Isn't it a reminder that Unicom's traffic is used up?

Generally, when the traffic in the package is running out or running out, there will be relevant SMS reminders. For example, there are several reasons why the traffic is deducted when surfing the Internet with a mobile phone, but the SMS reminder of the traffic is not received:

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

2 SMS storage space is full;

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

If the above reasons are excluded, it is suggested that you can contact the Unicom customer service where the number belongs to verify the relevant reasons.
