Connectivity within bomb shelters in Ukraine can vary. In deeper underground metro stations, such as those in Kyiv, cellular service or Wi-Fi is often available. However, in private basement shelters or structures with thick concrete, signal penetration might be limited. WorldESIM aims to connect to the strongest available networks, but physical obstructions can sometimes impact service. It's advisable to check for local Wi-Fi options if cellular signal is weak.
