蒙古国 eSIM

Most flagship smartphones released since 2018-2019 support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 series and newer. Tablets, smartwatches and an increasing number of laptops also support eSIM. The fastest way to verify your specific device is to check Settings , if you see "Add eSIM" or "Add cellular plan" as an option, you're compatible.

eSIM compatibility is now standard across the high-end smartphone market and rapidly spreading into mid-range devices. Cellesim works with any unlocked, eSIM-capable device , no special configuration needed beyond scanning the QR code we send you.

How to verify eSIM support on your device

1. iPhone: Settings → Cellular → look for "Add eSIM" or "Add Cellular Plan". You can also dial *#06# , if you see an "EID" (32-digit number), your phone has eSIM hardware.
2. Android: Settings → Connections (or Network & Internet) → SIM Cards → look for "Download a SIM instead" or "Add eSIM".
3. EID check: most eSIM-capable Android phones show EID in Settings → About Phone → Status.

Tip: Even if your phone supports eSIM hardware, it must be unlocked (not carrier-locked) to use third-party eSIMs like Cellesim. Most phones bought outright are unlocked; phones from carrier instalment plans may require unlocking after the contract is paid off.

Almost every flagship smartphone released since 2019 supports eSIM, making it ideal for international travel. Compatible models include iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus a growing list of mid-range devices. If your phone has Settings → Cellular → "Add eSIM", you're ready to use a Cellesim plan abroad.

Travellers benefit most from eSIM because it eliminates the airport SIM-card queue, removes the need to swap your home SIM out, and lets you keep your usual phone number active for SMS verification. A Cellesim travel eSIM activates the moment you land , no shop visit required.

3. iOS version: iOS 12.1 or newer for full eSIM support.
4. Android version: Android 9 or newer typically supports eSIM, though it depends on the manufacturer.
5. Region-specific variants: some Samsung models sold in Hong Kong or China are dual physical SIM with no eSIM , verify your specific model number.

Tip: if your current phone doesn't support eSIM but you travel often, an unlocked, mid-range eSIM-capable phone (e.g., Pixel 7a, iPhone SE 3, Samsung Galaxy A55) makes an excellent secondary travel device , pair it with a Cellesim plan and you have a full mobile internet kit for any destination.

这取决于位置。在乌兰巴托和主要省级中心（Aimag中心），您将拥有出色的4G/LTE速度。然而，戈壁滩和广阔的草原却极为偏远。虽然我们的 eSIM 连接到最好的可用信号塔，但在沙漠深处（如 Khongor 沙丘），信号可能会断断续续或不存在。大多数蒙古包游客营地都位于信号塔附近，但我们强烈建议在离开城市之前下载离线地图。 

 在蒙古，可靠性就是一切。我们的 eSIM 连接到该国领先的提供商，通常是 Unitel 或 Mobicom。这些运营商在全国范围内拥有最广泛的基础设施，无论您是参加巴彦乌列盖的雄鹰节还是参观库苏古尔湖，都可以为您提供最好的保持联系的机会。 

 此特定计划仅在蒙古境内有效。横贯蒙古铁路是连接俄罗斯、蒙古和中国的热门旅程。一旦火车越过边境进入俄罗斯（西伯利亚）或中国（内蒙古），您的连接将停止。对于这次传奇的火车之旅，我们强烈建议您查看我们的亚洲区域或全球 eSIM 计划，以便在所有三个国家/地区保持联系。 

是的。GPS对于在蒙古无标记的土路上行驶至关重要。我们的 eSIM 可让您使用 Google 地图 或 Maps.me。虽然您可能会在目的地之间失去信号，但当您到达地势较高的地方或定居点时保持活跃的连接对于安全以及与旅行社或租赁机构的沟通至关重要。 

是的。大多数传统的蒙古包营地没有 Wi-Fi，或者速度很慢。我们的 eSIM 完全支持个人热点（网络共享）。这意味着您可以将手机变成路由器，并与笔记本电脑或蒙古包内的朋友共享您的数据，上传您的星夜照片或在睡觉前查看电子邮件。 

 大多数现代手机都可以，但您必须在此处查看我们的具体列表：eSIM兼容设备，以便在购买前 100% 确定。 

不，优步不在蒙古运营。您需要可靠的数据来使用 UBCab（当地最受欢迎的出租车应用程序）安全地游览乌兰巴托并避免与司机的语言障碍。 

通常，您在卡特加尔和汉赫的门户村庄会有很强的信号，让您可以分享“亚洲蓝色珍珠”的照片，但如果您冒险进入水域或偏远的海岸，覆盖范围会显着下降。 

是的。位于 Tsonjin Boldog 的巨大成吉思汗马术雕像的可靠覆盖，让您可以从马头上的观景台现场直播全景。 

绝对地。如果您在 7 月来参加那达慕大会，可靠的数据对于查看国家体育场或 Khui Doloon Khudag 摔跤、射箭和赛马活动的实时时间表至关重要。
