越南 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.

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.

不，互联网是开放的！这是一个常见的误解。与中国不同，越南没有拥有“防火墙”。您可以自由访问 Google、Facebook、Instagram、WhatsApp、TikTok 以及所有您喜爱的应用程序，无需 VPN。我们的 eSIM 可让您不受限制地高速访问开放互联网。 

 此特定计划仅在越南境内有效。这是背包客最关心的问题。如果您在“香蕉煎饼小道”上并越过边境进入柬埔寨或老挝，您的连接将停止。对于无缝的多国旅程，我们强烈推荐我们的亚洲区域 eSIM，它通过一个计划覆盖越南、柬埔寨、泰国和老挝。 

是的，但情况有所不同。您将在所有城市（河内、胡志明市、岘港）和城镇拥有出色的4G/LTE覆盖范围。在下龙湾游轮上，靠近海岸时信号很强，但在深入石灰岩喀斯特地区时信号可能会间歇性或缓慢。对于沙巴和河江环路等山区，您在城镇中信号良好，但在偏远山口行驶时应注意信号盲区。 

 为了在这个狭长的国家/地区为您提供最佳的覆盖范围，我们的 eSIM 会连接到顶级提供商，通常是 Viettel 或 Vinaphone。 Viettel 被广泛认为是覆盖范围最广的最佳网络（如军事网络），尤其是在农村和山区，可确保您在其他网络出现故障时保持连接。 

是的，绝对。 Grab 是越南必不可少的“超级应用”，用于预订乘车（汽车和摩托车）和送餐。我们的 eSIM 提供快速、低延迟的数据，这对于从机场（河内 - NOI 或胡志明 - SGN）订购 Grab、实时跟踪您的司机以及使用 Google 地图在混乱的街道中导航至关重要。 

 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。 

在河内和胡志明市之间的大部分沿海旅程中，您将有 4G 信号，但预计在隧道或海云山口附近的偏远路段连接会中断。 

是的。芹苴和 Cai Rang 水上市场的信号覆盖范围很广，您可以立即分享船贩的照片。 

一般来说，在天堂洞或峰牙洞的游客中心和入口处会有信号，但一旦进入地下深处，信号自然就消失了。 

是的。适合步行的会安古镇的覆盖范围非常广，这对于与当地裁缝一起使用翻译应用程序或寻找最佳的 banh mi 地点至关重要。
