A new international study produced by the GSM Association and the Cherie Blair Foundation for Women shows a large gender gap in mobile adoption in low and middle-income countries. Not surprising, perhaps. A Pakistani journalist once told me that mobile penetration in his country is about 50 percent. When I said that seemed surprisingly low, he said that many men don't like their wives to have phones. The "Women and Mobile: A Global Opportunity" report [PDF] says women represent an untapped market for mobile operators. Women with mobile phones describe a number of benefits from mobile use, including feeling safer and more independent.
