Cheapest unlimited eSIM for Montenegro? From €6.95 for 3 days (October 2026)

If you are travelling to Montenegro, the good news is that from €6.95 you already get an unlimited eSIM for 3 days, with no complications or surprise bills when you get back. At Roam2Go you will find unlimited plans for 3, 5, 7, 10 and 30 days — as well as GB-based options if you prefer to pay for just what you need — all activatable from your phone before you board the plane.

Worth noting: Montenegro is not part of the European Union, which means the “roam like at home” rule does not apply there, and many European operators charge additional roaming fees the moment you cross the border. Check with your usual provider before you leave and, if needed, a country-specific eSIM is the cleanest solution.

Why an eSIM for Montenegro makes sense

Montenegro has grown enormously as a destination in recent years: the Bay of Kotor, Budva, Durmitor National Park… yet roaming infrastructure does not always keep pace. Because the country sits outside the European roaming area, many continental tariffs charge extra fees there, often without much warning. A prepaid eSIM with a fixed price in euros means you never have to watch the counter or face an unexpected bill.

What’s more, with an eSIM you do not need to swap your physical SIM: your home SIM stays in your phone and you can switch between them whenever you like. Very handy, especially if you need to receive calls from your home country.

Unlimited plans for Montenegro: 3, 5 and 7 days

If you know you will be using your phone intensively — real-time maps, cloud photo uploads, video calls or streaming — unlimited plans are the ones that will give you the most peace of mind. These are the shortest durations Roam2Go offers:

• Unlimited 3 days – €6.95: perfect for long weekends or express getaways to Kotor or Budva.
• Unlimited 5 days – €9.99: ideal for a short week covering the country’s main highlights.
• Unlimited 7 days – €14.50: the best option if you are doing a full road trip or combining Montenegro with a neighbouring country (where you will need to activate a separate plan).

For longer stays, the product page also has unlimited plans for 10 days (€52.88) and 30 days (€79.86).

The price is fixed in euros: what you see when you buy is what you pay, with no roaming extras or hidden charges on your return.

All Roam2Go plans for Montenegro

If your usage is more moderate — occasional map checks, WhatsApp and not much else — GB-based plans may well be enough and they come at a great price. Here is the full table of available plans:

Which plan to choose based on your trip

Weekend break (2–3 days)

The 3-day unlimited plan at €6.95 is the natural choice. If you know you will use your phone sparingly, the 1 GB / 7-day plan at €1.95 may be enough for occasional map checks and messaging.

One-week trip

The 5-day unlimited plan (€9.99) works well for a typical week, especially if you will be in transit for the last couple of days. If you want full 7-day coverage without a second thought, the 7-day unlimited plan at €14.50 is the most comfortable option.

Long stay or digital nomad

For stays longer than a week, the 10 GB or 20 GB 30-day plans are usually sufficient if you are not doing heavy streaming. If you work remotely and rely heavily on your connection, the 30-day unlimited plan gives you more headroom, though you will want to consider whether your daily usage is very high.
