Travel eSIM Montenegro

No, the Montenegro travel eSIM is data-only. It won’t give you a cellular voice line. If you want to call, just fire up WhatsApp, Telegram, or FaceTime using your data allowance.

Yes! Your Montenegro eSIM can be installed as early as 30 days before you travel. It won’t start until you touch down in Montenegro.

Installing beforehand means no setup stress on arrival, and it won’t use any data or days until you land.

If you get an activation warning on iPhone when installing before arriving, that’s normal - check our eSIM Troubleshooting Guide for details.

No, these eSIMs only provide data access and do not assign you a phone number. To make calls, you will need to use internet based apps such as WhatsApp or Messenger.

Your eSIM will activate automatically when you arrive in Montenegro. We recommend installing your Montenegro Travel eSIM in advance (installation is different from activation).

Just scan the QR code you receive or install via the ZenSim app using WiFi. Once you touch down in Montenegro, your eSIM will go live automatically.

Your Montenegro eSIM will start working the moment you land in Montenegro-it auto-activates if installed prior to departure.

If you install it after arrival, it will connect immediately.

Hands down, a travel eSIM beats roaming in Montenegro. Here’s why:

Cheaper Data: Pay local prices rather than roaming surcharges from your home network.

Instant Setup: No waiting for physical SIM delivery - your eSIM is ready the minute you land.

Full Expense Control: Track data usage and spending in - app, so you avoid surprise fees.

No, your plan only starts upon landing in Montenegro. Installing beforehand ensures you’re ready to go as the activation will happen automatically.

You’ll need WiFi for installation, so do it before departure and this way you will be connected as soon as you arrive.

Yes, you can. Around 99 percent of our eSIMs allow quick and easy top ups through the ZenSim app. You can add more data, increase the days, or even include a different destination on the same eSIM right from the Zen Garden.

Open the app, go to the Zen Garden area, and you’ll see the top up button waiting for you.

Top up pricing: Montenegro top up plans follow the same pricing as on the website, minus a 10% discount.

Travelling for a while: If your trip lasts more than 30 days, you can queue multiple top ups. None of them will interrupt your current plan because each one only activates when the previous eSIM expires.

Travelling to more destinations: Most eSIMs let you attach extra countries via a top up. For example, if you're heading home from Europe and stopping in Singapore, you can add Singapore to your Europe eSIM and it will switch on once you arrive.

After activation in Montenegro, your eSIM won’t usually work elsewhere. Each country typically needs its own eSIM unless you're using a regional one.

To make travel easier, try one of our regional Travel eSIMs - they work across entire continents.

Easy - once you have purchased your Montenegro eSIM, you will be able to access your unique referral URL. From there, simply share it with your people, and when they sign up (provided they're a new customer) you will both save A$5.

For each person you refer you will earn a A$5 voucher on your account which will be automatically applied to your next purchase and as we mentioned your referee will also save A$5 on their order.

The ZenSim app lets you track referrals and copy your referral URL anytime. See our terms for more information.

Only on unlimited plans, and only past 3GB in a single day - which is a generous amount, considering most travellers use less than 1GB daily.

If you do go past 3GB, your speed will be limited to 1Mbps until midnight, when it resets and you're back to full speed again.

Fixed-data plans (10GB, 20GB, etc.) don't have any daily throttling - you're free to use your data at whatever pace suits you until the plan's used up. We'll flag it before you run out, and topping up takes just a couple of taps in the ZenSim app.

It won't activate the moment you buy it - your Montenegro eSIM won't touch your data or days until you actually arrive, so there's no downside to installing it in advance.

As long as it's installed beforehand, it'll activate itself the second you touch down, and that's the moment your plan officially begins.

As for running out - your eSIM expires once your data or days are gone, whichever comes first (just the days, if you're on unlimited). Buy a 30-day plan and it'll run out 30 days after arrival in Montenegro, not 30 days after purchase.

Simplest way is to pop your phone into our eSIM compatibility checker - it'll tell you straight away whether it's good to go with our Montenegro eSIM and the networks behind it.

If you're still unsure after that, get in touch with us and we'll help you figure it out. And just in case your phone isn't compatible after all, our refund policy means you'll get a full refund - so go ahead and grab a plan without the worry.

We sure do - it's covered under our 100% money back guarantee.

Cancelled trip, incompatible phone, or your travel plans just changing - all of these situations qualify.

Check out our refund policy for the full details, but the bottom line is: if you can't install or use the eSIM, you'll get every cent back.
