China southern power grid tram charging terminal charging without verification code

According to your description, because the charging pile uses SIM wireless communication, this will happen if the communication of the charging pile is interrupted. You can stop charging by clicking the stop button on the charging pile screen and entering the verification code in the short message you receive when you start charging.

Extended data:

1, mobile phone interception If the mobile phone comes with or has installed security software, the normal verification code message may be intercepted under the condition of high security level setting, so that users can't see it. In this case, just lower the security level of the software, or set the corresponding white list, or uninstall the security software directly. 2, mobile phone arrears or poor signal If the mobile phone number is in arrears, the operator will turn off all communication functions of this mobile phone number, and the SMS will naturally not be received. At this time, the main thing the machine does is to charge. If the mobile phone is in a position with poor signal, it may not receive the short message. At this time, the owner needs to move to a good signal position and should be able to receive it. 3, SMS platform failure Most companies' websites and apps are docking third-party SMS verification code platforms, not directly the three major operators. The third-party SMS verification code platform has its own independent management system and channels. At this time, if the platform itself fails or the channel is congested, users will not receive the SMS verification code. 4. The number of messages received on the same day reached the upper limit. There is an upper limit on the number of short messages received by each mobile phone number in a single day. If it exceeds the upper limit, it will be automatically blocked by the operator. In this case, you can contact the operator or try again the next day. It is rare that the mobile phone is full now, because the smart phone is used more now and the memory space is larger, but this situation is not ruled out. In this case, you can receive the check code normally by clearing the memory.
