What if whatsapp can't receive the verification code?

There are five main reasons why whatsapp can't receive the verification code: WhatsApp server blocked China's mobile phone number, operators restricted receiving overseas short messages, mobile phone settings blocked overseas short messages, WhatsApp short messages were regarded as spam messages by operators, and the sending of short message verification code failed.

1, WhatsApp server blocked China's mobile phone number.

WhatsApp server may have blocked Chinese mainland's mobile phone number, making it impossible to send verification code SMS to China's mobile phone number. This is mainly because some criminals used virtual mobile phone numbers for illegal operations in the past. To prevent this, WhatsApp chose to turn off the verification code support for China's mobile phone number. This is also the main reason for not receiving the verification code.

2. Operators have restricted overseas SMS reception.

Some operators may restrict receiving overseas short messages, so that the verification code short messages sent by WhatsApp cannot be sent to users' mobile phones. Some operators will selectively block some overseas short messages in order to reduce the harassment to users. This also makes it difficult to receive WhatsApp verification code to some extent.

3. The mobile phone settings block overseas SMS.

Some Android phones also offer the option of setting overseas SMS interception. If the user opens this function himself, he will not be able to receive the WhatsApp verification code message. In Settings-Security and Privacy, you can check whether the function of blocking overseas SMS is turned on.

4.WhatsApp messages are regarded as spam messages by operators.

Individual operators may judge WhatsApp authentication SMS as spam and filter it out directly. This will also cause the verification code not to be sent to the user's mobile phone. However, this situation is rare.

5. Sending SMS verification code failed.

Due to the excessive pressure of SMS sending on WhatsApp server or the abnormal sms channel, the sending of personal mobile phone number verification code may also fail, requiring multiple attempts.
