The British Indian Ocean Territory, centred on Diego Garcia atoll, has no public civilian mobile network infrastructure. Access to the territory is strictly controlled and limited to authorised military and government personnel, contracted workers, and specific maritime visitors. Any connectivity available within the territory relies on military or government communication systems rather than commercial mobile networks. A MobiSIM eSIM for the British Indian Ocean Territory provides a digital data option where supported network coverage exists for eligible travellers, but standard mobile connectivity is not available to the general public in this territory. All essential documents, maps, and communication tools should be prepared and stored offline before departure from your origin.
