Prepaid Data SIM Card Wiki

Flag of the British Indian Ocean Territory.svg


The only inhabited island in the British Indian Ocean Territory is Diego Garcia. Almost the only people allowed to enter Diego Garcia are members of the United States and British militaries.

Although the de jure currency is GBP (Pound Sterling), the de facto currency is USD (US Dollar) because the US military's deployment considerably outnumbers the British military's deployment.

Sure is the only network operating in the territory.
