What are the expected roaming costs for Russia (Moscow, St. Petersburg) with an EU, UK, or US mobile plan?

When planning a route through Russia, particularly to cities like Moscow or St. Petersburg, relying on your existing EU, UK, or US mobile plan for data is not recommended. These regions fall outside the typical 'roam like at home' agreements, meaning your home provider will levy substantial international roaming charges. You could face exorbitant per-megabyte rates, turning a simple map check or message into a costly expense. eSIM Routes offers a more predictable and budget-friendly data solution, ensuring your itinerary stays on track without unexpected bills.
