Regional and global plans for extreme locations
esimbloom has no plan listed for French Southern Territories right now. Check the regional and global plans linked below — each plan page lists the countries it covers — or a nearby destination.
Each plan is data-only: you can use maps, messaging apps, email, and web browsers, but there is no local phone number for traditional voice calls or SMS. The eSIM connects over the local mobile network at whatever speed it and your device support. Check the regional and global plan pages on esimbloom to compare data allowances, validity periods, and country lists before purchasing.
How to activate your eSIM before travelling
Your device must support eSIM technology and be carrier-unlocked. After you complete your purchase, esimbloom emails a QR code within minutes. Scan the QR code from your phone's eSIM or cellular settings menu while you still have a Wi-Fi or mobile connection, then label the new plan so you can identify it later. Do not enable or activate the data line yet.
Wait until you arrive in the French Southern Territories, then turn on the esimbloom data line in your settings and turn off your home SIM's data roaming. Your validity period starts the moment the eSIM first connects to a network, so installing early but activating on arrival ensures you do not waste days of your allowance while still at home.
Connectivity in one of the world's remotest territories
The French Southern Territories comprise several island groups scattered across the southern Indian Ocean, including Kerguelen, Crozet, Amsterdam, and Saint-Paul. Permanent population is limited to rotating scientific and military staff at a handful of research stations. Mobile coverage exists only at or very near these staffed bases, primarily on Kerguelen at Port-aux-Français and on Crozet at Alfred Faure station. Elsewhere across the islands, and throughout the vast marine reserve, there is no terrestrial mobile network.
If you are travelling as a researcher, support personnel, or rare expedition visitor, expect connectivity to be intermittent and confined to the immediate vicinity of the station. Satellite communication remains the primary link for most activities. Budget your data for essential communication and light map caching. Download offline maps, translation files, and any reference documents before departure, because reliable internet access will be unavailable for the majority of your time in the territory.
Frequently asked questions
Will I have mobile data across the entire French Southern Territories?
No. Mobile coverage exists only at staffed research stations, mainly Port-aux-Français on Kerguelen and Alfred Faure on Crozet. The rest of the territory has no terrestrial mobile network. Satellite links are used for most communication.
When does my eSIM plan validity period start?
The validity period begins the moment your eSIM first connects to a network. Install the QR code while you have internet at home, but wait to enable the data line until you reach the French Southern Territories.
Can I make phone calls or send SMS with an esimbloom eSIM?
No. esimbloom plans are data-only and do not include a local phone number. Use internet-based apps such as WhatsApp, Signal, or FaceTime for calls and messages over your data connection.
Do I need to turn off my home SIM when I arrive?
Turn off data roaming on your home SIM to avoid roaming charges. You can leave the home SIM active for incoming calls and texts if your phone supports dual SIM, but route all data through the esimbloom eSIM.
