To help our users clearly understand UUPAY's eSIM product categories and select the most suitable option based on specific use cases, this guide details the platform's two core offerings: Short-Term Plans and Permanent Plans.
Short-Term Plans
Short-Term Plans are digital network plans designed specifically for temporary internet access needs.
Functional Scope: These plans include cellular data only and do not feature or assign a phone number.
Service Limits: Once activated, the device will only have the ability to connect to the internet and use mobile data. Because there is no associated phone number, it does not support voice calls or any SMS processing (neither receiving nor sending text messages).
Common Use Cases: This option is ideal for cross-border tourism, short-term business trips, or temporary exhibitions where fast, convenient, and data-only access to local high-speed mobile networks is required.
Permanent Plans
Permanent Plans are digital network plans designed for long-term business maintenance, cross-border identity verification, and scenarios that require a fixed overseas contact method.
Functional Scope: In addition to providing standard mobile data, these plans assign and bind a dedicated overseas phone number to the eSIM profile.
Service Limits: For security compliance and channel reliability standards, the functionality of the assigned phone number is specifically limited. It only supports receiving incoming SMS (such as registration verification codes and system notifications from various platforms). It does not support sending outgoing text messages, and the number does not support any voice calls (neither making nor receiving calls).
Common Use Cases: This option is well-suited for long-term registration and maintenance of various overseas social media, e-commerce platforms, or cross-border financial accounts that require a fixed number to regularly receive verification text messages.
