Montenegro has three mobile operators: MTEL, One and Crnogorski Telekom. The eSIM providers you can buy do not all connect to the same number of them, and in a country this mountainous, that difference is worth understanding before you pay.
It’s the main thing separating the four options below, along with price. Roaming here is charged outside your domestic bundle, since Montenegro sits outside the EU roam-like-at-home zone, so an eSIM is the sensible move either way. The question is which one.
We compared all four on price, data allowances, network access, tethering and plan length. Here’s the best eSIM for Montenegro in 2026.

Best eSIM for Montenegro: How the Four Compare
We assessed each provider on the same criteria: what a week and a month of data actually cost, how many Montenegrin networks it can reach, whether you can share the connection, and how long the plans run. The results below are ordered by overall value.
1. Saily
Pros
- Cheapest entry plan at $3.39
- Best monthly plan of the four
- Ad blocker and virtual location included
- Thirty days to activate, uncapped hotspot
Cons
- Unlimited plan is beaten on price
- Data only, no Montenegrin number
Saily is the best eSIM for Montenegro on balance, mostly because its metered plans are priced better than anyone else’s and unlimited data is rarely necessary in a country this compact.
The plan that matters is 10 GB over thirty days at $18.69. It’s the cheapest monthly allowance in this comparison, undercutting Ubigi’s equivalent, and it covers a fortnight of navigation, messaging and photo uploads without any rationing. Below it, 5 GB for a month is $11.04 and 3 GB is $7.64. Entry level is 1 GB over seven days at $3.39.
Every Saily plan includes an ad blocker and a virtual location tool, both inherited from Nord Security, the company behind NordVPN. On public Wi-Fi that’s a practical benefit rather than a marketing line.
The exception is unlimited data, priced at $41.64 for fifteen days. Ubigi does the same for less, and we’d point you there if that’s what you want.
Tethering is uncapped, so one plan can serve two travelers. The activation window is thirty days, meaning you can buy in advance and the plan only starts once your phone connects in Montenegro. Current offers are listed on our Saily promo code page.

