The activation QR code and illustrated installation guide will be delivered to your email within 30 seconds upon successful payment.

This service is fully supported. Input the traveler’s email address during checkout; the QR code will be sent directly to their inbox while you handle payment only. You can place multiple plans in a single order with separate emails assigned to different travelers, and all activation codes work independently without interference.

Stable WiFi access is required throughout installation, with separate workflows for iPhones and Android devices:

We recommend pre-installing 1 to 3 days before departure while connected to home WiFi. Avoid installing at airports or after landing, where unstable foreign networks often lead to failed scanning and slow loading. Once pre-configured, you only need to turn on Data Roaming to access navigation instantly after arrival.

A restart is unnecessary for most device models. Profiles take effect immediately after scanning and saving. If your Android device fails to detect the eSIM profile, reboot your phone once to resolve recognition errors.

Dual-SIM standby is fully supported. Retain your domestic physical SIM to receive verification codes and incoming domestic calls. Set Travel eSIM as the default cellular data line and disable Data Roaming on your domestic SIM to avoid exorbitant international roaming fees, while calls and SMS functions remain unaffected.

All global LemonSIM Travel eSIM packages offer unlimited free hotspot access. You can share mobile data with tablets, laptops and travel companions. Most competing low-cost plans restrict or charge extra for hotspot functions, making our packages more cost-effective for group travel. For detailed usage rules, refer to eSIM Hotspot Sharing Guide .

There is no need to purchase a full new package. Supplementary data add-ons can be purchased online for instant top-ups that reuse your existing eSIM profile without repeated QR scanning and configuration steps.

All Travel eSIM are one-time purchases with zero auto-renewal and hidden deductions. Internet access will be automatically cut off once the validity period ends, and manual reordering is required for continued service.

All travel eSIM are data-only packages without local voice or SMS numbers. Daily communication via WeChat, WhatsApp, FaceTime and Zoom works seamlessly, while ride-hailing, navigation and online payment functions remain fully operational.

Full refunds are available for orders that meet refund criteria with no complicated processing fees.

Live support entrances are placed at the website footer, order emails and product pages. 24/7 bilingual human agents are available to assist with activation failures, network malfunctions and refund inquiries without automated bot replies.

Standard dual-physical-slot iPhones sold in mainland China cannot install eSIM domestically. After traveling overseas, turn on Location Services to scan and activate travel eSIM while retaining your domestic physical SIM card. Only iPhone Air and iPhone 17e mainland versions natively support dual eSIM. Carrier-locked contract phones from domestic operators cannot use overseas eSIM and must be unlocked in advance.

Cellular-version iPads (iPad Pro, iPad Air, new iPad mini) support eSIM. WiFi-only iPads lack cellular modules and cannot install eSIM profiles. iPad installation steps are identical to iPhones; you may use the eSIM independently or connect to a mobile hotspot.

Travel eSIM currently delivers the most cost-effective and user-friendly overseas internet solution. Confirm device compatibility and complete pre-installation at home to eliminate nearly all connectivity issues.
