The day started well for Sayi Gharat. The 9-year-old schoolgirl managed to connect easily to her online science class, as she sat on a daybed in her grandmother's home in western India.

But Sayi knew she would not be able to stay in the same spot for long due to the shaky mobile internet connection she relied on for her education as classes in Dunge village and across India moved online when COVID-19 struck in March 2020.

"Sometimes the network is good, sometimes it's not good; she has to move from one room to another, from one corner to another, and even go outside," said Sayi's grandmother, Chandrakamalkar Gharat.
