Mobile subscribers in the Asia Pacific region have the cheapest mobile data service plans in the world, according to research firm Quantum-Web. Meantime, Latin America is home to the world's most expensive mobile data plans at an average of $23 per gigabyte – double that of Asia Pacific. North America is the second most expensive region in terms of mobile data pricing, followed by Africa, the Middle East and Europe.

Quantum-Web, which tracks 3G and 4G mobile broadband tariffs, found considerable pricing variation among individual operators.
