Will the calling card be blocked when sending text messages?

Whether the calling card will be blocked or not depends on the situation.

If the calling card is a white list calling card, even if real-name registration system is required to register, it will not be sealed. However, if you use your mobile phone card to send short messages about marketing promotion activities, it may be blocked.

Therefore, when sending short messages, especially when using mobile phone cards to send marketing short messages, we should pay attention to whether it will trigger the title blocking mechanism.

This information may be updated with the changes of time and market environment. It is recommended to pay close attention to relevant policies and regulations or consult relevant service providers, and then decide to use calling cards to send short messages after obtaining more accurate information.
