Final answer:
Mobile phone use in Africa has seen a significant rise, with a fivefold increase over the past decade, enhancing communication, economic opportunities, and access to banking and entrepreneurship resources, while landline use has remained static.
Step-by-step explanation:
The statement that mobile phone use in Africa has increased significantly while landline use has not changed much is true. Over the past ten years, there has been a fivefold increase in mobile phone access in Sub-Saharan Africa, impacting over a third of the population in the region.
This surge in mobile connectivity facilitates various benefits for the residents, from improving market access for farmers and fishers to enabling secure monetary transactions through mobile banking.
The Grameen Foundation's shared-phone program and corporate initiatives by companies like Vodafone and Masbabi have propelled mobile technology access, offering tools for innovation and entrepreneurship. The rapid adoption of mobile phones is transforming communities, bypassing traditional infrastructure challenges, and fostering economic growth in Africa's poorest countries.
