加那利群岛 eSIM

请根据手机的详细型号和销售地区，查询制造商提供的兼容列表，并确认您的手机没有被任何运营商锁定。手机设置中能找到 EID 或“添加 eSIM”选项通常说明支持，但不同地区的版本仍可能有差异。如果不确定，建议您在购买前联系客服确认。

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 Cellesim 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 Cellesim 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.

If an eSIM does not work and you have not used the data, we refund it in full to the original payment method. There is no restocking fee and you do not need to return anything.

In practice we check the line on the carrier side first, because most failures are a stuck data session that we can restart remotely in a few minutes. If the line genuinely cannot be made to work in your location, we refund.

To be straightforward about the limit: once a plan has been used, a refund is no longer possible, because the data has already been bought from the network operator on your behalf. In that case we look at a replacement instead. If a plan was never activated, the refund is simple.

Yes. Every Cellesim account has a wallet balance, and you earn 5 USD of store credit for each friend who buys their first eSIM with your referral link.

The credit lands in your wallet automatically once their order completes, and it is applied to your next purchase — you do not need a coupon code. Wallet balance never expires.

Your referral link is in your account. There is no limit on how many people you can refer, and the person you refer also gets a discount on their first order.

Cellesim 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 Cellesim 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.
