Frequently Asked Questions
Find answers to the most common questions about our eSIM service.
eSIM（嵌入式 SIM）是一种数字 SIM，无需实体 SIM 卡即可激活蜂窝套餐，信息以数字方式写入设备。
购买套餐后您会收到二维码。用手机扫描即可安装 eSIM 配置文件，到达目的地后激活数据即可上网。
建议在出发前安装，到达目的地后再激活数据。有效期通常在 eSIM 首次连接当地网络时开始计算。
可以。eSIM 可与现有 SIM 并存：通话/短信用原号码，上网走 eSIM 数据。请在手机设置中将 eSIM 设为数据线路。
购买后几乎立刻收到二维码。可使用一键安装或扫码，通常约 2 分钟即可完成。
可以，我们强烈建议提前安装。可在家完成安装，到达后通常会自动连接当地网络。
许多支持 eSIM 的手机可保存多个配置文件，但同时可激活的数量因机型而异，请查阅设备说明。
iPhone XS 及更新机型、Samsung Galaxy S20 及更新、Google Pixel 3 及更新等众多智能手机均支持。具体以厂商说明为准。
自 iPhone XS（2018）起多数机型支持 eSIM。中国大陆等地区部分机型可能有所不同。
许多安卓机型支持。可在设置中查看是否有「添加 eSIM」等选项。
取决于所购套餐。若套餐说明中包含热点功能，则通常支持。购买前请查看详情。
若 eSIM 尚未安装或激活，可申请全额退款。一旦在设备上安装，则无法退款。如有问题请联系客服。
所有价格均以欧元（EUR）显示。若使用其他货币支付，银行可能收取汇兑手续费。
流量用尽后数据将停止。您可购买新的 eSIM 套餐。已安装的 eSIM 仍保留在设备中。
For most short-term travel, yes. eSIM avoids airport SIM queues, lets you install before flying, and you keep your home physical SIM for voice/SMS. Physical SIMs only beat eSIM in countries where the local prepaid plan is dramatically cheaper than any travel eSIM and you stay long enough to justify the swap.
Most travel eSIMs allow hotspot/tethering so you can power a laptop or share data with a travel partner. Some "unlimited" plans throttle hotspot speed after a daily cap — check the product page before purchase.
Yes. Regional eSIMs cover multiple countries on a single QR profile (Europe 30/40, Asia 20, Balkans 5, Central America). Global eSIMs cover 100–190 countries with one QR. Country plans only work in their listed country.
Usually yes — once you turn airplane mode off after landing the eSIM connects to a partner network within seconds. If it does not connect, manually pick "Auto" network selection and toggle data roaming ON for the eSIM line (this is safe because the eSIM has its own prepaid allowance).
Yes. All iPhone XS and later support eSIM (US iPhone 14+ is eSIM-only). On Android: Google Pixel 4+, Samsung Galaxy S20+ globally, Galaxy S23/S24 in many regions, plus most modern Huawei, Oppo and Xiaomi flagships. Check Settings → Mobile/Cellular → "Add eSIM" before buying.
No — travel eSIMs are data-only. Keep your home physical SIM as the voice/SMS line. Use WhatsApp, iMessage, Telegram, Signal, FaceTime or Google Voice for calls over the eSIM data line.
For most providers the validity countdown starts the first time the eSIM connects to a local network in the destination — not at purchase. So you can buy days or weeks ahead without burning validity time.
Yes — eSIMs that never installed or never activated can be refunded. Once you activate and consume data, partial refunds depend on the provider policy. Always check the refund terms before purchase.
Modern iPhones store at least 8 eSIM profiles (only 2 active at once). Most modern Androids store 5–8 profiles. You can keep one eSIM per country/region and activate only the one you currently need.
Almost always. Pocket Wi-Fi devices cost €5–€15 per day to rent, plus a daily data allowance. An eSIM for the same duration usually costs less than a single day of pocket Wi-Fi and you do not have to carry another device or charger.
