The roaming trap
Montenegro sits outside the EU's roam-like-at-home area. Some European operators include it voluntarily in a wider zone; many do not, and charge per megabyte. Check before you land rather than after, because the bill arrives a month later when it is too late to do anything.
The three operators
| Operator | Tourist package | Strength |
|---|---|---|
| Telekom (Crnogorski Telekom) | €10 – €15 for 20–50 GB | Best coverage in the north and the canyons |
| One (formerly Telenor) | €10 – €15, similar data | Strong on the coast, good in cities |
| Mtel | €8 – €12 | Cheapest, thinner rural coverage |
If your trip stays on the coast, any of them is fine and the cheapest wins. If you are going to Durmitor, the Tara or Prokletije, take Telekom. The difference in the mountains is not marginal.
Where to buy one
- Airport kiosks at Podgorica and Tivat — most expensive, but open when you land.
- Operator shops in any town — best prices, need your passport, takes ten minutes.
- Petrol stations and kiosks sell top-up vouchers but usually not new SIMs.
Registration requires a passport. This is a legal requirement, not an upsell.
Where there is no signal at all
This matters more than the price, because people plan around having a phone and then do not have one.
- Inside the Tara canyon, on the water, between the put-in and Šćepan Polje. Nothing, all operators, for hours.
- Nevidio canyon — nothing, and you are in a slot with vertical walls.
- The Piva canyon road tunnels — intermittent, which matters if you break down in one.
- High Durmitor above the treeline — patchy, better on ridges than in valleys.
- Parts of Prokletije near the Albanian border, where the phone may hop onto an Albanian network and start roaming without telling you.
That last one is worth guarding against: turn off automatic network selection near the southern and eastern borders, or you can be roaming on a foreign network while standing in Montenegro.
Download the map before you go north
Offline maps of the whole country are a few hundred megabytes and solve most of the problem. So does telling somebody your plan for the day. In the canyon the guide has a satellite phone or a radio; you have neither, and that is fine as long as you are not relying on yours.
