Telecommunication access in developing countries like Bangladesh has economic and social benefits. Studies have found that phones enable important financial discussions for rural families receiving remittances. In Bangladesh, phones have also been used to generate income by reselling minutes. However, these income benefits are not seen everywhere. Other research found telephones save time and costs for travel or postage but have little direct impact on income generation, except for wealthier individuals. Phones also strengthen social networks which are important for informal economies, helping to access information on jobs, remittances, and housing. While business uses are important, most phone use in developing countries is for social contact with family and friends.
