Montenegro isn’t part of the European Union, so EU “roam-like-at-home” rules don’t apply here — a foreign SIM can rack up steep charges the moment it hooks onto a Montenegrin tower. The upside is that local prepaid SIM cards are cheap, sold almost everywhere, and packed with data. This guide walks through everything a visitor or new resident needs: where to buy a SIM, how the three networks compare, exact tariff tables, activation codes, registration rules, roaming, and eSIM alternatives.
Basic Information
Montenegro is served by three mobile network operators (MNOs), all running nationwide 2G/3G/4G networks with expanding 5G:
- Crnogorski Telekom (branded simply “Telekom,” formerly T-Mobile/Monet) — majority-owned by Hrvatski Telekom, itself part of the Deutsche Telekom group.
- One Montenegro — formerly Telenor Montenegro (and ProMonte before that), rebranded to One in March 2022 after Hungary’s 4iG Group acquired the business.
- m:tel Crna Gora — a joint venture between Telekom Srbija and Telekom Srpske, generally considered the strongest performer outside the coastal cities.
All three sell prepaid (“pretplata unaprijed” / prepaid) SIM cards to residents and visitors alike, and all three run generous seasonal “tourist” packages with hundreds of gigabytes of data bundled in for a flat fee — genuinely one of the best data-per-euro deals in Europe.
Availability
Prepaid SIMs are sold nationwide and are not restricted to citizens or residents — any visitor with an ID document or passport can buy one. They’re available at:
- Operator-branded retail stores in every town of any size (Podgorica, Budva, Kotor, Tivat, Bar, Herceg Novi, Nikšić, Cetinje, etc.)
- Kiosks, newsstands, and tobacco shops
- Supermarkets and petrol stations (mainly for top-up vouchers)
- Podgorica Airport (TGD) and Tivat Airport (TIV), from tobacco/newsstand kiosks
- Operator websites and webshops, including online eSIM ordering with delivery in some cases
Where to Buy
| Location type | What you’ll typically find |
|---|---|
| Operator flagship stores | Full SIM registration, all tariffs, device sales, best place for postpaid or complex requests |
| Airport kiosks (TGD, Tivat) | Tourist prepaid SIM/eSIM starter packs, sometimes at a slight markup |
| Town kiosks & newsstands | Tourist SIM starter packs and top-up vouchers |
| Supermarkets/petrol stations | Top-up vouchers, occasionally starter packs |
| Official online shops | eSIM purchase and activation, physical SIM delivery (Telekom ships internationally) |
Buying in a city store is usually simplest if you’re not in a rush, since staff handle the registration paperwork for you. If you want data working the moment you land, an eSIM ordered in advance or an airport kiosk purchase are the fastest routes.
Frequencies
| Generation | Bands used in Montenegro | Notes |
|---|---|---|
| 2G (GSM) | 900 MHz, 1800 MHz | Legacy voice/SMS coverage, being phased down by some operators |
| 3G (UMTS/WCDMA) | 2100 MHz | Increasingly deprecated in favor of 4G/VoLTE |
| 4G (LTE) | 800 MHz (B20), 1800 MHz (B3), 2600 MHz (B7) | Backbone of nationwide mobile broadband; 800 MHz gives rural/indoor reach, 2600 MHz gives urban capacity |
| 5G (NR) | n78 (3.4–3.8 GHz mid-band); low-band n28-class spectrum also allocated | Mid-band n78 licenses run through 2038; live in Podgorica, Budva, Cetinje, and other major towns, expanding along the coast |
Nearly all modern unlocked phones (including any iPhone or Android sold in Europe, the US, or Asia in the last several years) support these bands without issue.
