Why isn't there a reminder to use up the daily rental package, and there are also tips for all the use information?

There are several reasons for using mobile phones to generate traffic but not receiving traffic SMS reminders:

1. Your mobile phone has been turned off or stopped for more than the time limit for sending SMS (i.e. 24 hours);

2. The SMS storage space is full;

3. Due to the influence of network and rush hour, there may be some time delay or information loss when sending SMS.

For details, please consult the customer service of Unicom.

Inquiries about the usage of various services are different. If you need to inquire about the traffic usage, you can use this number to log in to the online business hall/homepage, and click "phone bill inquiry" > "usage inquiry" > "Internet traffic" to inquire about the usage and remaining situation of mobile Internet traffic in the current month. For other types of business inquiries, you can contact Unicom's manual customer service for consultation.
