Greenland eSIM

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.

No. An eSIM can be installed only once, and it locks to the first device it is installed on. It cannot be moved to another phone, re-scanned, or reinstalled afterward, and it is non-refundable once installed. Please install your eSIM on the device you plan to keep using. If you are switching devices and need help, contact our support team.

No, this is a common misconception and a significant roaming trap for travelers! While Macao and Hong Kong are geographically close to mainland China, they are distinct administrative regions. Your 'Roam Like at Home' (RLAH) plan from an EU or Australian carrier typically does not extend to these areas. Even if your plan covers mainland China, it's highly unlikely to include Macao or Hong Kong. Relying on your home SIM here will almost certainly lead to exorbitant international roaming charges. An EastESIM offers a far more predictable and affordable solution.

EastESIM strives to provide the best possible coverage, but it's important to set realistic expectations for very remote areas in developing nations. You will have excellent 4G/LTE coverage in all major towns and tourist hubs such as Vientiane, Luang Prabang, Phnom Penh, and Siem Reap. However, if you venture deep into extremely rural or mountainous regions, particularly along less traveled routes in Laos or Cambodia, signal availability might become sporadic or limited to 2G/EDGE. We partner with the strongest local networks like Unitel in Laos and Smart Axiata in Cambodia to maximize your connectivity.

To ensure you experience the best possible speed and coverage throughout your travels in Vietnam, EastESIM primarily connects to Viettel. Viettel is widely recognized as Vietnam’s largest and most extensive mobile network operator, offering robust 4G and growing 5G coverage across the country. This partnership ensures reliable connectivity whether you're exploring the vibrant streets of Hanoi, cruising through Ha Long Bay, or relaxing on the beaches of Da Nang. You can count on a strong signal for navigation, communication, and sharing your adventures.

Yes, EastESIM is an ideal connectivity solution for cruise passengers making port calls in Asia! Your ship's satellite Wi-Fi can be incredibly expensive and often unreliable. The moment your vessel docks at a port like Swettenham Pier Cruise Terminal in Penang, Malaysia, or the Laem Chabang Port for Bangkok, your EastESIM will automatically connect to the local 4G/5G network. This allows you to immediately access local maps, book ground transportation, or share your experiences in real-time as you explore destinations like George Town or Singapore.

While EastESIM provides extensive coverage through strong local partnerships, signal availability can vary in extremely remote or natural environments. At popular viewpoints near active volcanoes like Mount Bromo in East Java or within the main tourist areas of Bali's rice paddies (e.g., around Ubud), you will generally have a good signal. However, on multi-day, deep-wilderness treks or in very isolated valleys, you should anticipate intermittent or no signal. We leverage networks like Telkomsel in Indonesia, known for its wide reach, but some truly off-grid locations remain challenging for any provider.

With EastESIM, you'll generally experience strong signal when docked at the ferry terminals in both Hong Kong and Macau. However, as the ferry crosses the open waters of the Pearl River Estuary, the signal might become intermittent or drop entirely for periods. While some ferries offer onboard Wi-Fi (often for a fee), relying on your EastESIM for continuous data during the entire journey might be challenging. It's a good time to enjoy the views or catch up on offline entertainment!

Yes, EastESIM works flawlessly at Incheon International Airport (ICN) in South Korea. As one of the world's best-connected airports, you'll have excellent 5G/4G LTE coverage the moment you land. This allows you to immediately connect with family, arrange transportation, or look up last-minute travel details. Our partnerships with leading Korean carriers like SK Telecom and KT ensure a smooth, high-speed connection from the very start of your adventure.

While deep wilderness areas on high-altitude trekking routes in Nepal (like parts of the Everest Base Camp trek or Annapurna Circuit) will have limited to no signal, having EastESIM data is crucial in more accessible areas. It's vital for coordinating with your trekking guide, checking weather forecasts in towns like Pokhara or Lukla, and for safety communications at trailheads. Even in remote tea houses, you might occasionally catch a signal, making it valuable for essential communication.

Absolutely! In major Asian cities like Seoul, Tokyo, Singapore, and Kuala Lumpur, EastESIM provides excellent 4G and often 5G speeds, making it more than sufficient for remote work. You can comfortably handle video calls, large file transfers, and cloud-based applications. Even in bustling cities like Bangkok or Ho Chi Minh City, our strong partnerships with local carriers ensure reliable and fast internet, allowing you to stay productive while enjoying your travels across Asia.