Coverage & Speed
| Operator | Population coverage (4G/LTE) | 5G availability | Independent speed standing |
|---|---|---|---|
| Crnogorski Telekom | Nationwide; widely cited as the broadest coverage in mountainous/rural regions (e.g., Durmitor) | Live in major cities, marketed heavily on tourist plans | Rated the fastest mobile network in Montenegro by Ookla for Q3–Q4 2025, with download speeds roughly 15% ahead of the next operator and more than double the third-place network |
| One Montenegro | Around 98% of the population on 3G/4G | Live in the largest cities | Repeated “Best in Test” wins in independent network-quality testing in prior years; particularly strong along the coast and in cities |
| m:tel | Nationwide, frequently praised for consistency in remote coastal villages and mountain areas away from Telekom’s rural strongholds | Live in Podgorica, Budva, Cetinje, and other cities | Reported lowest average latency (ping) among Montenegrin mobile operators in recent measurement periods |
Independent testing (SpeedGEO, Ookla) over the past year has generally put Telekom ahead on raw average download/upload speed nationally, while all three operators deliver comfortably fast 4G/5G in Podgorica and along the Budva–Kotor–Herceg Novi coastal strip. Expect a noticeable speed drop, though rarely a total signal loss, in Durmitor, Bjelasica, and other high-altitude interior regions.
At a Glance: Operator Comparison
| Feature | Crnogorski Telekom | One Montenegro | m:tel |
|---|---|---|---|
| Former name | T-Mobile / Monet | Telenor (until March 2022) | — (newest of the three) |
| Ownership | Hrvatski Telekom (Deutsche Telekom group) | 4iG (Hungary) | Telekom Srbija / Telekom Srpske |
| Regular prepaid SIM price | ~€5 | ~€10 | ~€10–15 |
| Data-only SIM | ~€9.90 | ~€9.99 | Available via prepaid data add-ons |
| Popular tourist package | 500 GB / 15 days for €15; up to 1 TB or unlimited on higher tiers | 500 GB / 15 days for €15 (7-day and 30-day tiers also sold) | 500 GB / 15 days for €15, often with a first-top-up data bonus |
| Reported network strength | Best in rural/mountain areas, fastest average speeds nationally | Best along the coast and in cities, strong network-quality awards | Best in remote coastal villages and interior regions away from main roads |
| eSIM | Yes, available online with international shipping/activation | Yes | Yes, with online ID + selfie verification |
| Official site | telekom.me | 1.me | mtel.me |
Because the packages are so similar in price and data volume, the practical tie-breaker for most travelers is simply which store or kiosk you happen to pass first — or which operator’s coverage best matches the region you’re visiting (coast vs. mountains).
Biometric User Registration
Under Montenegro’s Law on Electronic Communications, mobile operators must register every subscriber — prepaid and postpaid — without delay. In practice this means:
- You must show a valid ID card or passport when buying any SIM card, in person, at an authorized point of sale.
- Since 2017, all three operators have used an electronic registration application at the point of sale: staff scan or key in your ID details on a handheld device, and the SIM is linked to your identity in the operator’s system in real time.
- Buying a SIM from an unauthorized kiosk without completing this registration (or trying to activate it before registration is finished) can cause the card to be blocked.
- Fingerprint-style biometric enrollment is not a general legal requirement for buying a physical SIM in a Montenegrin store — a photo ID and the retailer’s registration app are sufficient.
- Where biometrics do come into play is online eSIM purchases: at least one operator’s tourist eSIM flow includes an identity-verification step involving a photo of your ID document plus a live selfie for a facial match, similar to standard “e-KYC” checks used by banks and fintechs. This is a vendor-level anti-fraud step for remote sales, not a police or immigration biometric database enrollment, and it typically takes only a couple of minutes.
If you’d rather skip any photo/selfie verification step, buying a physical SIM in a staffed store (where the clerk handles registration using your ID) is the more traditional and paperwork-light route.
Device Registration
Unlike countries such as Turkey, Indonesia, or Uzbekistan, Montenegro does not operate a national IMEI blacklisting/registration scheme for handsets brought in from abroad. You do not need to declare your phone at customs or register its IMEI separately with a regulator to use it with a local SIM.
What Montenegro does require is the SIM registration described above — the SIM (not the phone) is what gets tied to your identity. Any unlocked, network-compatible phone can simply have a Montenegrin SIM inserted and used once that SIM is registered and activated. If you’re bringing a used or refurbished phone, it’s still worth checking with the seller that the IMEI isn’t blacklisted for unrelated reasons (theft, unpaid installment, etc.) in its country of origin, since that block would follow the device internationally — but this isn’t a Montenegro-specific rule.
