常见问题解答

eSIM（嵌入式 SIM 卡）是直接安装在手机芯片上的数字配置文件，无需插入实体塑料卡。您只需通过网络下载并激活即可完成连网，免去前往营业厅或等待快递的烦恼。同时，您的原手机卡可保持正常激活状态，实现出国上网与原卡接收短信两不误。

Most travel plans are data-only. For destinations that support voice and text, select 数据流量 + 语音通话 + 短信 plans in the plan filter.

Hotspot availability depends on the specific plan and network rules in that destination. Check the plan details before checkout.

Yes. Most modern dual-SIM devices let you run an eSIM for travel data while keeping your physical SIM active for calls and texts. You can switch the default data line between SIMs in your device settings at any time.

Storage varies by device. Most iPhones and many Android phones can hold 8–20 eSIM profiles, though typically only one or two can be active simultaneously. You can switch between stored profiles in Settings without deleting them, making it convenient to manage eSIMs across multiple trips.

订单完成交付后，二维码将发送至您的邮箱并同步至 MollySIM 账户。安装方法：进入“设置 > 蜂窝网络（或移动数据） > 添加 eSIM”，选择“扫描二维码”并对准屏幕或打印件扫描，配置将自动完成安装。请确保安装时设备已连接至稳定的 Wi-Fi 网络。

2018 年后发布的大多数主流旗舰智能手机均支持 eSIM，包括 iPhone XS/XR 及后续机型、三星 Galaxy S20 及后续机型、谷歌 Pixel 3 及后续机型。您可在“设置 > 通用 > 关于本机”（iPhone）或“设置 > 关于手机”（Android）中检查设备兼容性。此外，设备必须为无锁机（Unlocked）方可激活第三方 eSIM 套餐。

在有稳定Wi-Fi时安装，最好在出发前。抵达后根据您的旅行时间和套餐有效期激活线路。

No. A purchased profile is generally bound to one device during activation. If you need another device, purchase an additional eSIM.

No. Carrier-locked devices cannot activate eSIM profiles from third-party providers. Contact your carrier to request an unlock — many unlock devices automatically after a contract period, or upon request. Confirm your device is fully unlocked before purchasing a MollySIM plan.

Try these steps: clean your camera lens, increase the screen brightness on the device displaying the QR code, or scan in better lighting. Most orders also include a manual activation code — select Enter Details Manually in your cellular settings as an alternative. If the issue persists, contact support with your order ID before deleting any eSIM profile.

Validity start rules depend on the provider. Most plans begin counting down from your first data connection in the destination country — not from the date of purchase or installation. A small number of providers start validity at installation time. Always check the plan details page before buying to confirm the exact validity start rule for that plan.

当高速流量额度耗尽后，网络将暂停或根据套餐规则降速提供服务。您可以登录账户随时为同一目的地再次购买新套餐，系统将快速复用您的信息，即买即用。

Yes, regional plans are designed for multi-country trips inside supported areas. Coverage lists vary by plan and should be checked before buying.

It depends on the plan. Some plans throttle data to a reduced speed (typically 128–512 kbps) after the full quota is used rather than cutting off entirely, while others stop data completely. Check the plan details page for the after-quota policy — it will indicate whether data stops or continues at reduced speed.

购买后不支持暂停或延长套餐有效期，因为条款是由底层运营商设定的。如果你预计行程较长或有中断，请从一开始选择有效期较长的套餐，或者购买第二个套餐来覆盖所需的剩余天数。

我们支持通过 Stripe 和 PayPal 使用各大信用卡与借记卡付款。根据您的设备与浏览器，结账页面还将自动提供 Apple Pay 和 Google Pay 便捷支付。所有交易均由合规支付通道加密处理，MollySIM 服务器不会留存您的银行卡敏感信息。

我们提供灵活的退款保障：根据《退款政策》，对于尚未激活且未使用的套餐，可以在有效期内申请全额退款。一旦套餐被激活或已开始计算有效期，除可证实的网络技术故障外，暂不开放退款。提交退款申请时，请附上您的订单号及原因。

Go to My Orders to track payment and eSIM fulfillment status. Updates are synced as provider events arrive.

首先，请检查您的垃圾邮件或广告邮件文件夹以查找确认邮件。然后登录您的账户并前往“我的订单”——您的二维码和eSIM详情即使邮件未送达也在此处可用。如果您的订单显示待处理超过30分钟，请联系客服并提供您的订单ID和支付确认。

Yes. Add plans for different destinations to your cart and complete a single checkout. Each plan appears as a separate order in My Orders with its own QR code and validity period. Install each eSIM before the relevant trip to avoid starting the validity countdown early.

Work through these steps: confirm your destination is covered by the plan; in Settings > Cellular, ensure the eSIM line is enabled and selected as the active data line; toggle airplane mode on and off to force a network refresh; try selecting a network manually in Network Selection. If the issue continues, restart your device and contact support with your order ID and device model.

Activation failures can happen if the device is not fully carrier-unlocked, if the QR code was previously used on a different device, or due to a temporary provider issue. Restart your device and confirm your cellular settings are correct. Do not delete the profile before contacting support — send a screenshot of the error along with your order ID so we can assist.

网速慢可能是由于你所在区域的网络拥堵、漫游到较弱的合作商网络，或者套餐进入了公平使用限速状态。请在“设置 > 蜂窝网络”中检查你的剩余流量并查看套餐的限速政策。移动到其他位置可能会有帮助；如果网速依然非常慢，请携带订单号联系客服。

In most cases, eSIM profiles cannot be transferred once activated, as the profile is bound to the device at activation. If the eSIM was never activated, contact support before removing it from your old phone — some providers allow a limited number of re-downloads. For future trips, purchase a new eSIM plan once your new device is set up and confirmed as carrier-unlocked.
