Do prepaid cards have SMS exchange methods?

Take Jiangsu Unicom as an example:

1. You can send the short message "JFDH" to 100 10 with the mobile phone that you want to redeem the recharge card, and the system will send the service code of the recharge card that the mobile phone can currently redeem to the mobile phone;

2. Send the short message "JFDH# service code" to 100 10 using the mobile phone that wants to redeem the prepaid phone card, and the system will automatically charge the phone bill to the mobile phone account that redeemed the prepaid phone card. After successful redemption, the redeemed recharge card cannot be used to recharge other mobile phones.

A hundredfold care, 10 satisfaction.
