Why is my package traffic lost and there is no SMS notification, which leads to the deduction of the phone bill?

If it is a Unicom user, if the balance of the mobile phone is not enough to deduct the monthly rent, it will lead to arrears.

As far as your phone bill is concerned, if you use more traffic, you will definitely be charged. As for why the traffic is used up, but there is no SMS reminder, first of all, you have to apply for opening the traffic and use the SMS reminder function to get the traffic SMS reminder service.

Due to the delay in the settlement of traffic bills, it takes a certain process to trigger SMS reminders after bills are put into storage. However, a lot of traffic (such as software download, online video watching, online video chat, etc. ) The use time is short, and the package traffic is not triggered in time after use, which will cause this problem.