SIM Card Price
| Operator | Standard voice+data SIM | Data-only SIM | Entry-level tourist SIM |
|---|---|---|---|
| Crnogorski Telekom | ~€5 (incl. starter credit) | ~€9.90 | From ~€10–15 for 500 GB |
| One Montenegro | ~€10 | ~€9.99 | From ~€10 for 500 GB (7-day tier) |
| m:tel | ~€10–15 | Included in data add-on bundles | From ~€10–15 for 500 GB |
Prices at airport kiosks can run slightly higher than in-town stores. All three operators periodically refresh their tourist packages for the summer season (June–September), so exact prices and data caps shift year to year — always confirm the current offer on the operator’s official site or in-store before paying.
Top-Up Methods
All three networks support broadly the same recharge channels:
- Prepaid vouchers (typically €5, €10, €20 denominations) sold at stores, kiosks, supermarkets, and petrol stations
- USSD top-up codes — dial the operator’s recharge short-code, enter the voucher’s PIN, and confirm
- Operator apps (Telekom ME, Moj One, Moj m:tel) — top up by card, view balance, and activate add-ons
- Operator websites — online top-up by international debit/credit card
- Electronic top-up at partner terminals — many retail points, mPOS-equipped shops, and Montenegrin Post Office counters can top up your balance electronically without a physical voucher (offered by m:tel and others)
- Auto-renewal on card add-ons — most data packages can simply be repurchased before the current one expires

| Crnogorski Telekom | *111# or *112# | Send “RACUN” to 1467 (free) | Telekom ME |
| One Montenegro | *147# | Call 14147 (free, automated) | Moj One |
| m:tel | *100# (voice/SMS), *108# (data) | — | Moj m:tel |
All three apps let you check balance, data usage, and validity dates free of charge over Wi-Fi or mobile data, even outside your home network’s normal data allowance in most cases.
Official Websites
- Crnogorski Telekom: telekom.me
- One Montenegro: 1.me
- m:tel Crna Gora: mtel.me
Apps
- Telekom ME — top-up, balance, add-on activation, bill/e-services for Crnogorski Telekom customers (iOS App Store / Google Play)
- Moj One — official self-care app for One Montenegro; top-up, data add-ons, even municipal parking payment (iOS App Store / Google Play)
- Moj m:tel — official m:tel Crna Gora app covering mobile, TV, and internet accounts, balance checks, bill payment, and add-on activation (iOS App Store / Google Play)
How to Check the SIM Number
If you don’t know your new Montenegrin number:
- It’s usually printed on the SIM card’s plastic carrier/packaging at the point of sale — check this first.
- Each operator’s self-care app displays your own number on the home screen once logged in.
- You can call or text a friend, who will see the number on their end, or use the operator’s balance-check USSD menu, which typically displays the subscriber number as part of the response.
- Store staff can also read the number back to you at activation if you registered in person.
Tourist SIM
All three operators run dedicated, no-strings “tourist” SIM/eSIM lines, distinct from their standard consumer prepaid tariffs, aimed squarely at short stays:
- Large flat data allowances (500 GB is the current standard entry tier across the market, with 1 TB or “unlimited” options on longer/pricier tiers)
- Short, fixed validity windows matching typical trip lengths (7, 15, 30, or up to 45 days)
- A working local Montenegrin number for calls/SMS in most packages, useful for restaurant reservations, taxis, or Viber/WhatsApp verification
- Simple activation — insert the SIM (or install the eSIM) and it’s typically ready within minutes, sometimes automatically upon first network connection
- Some tourist tariffs restrict or exclude Western Balkan roaming benefits compared to standard consumer plans, so if you’re island- or country-hopping around the region, check the fine print before buying
Tourist SIMs are sold at the same outlets as regular prepaid SIMs — operator stores, airport kiosks, and many newsstands — and require the same ID-based registration as any other prepaid SIM.
