冰岛 eSIM

WorldESIM technology is supported by a wide and growing range of modern devices, making global connectivity more accessible than ever. Most flagship smartphones released from late 2018 onwards are eSIM-compatible, including iPhone XS and newer models, Google Pixel 3 and its successors, and the Samsung Galaxy S20 series and later. Beyond smartphones, many tablets, smartwatches, and even some laptops now incorporate eSIM capabilities. The quickest way to confirm your device's compatibility is to check its settings for an 'Add eSIM' or 'Add Cellular Plan' option, or consult your device manufacturer's specifications.

For seamless international travel, WorldESIM is supported by almost every flagship smartphone released since 2019, making it an excellent choice for digital nomads and global explorers. Key compatible models include the iPhone XS, iPhone XR, and all subsequent iPhone generations; Google Pixel 3 and all newer Pixel models; and the Samsung Galaxy S20 series, S21, S22, S23, and S24 lineups, along with many of their 'FE' and 'Flip/Fold' variants. Additionally, a growing number of mid-range devices from various manufacturers are now incorporating eSIM functionality, expanding accessibility for WorldESIM users worldwide.

不可以。eSIM只能安装一次，并锁定到首次安装的设备上。之后无法移动到其他手机、重新扫描或重新安装，一旦安装便不可退款。请将您的eSIM安装到您计划继续使用的设备上。如果您正在更换设备并需要帮助，请联系我们的支持团队。

Yes. With WorldESIM you top up the eSIM you already installed. You do not scan a new QR code, you do not install a second profile, and your phone number setup does not change.

Open the WorldESIM app or your account page, pick a top-up for the eSIM you are using, and the data is added to the same line. The validity period is extended at the same time, so a 7-day plan topped up on day 5 keeps running instead of expiring.

This matters most when you are already travelling: running out of data usually means you have no connection to buy more with. Because the top-up lands on the existing profile, it works as soon as it is processed, without Wi-Fi and without reinstalling anything.

WorldESIM includes a free VPN with every active eSIM. It is not an add-on, a trial, or a paid upgrade: as long as you have an eSIM plan that is still valid, the VPN is available at no extra charge.

This is unusual in the travel eSIM market. Most providers sell data only, and you buy a VPN separately from a VPN company. A few bundle a paid VPN subscription. With WorldESIM the data plan and the VPN come from the same purchase.

It matters because mobile data abroad does not solve everything. Public Wi-Fi in airports and hotels is unencrypted, some services are restricted depending on the country you are connected from, and banking apps behave differently on foreign networks. The VPN covers that part.

Almost always, yes — usually by an order of magnitude. Standard carrier roaming outside your home region is commonly billed per megabyte or as a daily pass of 10-15 USD. A travel eSIM is a prepaid data plan bought at local wholesale rates.

A concrete comparison: a 5 GB / 30-day plan for a single country averages about 28 USD across our catalogue. A daily roaming pass at 10 USD reaches that after three days, and keeps charging.

The exception is regional roaming that your carrier already includes for free — EU-to-EU roaming for EU customers, for example. If your plan covers the country you are visiting at no extra cost, use it. Everywhere else, prepaid data is cheaper.

比大多数攻略里说的要少。根据我们对 278 位旅行 eSIM 用户的统计，每日流量消耗的中位数是 96 MB。平均值为 158 MB，即使是流量消耗排在前 10% 的重度用户，每天也用不到 350 MB。

也就是说，为期一周的旅行：

• 1 GB 足够一般旅客使用——查地图、发消息、偶尔浏览网页
• 如果您每天都发照片和视频，3 GB 会比较充裕
• 只有在您需要看流媒体视频或用移动数据办公的情况下，才需要 5 GB 或更多的流量

通常“每天 1 GB”的建议是针对没有 Wi-Fi 的设备在日常居家环境下的使用情况，并不适用于旅行场景。大多数酒店、咖啡馆和机场仍然会提供 Wi-Fi，可以用来处理耗流量大的任务。建议先买小流量包，不够再充值——这样比一次性购买用不完的流量要划算。

Buy and install before you fly. Activate after you land. These are two different steps and confusing them is the most common mistake.

Installing writes the profile onto your phone and needs an internet connection — which you have at home and may not have at the airport. Activation happens automatically the first time the eSIM connects to a network at your destination, and that is when the validity period starts counting.

So installing early costs you nothing: a 7-day plan installed three days before departure still gives you 7 full days from the moment you land. Waiting until you arrive means standing in an arrivals hall trying to find Wi-Fi to install a product you already paid for.

A local SIM bought in-country is often cheaper per gigabyte. A travel eSIM is cheaper in total cost for most trips, once you count what the local SIM actually requires.

Buying locally usually means: finding an official store rather than an airport kiosk with tourist pricing, showing your passport for registration (mandatory in many countries), losing your own number while the SIM is in the phone, and spending an hour of a short trip doing it.

A local SIM makes clear sense for stays of a month or more, or if you need a local phone number for deliveries and bookings. For a trip of one to three weeks, the eSIM usually wins on total cost including your time — and you keep your own number active for banking codes.

不需要。欧洲区域套餐只需一个 eSIM 配置文件，即可在所有覆盖的国家/地区使用。您在跨越国境时无需进行任何切换，也无需安装第二张 eSIM。

是否选择区域套餐取决于您要去的国家数量。在我们的套餐中，一个 5 GB / 30 天的区域套餐平均价格约为 38 USD，而同样规格的单国套餐平均价格约为 28 USD。因此，区域套餐的价格大约要高出三分之一。

一个简单的判断法则是：如果只去一两个国家，就购买单国套餐；如果要去三个或更多国家，就购买区域套餐。如果您去的国家少于三个，购买区域套餐就意味着您会为用不上的覆盖范围支付额外的费用。

Per country is cheaper per plan; regional is cheaper once you cross about three countries.

Measured across our own catalogue, a 5 GB / 30-day plan averages 28 USD for a single country and 38 USD for a regional plan. The regional premium is roughly 37 percent.

So two single-country plans (about 56 USD) already cost more than one regional plan. But you rarely need a full 5 GB in each of two countries — two 1 GB plans would be far cheaper than a 5 GB regional plan. The honest answer is to size the data first, then compare, rather than assuming regional is automatically better value.

主要有以下四种“陷阱”：

• 有效期从购买日而非激活日算起。 有些运营商在您付款后就开始计时。请确认套餐的有效期是从首次连接到网络时开始计算。
• “无限”流量套餐达到“公平使用”上限后会降速。 所谓的“无限”通常指在达到一定流量上限前可享用全速网络，之后网速会降至 512 kbps 或更低。
• 区域套餐的覆盖范围可能不完整。 以某个岛屿或地区命名的套餐，可能因政治或技术原因仅覆盖该地区的部分区域。
• 充值套餐比初次购买更贵。 如果在旅途中用完流量，后续充值的每 GB 价格可能会高于初次购买的价格。

这些信息都不会显示在价格标签上。无论您从哪家服务商购买，都建议在付款前仔细核对这些细节。

Yes, with two checks worth doing.

The eSIM itself is safe by design. A profile is a carrier credential written to a secure element in your phone. It cannot read your data, your messages or your other SIM. Deleting it removes it completely.

The purchase is where care is needed. Buy from a provider that shows the exact networks and countries a plan covers before payment, states its refund position clearly, and can be reached by a human when something breaks. A cheap plan from a seller who disappears when the line does not connect is the real risk, not the technology.

One practical safeguard: a QR code can normally be installed only once. Do not share it, and do not buy from anyone reselling codes second-hand.
