Before you buy: straight answers
What happens at the Croatian border?
Your phone joins a Montenegrin network. Use the eSIM for data and turn data roaming off for your own SIM.
How much data do I need for a week?
About 3 to 5 GB.
Buying tips for US travelers
- You pay in US dollars, so there is no currency conversion. Your card issuer may still apply its own fees for a merchant outside the US.
- Phones bought on a payment plan are often locked to AT&T, Verizon or T-Mobile until paid off. Check yours is unlocked before you buy.
- Turn off data roaming on your US line before you land. AT&T’s Day Pass and Verizon’s TravelPass charge on each day you use your phone abroad.
- Keep your US line on for texts and two-factor codes; iMessage, WhatsApp and FaceTime work over the eSIM’s data.
What your trip to Montenegro costs
Each network’s lowest published option for Montenegro, next to the Graba SIM plan with about 0.7 GB a day (regular use) for the whole trip. Network prices use your US plan and include calls and texts; the eSIM is data only.

See day passesHow we choose these plans
For each trip we pick the current plan that costs the least while lasting the whole trip and gives about 0.3 to 0.7 GB a day, enough for maps, messages and social media. A plan may last longer than the trip. Everyone uses data differently, so check your phone’s recent data use. “Best value” only appears when that plan also costs the least per GB of all the plans that fit.
