Why does ABC sometimes receive short messages 1.6 and sometimes 2 yuan?

Different regions have different charging standards and different service contents.

1. Charging standards in different regions: The cooperation agreements signed between telecom operators and Agricultural Bank of China in different regions are different, resulting in a slight difference in the amount of SMS charges in some regions.

2. Different service contents: ABC provides various short message services such as balance inquiry and transaction reminder, and different types of short message services will correspond to different charging standards.