2. Ubigi
Pros
- Unlimited data from $26.10 with the code
- Two networks, MTEL and One
- Unlimited data sharing
- QR code activation on arrival
Con
- No SMS or calling
Ubigi is the best eSIM for Montenegro if you want unlimited data, and it also gives you access to two of the country’s three networks, MTEL and One. Your phone takes whichever signal is stronger, which is worth something in the mountains and around the Bay of Kotor.
A week of unlimited data costs $29, or $26.10 with the GIZMODO code. Fifteen days is $44, which the code takes to $39.60. Both undercut Saily and Airalo at the same durations.
On metered plans it’s close but not quite ahead. The best seller is 10 GB over thirty days at $21, or $18.90 with the code, which lands just above Saily’s $18.69. The same 10 GB over a week is $19, or $17.10. Three gigabytes over fifteen days is $9, or $8.10, and the entry plan is 1 GB for seven days at $5, or $4.50.
Tethering is unlimited. The QR code arrives by email and the plan only starts when you connect in Montenegro. There’s no local phone number, which is standard across all four providers here.
3. Holafly
Pros
- Access to all three Montenegrin networks
- Every plan is unlimited
- Pay by the day, from $5.90
- 24/7 live chat
Cons
- Hotspot capped at 500 MB a day
- Expensive over a longer trip
- No Montenegrin number
Holafly has the strongest coverage on paper. It connects to MTEL, One and Crnogorski Telekom, which is every operator in the country. No other provider here does that. If your itinerary involves Durmitor, the northern canyons or anywhere the road narrows, this is a real technical advantage rather than a claim.
The pricing model is simple: you choose the number of days, the data is unlimited, and the rate starts at $5.90 per day and falls as the trip lengthens.
The limitation is tethering, capped at 500 MB per day. That effectively rules out sharing one plan between two people, so a couple would need to buy two, which changes the cost comparison significantly. Over a week or more, Ubigi’s unlimited plan at $26.10 is the cheaper route to the same outcome.
4. Airalo
Pros
- Plans from 3 to 30 days
- Unlimited tethering
- Activates itself on arrival
- Usage tracking in the app
Cons
- MTEL only, and 4G only
- More expensive than Ubigi at every duration
- The 30-day plan costs $89
Airalo’s Montenegro range is complete but consistently expensive. Unlimited data runs $20.50 for three days, $28 for five, $36.50 for seven, $37 for ten, $49 for fifteen and $89 for thirty.
Two things stand out. The ten-day plan at $37 costs fifty cents more than the seven-day plan, which makes the seven-day option pointless. And the thirty-day plan at $89 is more than double what Ubigi charges for fifteen days of the same thing.
The network is MTEL alone, limited to 4G, which is the narrowest access of the four providers here. In practice LTE is fine across the coast and the main routes, but you have no fallback if the signal drops.
What Airalo does well is convenience. The plan activates itself when you land, tethering is unlimited, and the app tracks usage in real time. If Montenegro is one stop on a longer route, the regional plans covered in our guide to the best eSIM for Europe are usually better value than four separate country plans.
How to Choose Your Montenegro eSIM
Four questions decide it:
- How much data do you use? A 10 GB monthly plan covers most two-week trips. Saily’s costs $18.69 and Ubigi’s $18.90, both far cheaper than any unlimited option.
- Do you want unlimited anyway? Ubigi is the cheapest at $26.10 for a week with the code, and it reaches two networks rather than one.
- Where are you going? Coastal towns and main roads are well covered by all four. For the northern mountains, Holafly’s three-network access is the safest, and Ubigi’s two-network setup is the best compromise on price.
- Are you sharing? Saily, Ubigi and Airalo tether without limits. Holafly caps you at 500 MB a day, which means one plan per person.
Verdict: The Best eSIM for Montenegro
Saily is the best eSIM for Montenegro for most travelers. Its 10 GB monthly plan at $18.69 is the cheapest useful allowance available, tethering is uncapped, and the 15% GIZMODO discount is already reflected in the price.
Ubigi is the better buy if you want unlimited data or two networks instead of one. At $26.10 for a week with the code, it’s the cheapest limitless plan in this comparison.
Holafly is the coverage specialist here, and the only provider reaching all three Montenegrin operators, but the 500 MB tethering cap and the daily pricing make it hard to justify beyond a short trip. Airalo is easy to use and the most expensive at nearly every duration.

Frequently Asked Questions
What is the best eSIM for Montenegro?
Saily is the best eSIM for Montenegro overall. Its 10 GB plan for 30 days costs $18.69, which is the cheapest monthly allowance of the four providers, and tethering is uncapped. Ubigi is the better choice for unlimited data, starting at $26.10 for 7 days with the GIZMODO code.
Which networks do Montenegro eSIMs use?
Montenegro has three operators: MTEL, One and Crnogorski Telekom. Holafly reaches all three, Ubigi connects to MTEL and One, and Airalo runs on MTEL alone. More networks means your phone can switch to whichever signal is stronger, which matters most in the northern mountains.
Are roaming charges in Montenegro high?
Montenegro is outside the EU roam-like-at-home zone, so your domestic bundle does not follow you there and you are billed outside your normal allowance. An eSIM connects you to a local operator such as MTEL or One at local data rates instead.
What is the cheapest eSIM for Montenegro?
Saily has the cheapest entry plan at $3.39 for 1 GB over 7 days, and the cheapest monthly plan at $18.69 for 10 GB. For unlimited data, Ubigi is the cheapest at $29 for 7 days, or $26.10 with the GIZMODO code.
Do I need unlimited data in Montenegro?
Most travelers do not. A 10 GB plan over 30 days is enough for a two-week trip built around navigation, messaging and photo uploads, and it costs less than half the price of an unlimited plan. If you do want unlimited data, Ubigi is the cheapest option at $26.10 for a week with the code.
Which currency can I pay in?
Saily, Ubigi, Holafly and Airalo all let you choose your billing currency at checkout, with USD, EUR and GBP available on every provider. Picking the currency of your card avoids an extra conversion fee from your bank.
