Telecom card SMS can't find traffic

I bought the telecom traffic package online, and the telecom also sent a short message, but the reason why I couldn't find it was basically the system delay, so don't worry. Traffic refers to the information and data generated by mobile phones surfing the Internet. When using a mobile phone to open software or operate the Internet, it will exchange data with the server. Traffic refers to the size of this data.

The unit of traffic is 1024, and the units are b, KB, MB(M) and GB(G).

1G= 1024M

1M= 1024KB

1KB= 1024B
