Will the SMS secondary card remind you that the traffic exceeds the limit?

If you use Unicom number, it is suggested that you can customize the flow of your card in the following ways, and this opportunity will receive SMS:

If your card is a secondary card, log in to the lobby with your mobile phone number and customize a traffic package yourself. After the customization is successful, you will send a short message to your mobile phone. The traffic is also your mobile phone, so you can't share it with the main card. But after the monthly statement comes out, there will still be this fee on the joint account of the main and auxiliary cards, which is your father's mobile phone number ~

Reminder: Due to different policies in different provinces, the businesses launched are also different, subject to local customer service or business hall consultation.
