Why did I send a text message saying that there was a traffic charge when I rented my card for 6 yuan a day? Isn't it 500M a day?

The daily card rental fees in different cities are different. For example, the daily card rental fee for Beijing Transportation is:

[1] 5 yuan/month, including caller ID. By default, 4G Internet access is enabled;

[2] Local calls are 0. 12 yuan/min, domestic calls are 0. 15 yuan/min, and local calls are free;

[3] The package includes 50MB of local traffic, with a bonus of 1 yuan to enjoy 500MB of local traffic every day. When the traffic is used, it will be automatically deducted, and if it is not used, it will not be deducted;

[4] Send SMS 0. 1 yuan, MMS 0.9 yuan;

[5] Other rates depend on standard rates.

Tips: Local traffic refers to the traffic generated when the mobile phone number belongs to the country (not roaming) and cannot be used in different places. For details, please contact the local Unicom customer service.