Roaming Data
- Montenegro is not in the EU or EEA, so EU-regulated “roam like at home” price caps do not apply to a Montenegro SIM used elsewhere, or to an EU SIM used inside Montenegro. Bringing an EU roaming SIM into Montenegro can trigger high per-MB charges unless your home operator has a specific Montenegro/Balkans bundle.
- Since July 2021, Montenegro has joined Albania, Bosnia and Herzegovina, Kosovo, North Macedonia, and Serbia in a Western Balkans (WB6) roaming-reduction area, where a Montenegrin SIM can be used in the other five markets without the old, punitive surcharges — though this typically applies only to standard consumer prepaid/postpaid tariffs, not to the discounted tourist SIM lines, some of which explicitly exclude roaming.
- If your trip spans Montenegro plus neighboring Balkan countries, a standard (non-tourist) prepaid plan from any of the three operators is generally the better choice for WB6 roaming coverage.
Digital eSIM Providers
Alongside the three local operators’ own eSIM offers, a wide range of third-party global eSIM brands sell Montenegro-specific or regional data plans that install before you even leave home:
- Airalo — budget-friendly, small-to-medium data packages, good for short trips with light data needs
- Holafly — unlimited-data plans aimed at heavy streamers/hotspot users, priced at a premium
- Saily — prepaid eSIM data plans purchasable and activatable entirely online
- Yesim — data-only eSIM packages for short and longer stays, managed via its own app
- Roafly — data-only eSIMs riding on the m:tel network, with hotspot support and no mandatory identity verification
- MobiMatter, GlobaleSIM, GoMoWorld, eSIMX, Orange Travel, eSIM.dog, and dozens of others aggregated on comparison marketplaces
These third-party eSIMs typically ride on one of the three local networks as a wholesale/roaming partner, so coverage quality mirrors whichever host network they use — worth checking before buying if you’re headed somewhere remote like Durmitor. They trade a small premium (or, in some cases, a lower price than local tourist SIMs) for the convenience of activating before arrival and skipping any in-country registration or ID-check process.
Other Options
- Postpaid contracts — available from all three operators for longer-term residents, but generally require a local registered address and, for foreigners, more paperwork than prepaid.
- Fixed/home broadband + mobile combo — worth considering for digital nomads or remote workers staying more than a month or two, since tourist SIM data caps and validity windows aren’t designed for long-term use.
- Portable Wi-Fi / pocket hotspot rental — an alternative for groups sharing one data connection across multiple devices, though a local SIM with hotspot tethering enabled is usually cheaper.
- Free Wi-Fi — widely available in cafés, hotels, and along the main coastal promenades, useful as a backup but not a substitute for mobile data when moving around.
Activation Help Line Numbers
| Operator | Customer service line | Notes |
|---|---|---|
| Crnogorski Telekom | 1500 (private/individual customers), 1515 (business customers) | Also reachable via the Telekom ME app and social channels |
| One Montenegro | 1700 | English-speaking agents generally available; also via live webchat on 1.me |
| m:tel | 14788 (automated top-up/service line) | General customer service also reachable via mtel.me and the Moj m:tel app |
If a call center agent doesn’t answer in English immediately, ask to be transferred — all three operators have staff trained to assist international visitors, especially during the peak summer season.
Conclusion
Montenegro is one of the friendliest countries in Europe for prepaid mobile data: three competitive operators, near-identical and genuinely generous tourist packages (500 GB for around €10–15 is the current market norm), easy nationwide availability, and straightforward ID-based registration with no mandatory fingerprint biometrics or device IMEI red tape. Crnogorski Telekom currently has the edge on raw speed and rural/mountain coverage, One Montenegro is strongest along the coast and in cities, and m:tel is the value pick for remote areas and travelers island-hopping across the Western Balkans thanks to its WB6 roaming reach. Whichever network you choose, buying a local SIM — physical or eSIM — will almost always beat relying on your home operator’s roaming rates, since Montenegro sits outside the EU’s roaming-fee protections. Compare the current tourist packages on telekom.me, 1.me, and mtel.me before you travel, and you’ll be online within minutes of landing.
Prices, data allowances, and package names are updated seasonally by all three operators (especially for the June–September tourist season) — always confirm current offers on the official websites or in-store before purchase.
