To help our users clearly understand the underlying technical mechanisms of the UUPAY eSIM and prevent any accidental loss of network plans due to improper operation, this guide outlines the official rules regarding the reinstallation and reuse of eSIM products:
Strict Non-Reinstallation and Single-Use Rules
UUPAY eSIM profiles strictly do not support reinstallation, and they cannot be rescanned or reused once deleted or uninstalled.
Each eSIM activation QR code or manual activation string provided by the platform serves as a one-time, highly encrypted digital credential. Its technical operational rules are detailed below:
Single-Binding Mechanism:
The moment you scan the QR code and initialize the configuration download, the underlying telecom servers permanently pair that specific eSIM profile with your current phone’s hardware embedded chip (eUICC).
No Multi-Device Sharing:
Because of this hardware-level binding, an eSIM that has already been activated on one phone can never be scanned or transferred onto a second phone or any other mobile device using the same QR code.
Deletion Means Permanent Destruction:
If you go to your phone settings and tap "Delete Cellular Plan," "Remove eSIM," or "Delete Smart Card," your system completely erases the communication profile from the built-in chip. Once manually deleted, the QR code immediately becomes void, cannot be rescanned for recovery, and any remaining data or associated phone number rights will be permanently lost.
Critical Operational Best Practices
To ensure your UUPAY eSIM provides uninterrupted global service, please adhere strictly to these operational guidelines:
Never Abort an Installation Midway:
After scanning the QR code, ensure your Wi-Fi connection remains strong and patiently wait for the system to display "Activation Complete" or "Added Successfully." Do not force-quit, power off, or disconnect from the internet while the progress bar is loading, as this will lead to an incomplete or corrupted profile download.
Do Not Attempt Manual Transfers to New Phones:
If your phone breaks or if you purchase a new device and need to migrate your active plan, do not manually delete the eSIM from your old device. Doing so will permanently destroy the credential. Instead, please reach out to our customer support team for guidance on managing device changes.
The Correct Way to Pause Service:
If you are currently back home or temporarily do not require data, never delete the profile. The proper method is to navigate to your device's cellular settings and simply switch the eSIM toggle to OFF. When you arrive at your destination or need the network again, simply toggle it back to ON to resume high-speed access instantly.
Thank you for your continuous support and trust in UUPAY! If you have any questions or experience issues during installation, please always halt your setup and contact our official online customer service team before proceeding with any manual deletions.
