What this means
  • Your eSIM connects to local networks in Montenegro, but your data joins the internet in the UK. Apps and websites see a connection from the UK, so some may show that country’s language, prices or content.
  • Maps, GPS and taxi apps still know where you really are, because they use your phone’s location, not your internet location.
  • Handy for UK apps: banking, shopping and catch-up TV apps that check where you connect from see a UK connection, just like at home.

Questions about this plan

Is 20GB enough for 30 days in Montenegro?

For everyday use, yes: maps, social media and a short video call most days. Daily video streaming needs more.

What happens when the 20GB runs out?

Add a top-up to the same eSIM or buy another Montenegro plan to keep going.

Would a smaller Montenegro plan cost less?

The next size down, 10GB for 30 days, is £16.99: £1.70 per GB, more per GB than the 20GB plan, though less in total.
