About French Guiana eSIM
eSIM French Guiana: 5G/4G for Cayenne & the Kourou Space Centre
Welcome to French Guiana, a unique department of France nestled in South America. Whether you are in Cayenne for business, or in Kourou for a mission at the Guiana Space Centre (Centre Spatial Guyanais), a high-speed, reliable data connection is non-negotiable.
Stay connected in this high-tech jungle with EastESIM's French Guiana eSIM plans, starting at just $2.00. Choose from 7 limited and 14 unlimited plans.
CRITICAL: Avoid the "South America" Roaming Trap
IMPORTANT WARNING: While technically part of France, French Guiana is in South America. For most non-EU carriers (from the US, UK, Canada, Asia, etc.), this territory is NOT included in any "European" roaming plan.
Your home carrier will charge you astronomical "Rest of World" or "South America" roaming fees, often per-megabyte. An eSIM for French Guiana is the only smart, cost-effective way to get data. Get connected the moment you land at Cayenne , Félix Eboué Airport (CAY).
Why EastESIM is Essential for Your Trip to French Guiana
- Instant (CAY) Airport Connection: Get online the moment you land at (CAY) Airport. This is critical for coordinating transport or contacting your team in Kourou or Cayenne.
- Massive Cost Savings: Our plans start at $2.00 This is a fraction of what you would pay for just a few megabytes of high-cost roaming.
- Keep Your Home Number: Your eSIM handles the data, so your primary SIM (and your WhatsApp number) remains active for important calls and texts.
- Premium 5G/4G Speed: As this is an EU territory, the infrastructure is strong. Connect to top-tier 5G/4G networks (like Orange Caraïbe) perfect for business needs.

Frequently Asked Questions
Most flagship smartphones released since late 2018 or early 2019 are fully compatible with EastESIM technology, making your travel connectivity seamless. This includes popular models like the iPhone XS and all newer iPhones, Google Pixel 3 and subsequent Pixel models, and the Samsung Galaxy S20 series and its successors. Beyond phones, an increasing number of tablets and smartwatches also support eSIM. The quickest way to confirm compatibility for your specific device is to check its settings under 'Mobile Data' or 'SIM Card Manager,' or consult your device manufacturer's official website.
Almost every flagship smartphone model released since 2019 is equipped with eSIM capability, making it an ideal solution for international travel with EastESIM. This includes a wide range of devices such as the iPhone XS, iPhone 11, iPhone 12, iPhone 13, iPhone 14, and iPhone 15 series, as well as the Google Pixel 3, Pixel 4, Pixel 5, Pixel 6, Pixel 7, and Pixel 8 series. Many Samsung Galaxy S20, S21, S22, S23, and S24 models also support eSIM, along with a growing list of mid-range and other brand devices. This widespread compatibility ensures a smooth connection to our Asian networks.
You need to be very cautious about roaming charges when traveling between Mainland China and Hong Kong, or even Macau. Despite their proximity, these are distinct administrative regions with different telecom regulations and often separate network agreements. While some mainland Chinese carriers might offer specific roaming packages for Hong Kong, 'free roaming' is generally not the standard. Using your mainland SIM in Hong Kong without a dedicated add-on will likely incur significant roaming fees. An EastESIM plan specifically for Hong Kong, or a multi-country Asia plan, offers predictable and affordable data, ensuring you stay connected without unexpected costs.
A single-country EastESIM plan, like one specifically for Vietnam, is valid only within that country's borders. If you're embarking on an overland adventure from Ho Chi Minh City to Phnom Penh, or from Hanoi into Laos, your Vietnam-specific connection will cease at the border. For seamless travel across nations like Vietnam, Cambodia, and Laos, we highly recommend one of our multi-country Asia plans. These packages are designed for regional exploration, ensuring you remain connected as you cross borders without needing to buy a new eSIM for each country.
While EastESIM strives for extensive coverage, internet access in extremely remote Asian regions like the Cardamom Mountains of Cambodia or parts of rural Myanmar can be limited. You'll enjoy excellent 4G/LTE coverage in major cities such as Phnom Penh and Siem Reap, and even in popular coastal towns like Sihanoukville. However, as you venture into deep jungles, mountainous regions, or very sparsely populated areas, signal strength may decrease, sometimes to 3G or even become intermittent. We partner with local leaders like Smart Axiata to maximize reach, but setting realistic expectations for truly off-grid locations is wise.
To provide you with the best connectivity across the diverse islands of the Philippines, your EastESIM will typically connect to the nation's leading mobile networks. These usually include major providers like Globe Telecom or Smart Communications. These partnerships ensure you receive robust 4G/LTE (and often 5G) coverage in bustling cities like Manila and Cebu, as well as in popular tourist destinations such as Boracay and Palawan. Our focus on top-tier local carriers means you can rely on fast, stable internet for navigation, communication, and sharing your adventures.
For mobility and consistent performance, EastESIM mobile data is generally more reliable than hotel Wi-Fi, especially when exploring. While larger hotels in cities like Bangkok or Seoul may offer decent Wi-Fi, it's often shared, slower, and certainly won't help you when you're out and about. An EastESIM provides a private, secure, and stable connection, crucial for using navigation apps like Google Maps in a new city, hailing a ride via Grab, or translating on the fly. It's your personal internet lifeline, unaffected by hotel network congestion or power fluctuations.
To ensure a smooth journey with EastESIM, it's vital to verify your phone's eSIM compatibility. While many newer models from brands like Apple (iPhone XR and later), Samsung (Galaxy S20 and newer), and Google Pixel (Pixel 3a and newer) support eSIM, some regional variations exist. The simplest way is to check our dedicated 'eSIM Compatible Devices' list on the EastESIM website. This resource provides a comprehensive and up-to-date guide to ensure your device is ready for seamless connectivity across Asia.
Yes, your EastESIM will provide superb internet coverage at Gardens by the Bay in Singapore. You'll enjoy strong 4G/5G signal across the entire park, from the awe-inspiring Supertrees to the cool environments of the Cloud Forest and Flower Dome. This means you can effortlessly upload stunning photos, stream the nightly light show, or use digital guides to learn more about the diverse plant collections. EastESIM ensures you stay connected while marveling at one of Asia's most futuristic natural attractions.
Yes, EastESIM provides reliable signal throughout the magnificent Angkor Wat complex and surrounding temples near Siem Reap. You'll be able to capture and instantly share your awe-inspiring moments from Angkor Thom, Bayon, and, of course, the iconic Angkor Wat itself. While exploring these ancient wonders, our robust connectivity ensures you can access online guides, look up historical facts, or simply share your adventure with loved ones. Stay connected even amidst Cambodia's profound history.
Absolutely, your EastESIM will provide excellent data for using popular ride-sharing apps in Phnom Penh. Services like Grab and PassApp are widely used and highly recommended for convenient travel around the city. With a strong EastESIM connection, you can easily book tuk-tuks or cars to visit attractions like the Royal Palace, the Silver Pagoda, or the Central Market. Our reliable service ensures you're always connected, making your Cambodian urban exploration smooth and hassle-free.
You'll generally find reliable signal in the main tourist areas and closer to the port cities like Ha Long City or Cat Ba Island. As your boat ventures deeper into the iconic limestone karsts of Ha Long Bay, especially in more secluded coves or far from the mainland, the connection might become intermittent or drop. However, EastESIM partners with Vietnam's leading carriers, like Viettel and Mobifone, to maximize your chances of connectivity even in these stunning, more remote parts of the bay. Enjoy the views, and connect when possible!
