Can the calling card receive the verification code?

Yes, but you can't get the verification code of the out-of-service calling card.

1. You can't receive verification code messages after your mobile phone is in arrears. If the mobile phone can't receive the verification code SMS, you can call to see if there is any arrears. If it is arrears, you only need to pay the phone bill in full, but you won't receive the message that you didn't receive during the arrears period, and you need to resend the verification code. 2. It may be a problem with the mobile phone system. You can turn it off, restart it, try again, or clear the phone data. 3. If you are harassed and intercepted, you will not receive the SMS prompt of the verification code. Need to check the SMS interception information to see if it is intercepted. 4. If the SMS storage is full, you can't store new SMS, which leads to the situation that you can't receive SMS. It is recommended to delete the message and try again. 5. If the user has not turned on the phone for a long time or is in a place with poor signal, the arrival of information will be delayed, and generally the verification code will have a valid time. Failure to receive the message for a long time will also lead to the expiration of the message. Suggest trying somewhere else. 6. It may be related to the local gateway. If the amount of local short messages is too large for a period of time, it will also cause the short message center to be busy, so the short messages will also be affected, delayed or lost. I suggest trying again another time. 7. It may also be related to the operator, or the order is inconsistent. In this case, you can call the operator or go to the local business hall with a valid ID card.

1. verification code is generally used to prevent batch registration, which is difficult for people to see, let alone machines. Second, Baidu Post Bar has not become a member of this bar. Probably to prevent a large-scale anonymous reply to the input verification code. At present, many websites adopt verification code technology to prevent users from automatically registering, logging in and pouring water by robots. The so-called verification code is to generate a picture with a series of randomly generated numbers or symbols, and add some interference to the picture, such as drawing a few straight lines randomly and drawing some points (to prevent OCR). Users can identify the verification code information with naked eyes, enter the form and submit it to the website for verification. Only after the verification is successful can a function be used. 2. The place where the general user ID is registered and the major forums should enter the verification code.
