Will the confirmation code sent by the mobile phone or system consume your own phone bill and traffic?

Generally speaking, the confirmation code sent by mobile phone or system will not consume your phone bill and traffic.

Usually, when you use your mobile phone or system to send confirmation codes, these confirmation codes are sent by SMS or email. If you use SMS, the confirmation code will not consume your phone bill, because your mobile phone package already contains a certain number of SMS. If you use email, sending the confirmation code will not consume your traffic, because your mobile phone traffic package already contains a certain amount of data traffic.

Of course, if you run out of SMS or traffic in your mobile phone or traffic plan, you need to buy additional SMS or traffic. In this case, sending a confirmation code will consume your phone bill and traffic.
