What you want to ask is that Unicom changed the 8 yuan package, and the customer service said it would take effect next month, but there was no text message. What happened? System delay, privacy settings, contact information errors. According to the official website, check the exchange room.

1. System delay: the operator sends SMS notification to the user after changing the package, but the SMS cannot be delivered in time due to system delay or failure.

2. Privacy settings: The user's privacy settings will prevent or filter the receipt of SMS notifications. Make sure that the mobile phone settings do not identify the SMS of the operator as spam or block it.

3. Incorrect contact information: If the mobile phone number is wrong or changed when the operator registers, it will be impossible to send SMS notification.
