over 30 days €12.90.
• No identification. You skip the passport check and the biometric selfie.
• Your home SIM stays in the phone for calls and bank codes, while the eSIM carries the data. Installation steps are in our guide for iPhone and Android.

The local SIM is the better choice from about 10 GB, for unlimited data over two weeks or a month, when you need a +382 number, and when you cross into Albania, Bosnia, Serbia or Croatia with the same card. For 15 days of unlimited use you pay €15 locally and €35.90 with us. Prices for POVNOMAD against Airalo and Holafly are in the Montenegro eSIM provider comparison. Montenegro pays in euros; what cash withdrawals cost there is in ATM fees in Montenegro. This guide is also available in German.
