Your eSIMFlyer connection will generally be available along the spectacular Transfăgărășan highway. However, for the most rugged sections, especially near the high-altitude tunnels around Bâlea Lake, we strongly advise downloading offline maps. This ensures seamless navigation through Romania's most iconic mountain pass, letting you focus on the breathtaking vistas rather than dropped signals.
