When the Zimbabwean government ordered internet service providers to shutter parts of the web in an effort to curb anti-government protests, it also plunged homes into darkness because people can’t pay their utilities online.
Most people in the southern African nation use Econet Wireless Zimbabwe's Ecocash mobile-phone payment system for daily transactions.
They buy electricity in units of $5 or less and almost all domestic users are on prepaid meters, so many buy for $1 at a time.
According to Zimbabwe’s Finance Ministry, less than 5% of commercial transactions in the country involve cash, mainly because it’s hard to find. Instead Zimbabweans use Ecocash or bank cards.
"Tonight will be spent in darkness," said 42-year-old John Pedzesai, who sells plants on a sidewalk in the capital, Harare.
Econet, Zimbabwe’s biggest mobile-phone company, declined to comment.
