In 2013, the communications sector was the fastest growing in Tanzania, expanding 22.8 percent; however, the sector accounted for only 2.4 percent of gross domestic product that year.
As of 2011, Tanzania had 56 mobile telephone subscribers per 100 inhabitants, a rate slightly above the sub-Saharan average. Very few Tanzanians have fixed-line telephones.
Approximately 12 percent of Tanzanians used the internet as of 2011, though this number is growing rapidly. The country has a fibre – optic cable network that replaced unreliable satellite service, but internet bandwidth remains very low.
