Montenegro eSIM: Stay Connected Across the Adriatic Coast
From Kotor's bay to Durmitor's peaks, skip roaming fees and get online the moment you land with a Montenegro eSIM.
Picture winding along the Bay of Kotor, the Adriatic glittering below, your phone already online before you reach the hotel. That is what a Montenegro eSIM gives you: instant data, no SIM swap, no roaming shock.
Why use an eSIM in Montenegro
Montenegro is small but mountainous, and patchy roaming plans can leave you stranded between coast and canyon. An eSIM loads digitally, activates in minutes, and keeps you connected for maps, ferries, and last-minute restaurant bookings.
Montenegro has three reliable operators: Crnogorski Telekom, Telenor, and m:tel. All offer solid 4G/LTE nationwide, with growing 5G in major hubs. Expect strong signal in Podgorica, Budva, and Kotor, plus good coverage along the coast and main highways. Remote mountain areas like Durmitor can be spotty, as anywhere with steep terrain.

Frequently asked questions
Does an eSIM work in Montenegro?
Yes. Montenegro has modern mobile networks with strong 4G/LTE and growing 5G, so a HelloSIM travel eSIM works well across the country. You just need an eSIM-compatible, carrier-unlocked phone.
Is my phone compatible with a HelloSIM eSIM for Montenegro?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S, Note, and Z models. The phone must also be carrier-unlocked to accept a HelloSIM eSIM.
How do I check if my phone supports eSIM before buying?
On iPhone go to Settings, General, About and look for an Available eSIM or EID entry. On Android, search Settings for eSIM or dial *#06# to see if an EID number appears alongside the IMEI.
How do I buy and install a HelloSIM eSIM for Montenegro?
Order the Montenegro plan on HelloSIM, then you receive a QR code and installation details by email. Scan the QR code in your phone settings to install the eSIM, ideally over Wi-Fi before you travel.
How do I install the eSIM QR code on an iPhone?
Go to Settings, Cellular (or Mobile Data), Add eSIM, then Use QR Code and scan the code from HelloSIM. Label the line something like Montenegro and follow the prompts to finish.
How do I install the eSIM on an Android phone?
Open Settings, Network and internet (or Connections), SIMs, then tap Add eSIM or Download a SIM instead, and scan the HelloSIM QR code. Menu names vary slightly by brand such as Samsung, Pixel, or Xiaomi.
Can I install the eSIM without scanning a QR code?
Yes. HelloSIM also provides manual details (an SM-DP+ address and activation code) that you can type in under the Add eSIM or Enter Details Manually option if you cannot scan the QR code.
Should I install the eSIM before flying to Montenegro or after landing?
Install it before you fly while you have reliable Wi-Fi, but wait to activate or start the plan until you arrive. Installing early avoids doing setup on airport or hotel Wi-Fi.
When should I activate my Montenegro eSIM?
Most HelloSIM plans start when the eSIM first connects to a Montenegro network, so activate on arrival. Some plans begin at first use or after a set window, so check the plan details before you travel.
Which networks does HelloSIM use in Montenegro?
HelloSIM connects through major Montenegrin mobile operators, which include Crnogorski Telekom, One, and m:tel. Your device automatically registers on a partner network, so you do not choose it manually.
Is there good mobile coverage across Montenegro?
Coverage is strong in cities and along the coast, including Podgorica, Budva, Kotor, Tivat, and Herceg Novi. Signal can weaken in the high mountains and remote areas of Durmitor and the northern canyons.
Is 5G available in Montenegro?
Yes, 5G is live in and around larger cities and coastal hubs, and it is still expanding. Where 5G is not present you will use fast 4G/LTE, which is widely available.
How fast are typical data speeds in Montenegro?
In towns and along the coast you can usually expect comfortable 4G speeds for maps, streaming, and video calls, with faster speeds where 5G is available. Speeds drop in remote mountain areas.
How much data do I need for a week in Montenegro?
For a week of maps, messaging, social media, and some streaming, many travelers are comfortable with roughly 3 to 5 GB. Heavy video or hotspot use can push that higher.
What data plans does HelloSIM offer for Montenegro?
HelloSIM offers a range of data bundles with different allowances and validity windows, typically from a few days up to about 30 days. Pick the size that matches your trip length and usage.
How much does a Montenegro eSIM cost?
Prices vary by data amount and validity, so smaller short-trip bundles cost less than large or longer plans. Check the live prices on the HelloSIM Montenegro page for current options.
How long is a HelloSIM Montenegro plan valid?
Validity depends on the bundle you choose and commonly ranges from a few days up to about 30 days. The countdown usually begins when the plan activates on a local network.
Can I use my HelloSIM eSIM as a hotspot in Montenegro?
Yes, HelloSIM plans support tethering, so you can share your data with a laptop or tablet via personal hotspot. Remember that hotspot use consumes your data allowance quickly.
Can I keep my home phone number while using the eSIM?
