Learning how to use an eSIM in Montenegro begins with three separate stages: checking that the phone is compatible, installing the profile over Wi-Fi and connecting it to a supported network after arrival. Complete the first two checks before travelling so that only a few settings remain to be changed in Montenegro.
The same travel eSIM can serve Podgorica, the Bay of Kotor, Budva and other included destinations, but the actual connection depends on the plan, partner network, phone and local terrain. Confirm that Montenegro appears in the live plan details rather than assuming that every European eSIM includes it.
NoveSIM travel eSIMs provide mobile data. We do not provide a Montenegrin telephone number or conventional calls and SMS, although maps, email, WhatsApp and other supported internet apps can use the data connection.
Quick answer: Check that your unlocked phone supports eSIM, install the profile on stable Wi-Fi before departure and keep it installed. In Montenegro, switch on the travel line, select it for Mobile Data, enable Data Roaming on that line and leave Network Selection on Automatic.

The practical sequence is to verify the device and plan, install the profile once, then configure the travel line after arrival. The iPhone and Android instructions below show where those steps differ.
Check the Plan and Phone before Installation
Start with the live Montenegro eSIM plans. Check the destination list, allowance, validity, activation rule, hotspot terms and available network information for the exact option. These details can differ between plans and may change.
Confirm the exact model and regional variant on the NoveSIM compatible-device list. A model family name is not always enough because eSIM availability can vary by country of sale, carrier configuration and device edition.
The phone must also be carrier-unlocked. An eSIM menu proves that the handset contains eSIM functionality, but it does not prove that another provider’s profile is permitted. If the phone came from a mobile operator and its lock status is unclear, ask that operator before buying a travel plan.
Installation and Activation Are Different
| Stage | What happens | Best timing |
|---|---|---|
| Installation | The eSIM profile is added to the phone. | Before departure on reliable private Wi-Fi. |
| Activation | The plan begins according to its stated activation rule. | Follow the order instructions. |
| Registration | The phone connects to an authorised partner network. | After arrival in Montenegro. |
Do not activate or test a plan early unless its terms allow it. Some plans start when installed, while others start after the first connection to an eligible network. The order email and product page take priority over general instructions.
How to Install a Montenegro eSIM on iPhone
Apple may use the wording Cellular or Mobile Service, depending on device language and software version. With the QR code available on another screen or printed page:
- Connect the iPhone to stable Wi-Fi.
- Open Settings and choose Cellular or Mobile Service.
- Tap Add eSIM.
- Choose the QR-code option and scan the code once.
- Follow the prompts until the new mobile plan appears.
- Label the line clearly, for example Montenegro Travel.
- Keep the primary line as the default voice line if you still need its number.
- Turn off Allow Cellular Data Switching.
If the QR code is displayed on the same iPhone, use the installation method supplied with the order. The separate iPhone installation guide explains the available menu paths.
How to Install a Montenegro eSIM on Android
Android menu names vary between Samsung, Google Pixel and other manufacturers. Look for SIM Manager, SIMs or Mobile Network:
- Connect the phone to stable Wi-Fi and open Settings.
- Open Connections, Network & Internet or the equivalent menu.
- Select SIM Manager or SIMs.
- Tap Add eSIM, Add SIM or Download a SIM.
- Scan the supplied QR code once and complete the prompts.
- Name the new line Montenegro Travel.
- Disable automatic or adaptive mobile-data switching if offered.
Some Android devices support eSIM only in particular markets. If the option is absent, use the device compatibility checks before attempting installation again.
Settings to Use after Arriving in Montenegro
Leave Airplane Mode, then give the handset time to detect local networks. Open the SIM settings and apply this starting configuration:
| Setting | Recommended selection |
|---|---|
| Travel eSIM line | On |
| Mobile Data | Montenegro travel eSIM |
| Data Roaming on travel eSIM | On |
| Data Roaming on primary SIM | Off |
| Automatic data switching | Off |
| Network Selection | Automatic |
Wait several minutes before changing advanced settings. Test a website or map rather than a telephone call: a data-only eSIM may be working correctly even though it cannot place carrier calls. The dedicated Montenegro eSIM activation guide explains what happens after installation.
Using Two SIMs without Accidental Roaming
A compatible dual-SIM phone can keep the home line available while the eSIM handles internet traffic. This can preserve access to the existing number, but the home carrier may still charge for calls, voicemail or SMS activity abroad.
Select the travel eSIM explicitly for Mobile Data, turn off data switching and keep Data Roaming disabled on the primary line. If receiving an authentication message is essential, check the home carrier’s Montenegro tariff beforehand; Montenegro is not part of the EU Roam Like at Home area.
Coverage on Coastal and Mountain Routes
Montenegro’s mountainous geography matters. A phone may connect well in Podgorica, Tivat, Kotor or Budva yet show weaker or intermittent service on mountain roads, inside stone buildings, around national parks or in sparsely populated areas. No national coverage statement guarantees service at every stop.
Leave Network Selection on Automatic unless NoveSIM Support provides another instruction. Whether 4G, 5G or hotspot use is available depends on the plan, partner network, device, radio bands, location and current conditions. Download the first route, accommodation details and tickets offline before driving beyond the main towns. The Montenegro mobile internet guide compares eSIM, local SIM, roaming and Wi-Fi.
If the eSIM Does Not Connect
- Confirm that the Montenegro plan is active and within its validity period.
- Check that the travel eSIM line is switched on and selected for Mobile Data.
- Enable Data Roaming on the travel line, not the primary SIM.
- Disable automatic data switching.
- Keep Network Selection on Automatic and wait several minutes.
- Toggle Airplane Mode briefly, then turn it off and test again.
- Restart the phone if network registration still does not appear.
If manual APN entry is required for a NoveSIM plan, enter data.esim and leave username and password blank. Do not use a domestic operator’s APN and do not delete the installed eSIM unless NoveSIM Support specifically instructs you to do so. The Montenegro troubleshooting guide covers signal, APN and data-line checks in more depth.
Before Leaving Wi-Fi
- Save the order email and instructions offline without sharing the QR code.
- Confirm the plan includes Montenegro and covers the final travel day.
- Download offline maps for mountain drives and border routes.
- Pause photo backup, app updates and automatic video downloads if data is limited.
- Keep another way to reach accommodation or transport providers.

FAQ
When should I install my Montenegro eSIM?
Install it before departure on stable private Wi-Fi unless the plan instructions specify different timing. Installation adds the profile; activation follows the rule for the purchased plan.
What settings should I change in Montenegro?
Switch on the travel eSIM, select it for Mobile Data, enable Data Roaming on that line, disable automatic data switching and leave Network Selection on Automatic.
Can I keep my usual number while using the eSIM?
Usually yes on a compatible dual-SIM phone. The eSIM supplies data while the primary line retains its number, but calls, SMS and voicemail remain subject to the home carrier’s roaming charges.
Should I delete and reinstall an eSIM that does not connect?
No. First verify the active plan, data line, Data Roaming, network selection and APN. Delete the profile only if NoveSIM Support specifically instructs you to do so.
Final Recommendation
Knowing how to use an eSIM in Montenegro safely starts before the journey: verify the handset and lock status, read the activation rule and install the profile once on reliable Wi-Fi.
After arrival, use the travel line for Mobile Data, enable Data Roaming only on that line and allow automatic network selection time to register. Keep the home SIM from taking over data and understand its separate roaming costs if it remains enabled.
Save route information offline for Montenegro’s mountain and coastal journeys. If the connection fails, preserve the installed profile and work through the reversible settings checks before contacting NoveSIM Support.
