Yes, this is a lifeline. South Africa has frequent, scheduled power cuts ("Load Shedding"), which instantly kills all Wi-Fi in hotels, Airbnbs, and cafes. Mobile towers, however, have backup batteries. An eSIM is the only reliable way to stay online, use Google Maps, or order an Uber when the power is out.
