Why can't iphone receive verification code SMS?

1. Go to iPhone Settings-Info-Blacklist to see if the relevant number is blacklisted.

If you can't find the relevant number in the blacklist, you can only receive some kind of verification code, and it may be that your mobile phone number has been blocked by the operator. It is recommended to contact the relevant platform or operator that sent the information.

2. Check the settings of the mobile phone browser. If the security level of the browser is too high or Block All Cookie is set, you may not receive the verification message.

Please turn on iPhone settings and turn off and block all Cookie in Safari browser.

3. In addition, some websites or platforms also have relevant restrictions. When the number of short messages sent by the mobile phone exceeds the maximum limit of one day, it is impossible to continue receiving verification short messages. You can try again another day.

4. The storage of the mobile phone is full: If the storage space of the iPhone is insufficient, it is recommended to delete unnecessary text messages or other contents first, and then try to see if you can receive text messages.

5. If "Filter out iMessage messages from unknown senders" is turned on, relevant iMessage messages sent by strangers will not be received. If necessary, you can turn "Filter Unknown Senders" off or on in iPhone Settings-Info.
