In 2022, China Mobile suddenly gave away 20g traffic

In 2022, some customer mobile companies often have similar activities, and will send customers a text message while sending traffic. Sometimes you will be prompted to use as much as you need and how much will be given to you the next month. Usually, 5G will continue to be sent the next month after the 5G is used up. You can call for consultation or check if you have received a text message from China Mobile to see if data has been sent.
