Orange Cameroon is a mobile carrier operating in Cameroon since 1999. The company is a subsidiary of French operator Orange S.A.
The company operates 2G GSM services over the 900 MHz band and 3G UMTS over the B1 (2100 MHz) band. 4G LTE was launched in December 2015 over the B3 (1800 MHz) band. There has been some controversy around the actual launch date with many suggesting 4G LTE did not go live until April 2016.
