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.

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.

重要提示：此特定计划仅在卢森堡境内有效。由于该国很小，许多游客会前往特里尔（德国）、梅斯（法国）或巴斯托涅（比利时）进行一日游。请注意，您的连接将在越过边界后立即停止。如果您的行程涉及访问邻国，我们强烈推荐我们的欧洲区域 eSIM，以确保整个“比荷卢经济联盟”和边境地区的无缝连接，而无需交换计划。 

 虽然卢森堡提供免费公共交通（火车、电车、公共汽车），但依赖公共 Wi-Fi 可能会令人沮丧且不安全。公共网络通常速度缓慢、有时间限制，或者使您的设备容易受到黑客攻击。 Cellesim eSIM 提供私密、安全和高速的连接，如果您在前往基希贝格金融区的途中访问手机银行或企业电子邮件，这一点至关重要。 

 为了符合大公国的高标准，我们的 eSIM 卡连接到该国的优质网络，通常是 POST Luxembourg 或 Tango。无论您是在卢森堡市的格伦德深谷、在米勒塔尔步道（小瑞士）徒步旅行，还是参观北部的维安登城堡，这都能确保您获得最佳的4G/5G覆盖范围。 

这取决于。卢森堡属于欧盟。然而，自英国脱欧以来，许多英国提供商重新征收漫游费。对于来自美国、瑞士或亚洲的旅行者来说，漫游费绝对不是免费的，而且可能非常昂贵。使用 Cellesim Luxembourg eSIM 是锁定较低的固定数据价格的最明智方法，而且不会面临来自本地运营商的意外账单的风险。 

当然。卢森堡是银行业和欧盟机构的全球中心。我们的 eSIM 提供适合专业用途的高速、低延迟数据。您可以自信地主持 Zoom 或 Teams 通话、下载大型附件，并在市中心的酒店或咖啡馆保持工作效率，不受干扰。 

 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。 

是的。虽然公共交通在全国范围内免费，但您需要有效的移动数据才能使用 Mobiliteit.lu 应用程序了解实时时刻表并找到卢森堡市正确的巴士或火车站台。 

通常，在步道起点和埃希特纳赫等村庄会有信号，但在穆勒塔尔地区的深岩石峡谷和茂密森林中，信号覆盖范围往往会下降。 

您将在入口处和全景视点处获得良好的信号，但当您深入炮台的厚岩石隧道和防御廊道时，连接可能会丢失。 

是的。维安登镇和乘坐缆车期间的信号覆盖可靠，让您可以分享我们河上城堡的壮观照片。
