Republic of the Congo 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.

This is a vital distinction for your travel plans. Each EastESIM product is specifically designed for certain countries or regions. For instance, a plan labeled 'Philippines' will work exclusively within the Philippines, connecting to networks like Globe or Smart. It will not work in Indonesia, which requires a separate plan tailored for Indonesian networks such as Telkomsel or XL Axiata. Always double-check the specific country or regional coverage listed on your chosen EastESIM plan to ensure it matches your itinerary.

It depends on the specific EastESIM plan you choose. If you've selected a single-country plan, for example, for Singapore, it will only function there, connecting to networks like Singtel. Once you cross into Malaysia, it will cease to work. For travelers exploring multiple destinations, EastESIM offers fantastic multi-country Asia Regional Plans that explicitly cover several nations, such as a plan for 'Southeast Asia' that includes both Singapore and Malaysia. Always verify the listed countries on your plan's description.

EastESIM strives to provide the widest possible coverage, but expectations should be set for more remote Asian locations. You'll enjoy excellent 4G/LTE coverage in major urban centers like Denpasar (Bali) or Hanoi, connecting to strong local carriers such as Telkomsel or Viettel. However, as you venture into very rural or mountainous regions, particularly in countries like Laos or the more remote islands of the Philippines, coverage can become spotty or drop to 3G. We recommend downloading offline maps for deep rural exploration.

To ensure you get the best possible connection while exploring Thailand, EastESIM partners with the country's premier mobile providers. Your eSIM will typically connect to networks like AIS or TrueMove H. These carriers offer extensive 4G/5G coverage across major cities like Bangkok and Chiang Mai, popular tourist islands such as Phuket and Koh Samui, and even many less-traveled areas. This ensures you stay connected for navigation, communication, and sharing your adventures.

No, and this is one of EastESIM's biggest advantages for travelers in Asia! When you buy a physical local SIM card at airports in countries like Vietnam or Indonesia, you often face a mandatory and sometimes lengthy passport registration process. Our EastESIM is a roaming data plan, meaning it bypasses all this local bureaucracy. You can activate your eSIM digitally before you even land, saving you time and hassle at the airport and letting you start your adventure in Hanoi or Bali connected immediately.

Yes, EastESIM generally offers good coverage across Halong Bay, especially in the more populated areas and near the main cruise routes. You should be able to share those breathtaking photos of limestone karsts and emerald waters directly from your boat. While signal might occasionally fluctuate in more secluded coves or deeper waters, our robust partnerships with Vietnamese carriers ensure you stay connected for most of your unforgettable journey through this UNESCO World Heritage site.

Connectivity within Komodo National Park, while generally available, can be somewhat limited, especially on smaller islands or during boat transfers between them. You will likely find signal around the main tourist hubs like Labuan Bajo on Flores and at popular spots such as Komodo Island or Rinca Island. However, when you're trekking to see the dragons or snorkeling in remote bays, expect intermittent service. We recommend enjoying the pristine nature and perhaps going offline for a bit!

Whether you're participating in video conferences, sending large files, or managing emails from a café in District 1, our reliable connection will keep you productive.
