Looking for the best eSIM for Montenegro? Most trips start at Tivat or Podgorica airport, or over the border from Dubrovnik, and take in the Bay of Kotor, Budva's old town, Sveti Stefan and the Durmitor mountains.

We checked prices on 4 November 2026 across ONE eSIM, Airalo, Holafly, Saily and Nomad, so you can compare every size side by side.

Holafly sells only unlimited plans for Montenegro, so it has no price in the GB rows; its 7-day plan is in the week table below.
A week of unlimited data in Montenegro
| Provider | 7 days | What you get |
|---|---|---|
| ONE eSIM | $18.48 | 1 GB a day at full speed, then 512 Kbps until the next day (7 × $2.64) |
| Airalo | $33.50 | 3 GB a day at full speed, then 1 Mbps (fair use) |
| Holafly | $33.90 | No daily cap; fair use may slow very heavy use |
| Saily | $35.99 | 3 GB a day at full speed, then up to 1 Mbps |
| Nomad | $23.00 | 2 GB a day at full speed, then 1 Mbps |
For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $18.48. The cheapest of the others is Nomad at $23.00, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.
Networks and coverage in Montenegro
ONE eSIM's Montenegro plans run on m:tel and T-Mobile, both with 5G where available (your phone may show the operator's current brand name instead). Kotor, Budva, Tivat, Herceg Novi and Podgorica are well covered; the canyon roads and Durmitor National Park have gaps on every network, so save offline maps first.
Which eSIM should you choose for Montenegro?
- Short trip, light use (up to 3 GB): ONE eSIM's 3 GB plan at $6.33 (15 days), the cheapest at that size.

- Heavy use (20 GB): Nomad at $25.00 (30 days) is the cheapest at 20 GB.
- Streaming or video calls every day: compare the unlimited plans above by how much full-speed data each gives a day.
How to set up your Montenegro eSIM
- Check your phone supports eSIM and is carrier-unlocked.
- Install the eSIM on Wi-Fi before you fly or cross the border, so it is ready when you arrive.
- In Montenegro, turn on the eSIM line and data roaming for it, choose it for mobile data, and keep your home SIM's data roaming off to avoid charges.
Montenegro eSIM FAQ
- Does EU roaming work in Montenegro? No. Montenegro uses the euro but is not in the EU, so "roam like at home" does not apply; check your home plan's rates, or use a travel eSIM for data.
- Can I use a Montenegro eSIM on a day trip to Dubrovnik or Albania? No, a Montenegro plan works in Montenegro only; Croatia and Albania need their own plan.
- Which networks does ONE eSIM use in Montenegro? m:tel and T-Mobile, both with 5G where available.
- How much is the cheapest Montenegro eSIM? ONE eSIM's 1 GB plan costs $2.61 and lasts 7 days; 5 GB is $9.90 for 30 days.
- Can I keep my home number working? Yes. Most eSIM phones are dual SIM, so calls and texts stay on your home number while the eSIM handles data.
How we check prices
We read each provider's public Montenegro page on 4 November 2026 and took its cheapest plan at or above each size, in US dollars before any coupon, with the validity in brackets; ONE eSIM prices are our live list prices on the same day. Prices move, so we re-check every month and keep the date on the page and in the short answer. If a number is out of date, write to support@oneesim.app and we will correct it.
