Why didn't Ding have the choice of text messages and phone calls?

Hello, if you can't choose SMS or phone when sending Ding, it is recommended to check whether there is still Ding's SMS phone number. If not, it can't be initiated. You can contact the enterprise administrator to recharge it. Tips: If the prepaid ding can't be used, please verify whether the administrator has granted you permission to use it. You can't use the phone/SMS if you don't get permission to use it.
