It is suggested that the IVR process of voice recharge is different in different provinces, so it is recommended to call the test recharge yourself. Generally, you need to enter your personal bank card number, ID number (corresponding to the first recharge and bank card) and transaction password. There are also different regulations, for example, Gansu Mobile can only recharge this machine for the first time, so it is suggested to consult the local business hall or 186, subject to the results of local consultation.
