NorthESIM generally offers good coverage along the scenic Transfăgărășan highway in Romania. However, for sections with the highest tunnels, particularly around Bâlea Lake, we advise downloading offline maps as a precaution. This ensures uninterrupted navigation through one of Europe's most spectacular roads, even if the signal temporarily diminishes in isolated spots.
