Regional and global plans for remote territory access
esimbloom has no plan listed for the British Indian Ocean Territory right now. Check the regional and global plans linked below — each plan page lists the countries it covers — or a nearby destination.
Browse the regional and global plan catalogue to find the coverage area, data allowance, and validity period that match your itinerary. All plans use the local mobile network at whatever speed it and your device support. Once you complete your purchase, the QR code arrives by email and remains valid until you activate it on arrival.
Installing and activating your eSIM
Before you leave home, confirm that your phone is unlocked and eSIM-compatible, then install the eSIM by scanning the QR code in your email. The profile will sit dormant on your device until you choose to activate it. Most travellers add the eSIM as a secondary data line and keep their primary SIM for calls and messages.
Activate the plan when you reach the territory and need mobile data. Go to your phone's cellular settings, select the esimbloom eSIM as your data line, and enable data roaming for that line only. Connection is typically immediate. If the eSIM does not register within a few minutes, toggle airplane mode or restart your device.
Connectivity in an isolated archipelago
The British Indian Ocean Territory is one of the world's most isolated locations, comprising the Chagos Archipelago in the central Indian Ocean. Civilian access is extremely limited, and connectivity infrastructure is sparse. If you are travelling to Diego Garcia or another approved site, expect coverage to be concentrated around military and administrative facilities rather than across the atolls.
Because the territory has no permanent civilian population, commercial mobile networks are minimal. Data usage will be light by necessity: email, messaging, and essential navigation rather than streaming or large downloads. Latency may be higher than on continental networks, and fallback on the local mobile network is possible. Plan for intermittent connectivity and download any critical maps, documents, or contact details before arrival.
Frequently asked questions
Will my eSIM work on Diego Garcia?
Coverage depends on the underlying network included in your regional or global plan and on local infrastructure. Diego Garcia has limited connectivity concentrated around official facilities. Confirm your plan includes the British Indian Ocean Territory before purchasing.
Can I use the eSIM as soon as I buy it?
The eSIM can be installed immediately after purchase, but it should be activated only when you arrive and need mobile data. Validity periods begin at activation, so installing early at home lets you test the setup without consuming your allowance.
Do I get a local phone number with my eSIM?
No. All esimbloom plans are data-only. You will have mobile internet for messaging apps, email, and browsing, but no local number for traditional voice calls or SMS. Use internet-based services for communication instead.
What happens if I run out of data while I'm there?
You can purchase a top-up or a new plan from esimbloom and install the additional eSIM profile on your device. Because the territory is so remote, arrange connectivity before your data runs out to avoid being offline in an isolated location.