Yes. The eSIM runs alongside your regular SIM in dual-SIM mode, so you keep your home number for calls and texts while using HelloSIM data for internet in Montenegro.
How do I set up dual SIM so I do not get roaming charges?
Keep your eSIM set as the data line and turn off data roaming on your home SIM. You can leave your home line active for calls and texts if you want, but disable its mobile data to avoid surprise charges.
Do I need to change any APN settings for Montenegro?
Usually not, because HelloSIM configures the APN automatically. If data does not connect, HelloSIM provides the correct APN to enter manually in your eSIM line settings.
Do I need to turn on data roaming for the eSIM to work?
Yes. Because the eSIM uses partner networks, you must enable data roaming on the HelloSIM line. This does not create extra charges since the plan is prepaid.
Will I have internet at Podgorica or Tivat airport when I land?
Once your eSIM registers on a local network after landing, you should get data at Podgorica (TGD) and Tivat (TIV) airports. Enable the line and data roaming, and allow a couple of minutes to connect.
Can I make phone calls and send SMS with a HelloSIM eSIM?
HelloSIM data plans are data-only, so they do not include a local phone number for regular calls or SMS. You can call and message over the internet using apps like WhatsApp, Viber, FaceTime, or Signal.
How do I top up if I run out of data in Montenegro?
You can add more data through your HelloSIM account or buy an additional plan without swapping the eSIM. Top-ups apply to the same eSIM so you stay connected.
What happens when my data runs out?
Your connection simply stops passing data until you top up or buy a new bundle. You will not be charged overage fees because HelloSIM plans are prepaid.
Can I use my Montenegro eSIM in nearby countries?
A Montenegro-only plan is meant for use inside Montenegro. If you also plan to visit Croatia, Serbia, Bosnia, or Albania, choose a regional Balkans or Europe plan that lists those countries as covered.
Does a Montenegro eSIM work in the EU or does EU roaming apply?
Montenegro is not in the EU, so EU roaming rules do not apply. Use a Montenegro or wider regional plan rather than assuming an EU plan will cover it.
My eSIM shows no service in Montenegro, what should I do?
Confirm the line is turned on, data roaming is enabled, and airplane mode is off, then restart your phone. If it still fails, manually select a network like Crnogorski Telekom or One in your carrier settings.
The eSIM is not registering on a network, how do I fix it?
Toggle airplane mode on and off, reboot, and make sure the HelloSIM line is set as the active data line. Manually searching for and selecting a partner operator in Settings often resolves stubborn registration issues.
Can I install the eSIM now and use it on a future trip?
Yes, you can install early, but many plans only start counting once they connect to a Montenegro network. Confirm the activation policy so your validity window does not begin before your trip.
Can I use the same eSIM on my next visit to Montenegro?
If the eSIM profile is still installed, you can often top it up and reuse it for a future trip rather than installing a new one. Check that the plan or QR code has not expired.
What is the emergency number in Montenegro?
The general European emergency number 112 works in Montenegro. You can also reach police on 122, fire on 123, and ambulance on 124. Emergency calls connect even without an active data plan on your home SIM.
Is the eSIM a good option for a Kotor and Budva coastal trip?
Yes. Coverage along the Adriatic coast including Kotor, Budva, Tivat, and Sveti Stefan is strong, so a HelloSIM eSIM keeps you online for maps, ferries, and bookings throughout the coast.
Will I have signal on the mountain roads and in Durmitor National Park?
Main roads and towns generally have coverage, but signal can drop in deep canyons, high passes, and remote parts of Durmitor and the north. Download offline maps before heading into the mountains.
Should I download offline maps before my trip?
Yes. Saving offline maps of Montenegro in Google Maps or Maps.me is smart for winding coastal roads, mountain villages, and canyon areas where signal may be weak. It also saves data.
Can I get a refund if the eSIM does not work?
If you have not activated or used the eSIM, HelloSIM can typically help with a refund or replacement. Contact support with your order details, and reach out promptly if you hit a genuine technical problem.
Can I use the eSIM on my tablet or a second device?
You can install the eSIM on an eSIM-capable tablet, but each eSIM is meant for one device at a time. To connect multiple devices, use your phone as a hotspot or buy a separate plan.
Do I need a passport or local address to buy a HelloSIM eSIM?
No. Unlike buying a physical local SIM, a HelloSIM eSIM needs no registration, passport, or Montenegrin address. You buy online and install the QR code yourself.
What should I do right after landing in Montenegro to get online?
Turn off airplane mode, make sure the HelloSIM line is enabled with data roaming on and set as the data line, then wait a moment to register. Once connected you can open maps and messaging right away.
Is the currency in Montenegro relevant to my eSIM?
Montenegro uses the euro even though it is not in the EU, which is convenient for budgeting, but it does not change how your eSIM works. Your HelloSIM plan is prepaid regardless of local currency.
How many days before my trip should I set up the eSIM?
Installing a day or two before departure is plenty and lets you handle any setup over home Wi-Fi. Just remember activation typically happens when you land and connect in Montenegro.
