Even before the first naira changes hands or the first customer calls, Musa Lekki reaches for his phone. It is 5:32 a.m. on a Tuesday, and like many smartphone users, he begins his day with a glance at his phone screen. The 42-year-old provisions trader lives in Yola, northeastern Nigeria, and runs a small wholesale business supplying neighbouring shops and customers with rice, beverages, and household goods. As he unlocks his phone, there is already work waiting for him.
