Decision guide

Choosing the right service for calling British Indian Ocean Territory

When selecting an international calling service for British Indian Ocean Territory, four factors separate the durable providers from the noise. Look for a proven track record on each.

Coverage

Zone 2 routes are fragmented — confirm direct in-country termination to Diego Garcia, not regional hub routing.

Reliability

African routes degrade on cable outages — require redundant paths and a published failover RTO for British Indian Ocean Territory.

Customer support

Confirm coverage for Indian/Chagos hours — a Diego Garcia route issue at 09:00 needs a human response, not a next-day ticket.

Transparent pricing

Zone 2 landline and mobile rates can differ 5× — demand separate +246 landline and mobile rate sheets.
