Roaming charges in Montenegro depend on the traveller’s home carrier because Montenegro is outside the EU and EEA. A plan that includes regulated roaming in Croatia may move into a different tariff zone after crossing the Montenegrin border.
Some carriers include Montenegro in a special Western Balkans or travel bundle, but this is voluntary. The operator’s current destination list, allowance and renewal rules determine the actual cost.
NoveSIM Montenegro eSIMs are data-only and do not provide a local number, ordinary calls or carrier SMS.
Quick answer: Montenegro is not automatically covered by EU Roam Like at Home. Check whether your exact tariff names Montenegro, the daily-pass trigger and the rates for data, calls and SMS. With a travel eSIM, disable roaming and automatic data switching on the primary line while enabling roaming only on the travel eSIM.

Why roaming charges in Montenegro are different
EU roaming regulation is based on membership and legal scope, not geography. Montenegro’s position in Europe does not automatically place it in the EU roaming area. Carrier bundles can be broader, but their inclusion can change.
Charges to Check
- data price or daily-pass fee;
- high-speed allowance and overage;
- outgoing and incoming call rates;
- SMS charges and voicemail treatment;
- pass renewal time and time zone;
- border-network and maritime-network exclusions.
Save the tariff before travel. A network name on the screen proves registration, not that usage is included.
Prevent Accidental Data Roaming
Select the travel eSIM for Mobile Data, enable Data Roaming on that line and disable mobile-data switching. Keep roaming off on the primary SIM unless its charges are understood. Background updates can trigger a pass without deliberate browsing.
Watch Border Areas
Near Croatia, Bosnia and Herzegovina, Serbia, Kosovo or Albania, a phone may detect a network across the border. Leave the travel line on automatic when its plan supports the route, but check the displayed network if an unexpected roaming message appears. Avoid maritime or satellite networks unless explicitly included.
FAQ
Is Montenegro covered by EU roaming?
Not automatically under EU Roam Like at Home rules. An individual carrier may include it in a separate commercial bundle.
Can I receive calls on my home number?
The home line may remain active, but incoming calls and voicemail can be chargeable. Check the home tariff.
Does a Montenegro eSIM include calls?
NoveSIM travel eSIMs are data-only. Internet calling apps can use the connection where available.
How do I keep the home SIM from using data?
Choose the travel eSIM for mobile data, turn off automatic switching and keep Data Roaming disabled on the home line.
Final Recommendation
Do not infer roaming charges in Montenegro from an EU allowance used elsewhere. Verify the exact country, pass trigger, call rates and overage directly with the home carrier.
For predictable mobile-data spending, prepare a local or travel option before crossing the border and configure the primary line so it cannot silently take over data.
