Issue

iPhone users are mostly reporting issues about not receiving the activation PIN/code for WhatsApp as an OTP. The following table lists the possible cause(s) and troubleshooting step(s):

Cause

The issue lies with the following entities:

• Meta / WhatsApp
• Apple / iPhone

This issue occurs in WhatsApp and WhatsApp Business Apps. As a result, the same issue is observed in WhatsApp Phone Archiver.

Troubleshooting Steps

Some potential fixes are:

• Network Issues:A stable internet connection is crucial for
  receiving OTPs. Ensure that your iOS device has
  a reliable internet connection through cellular
  data.
• Do Not Disturb Mode:If your iOS device is in the “Do Not Disturb”
  mode, it may suppress notifications, including
  OTPs. Make sure that your device is not in this
  mode when expecting an OTP.
• iMessage Issues:If you are using iMessage for SMS, ensure that
  iMessage is activated and working properly. If
  you encounter issues, you may try temporarily
  disabling iMessage to receive OTPs via standard
  SMS.
• iOS Settings:Check your iOS settings to ensure that messages
  and notifications are allowed for the relevant
  apps, including the one generating the OTP.
• iOS Updates:Ensure that your iOS device is running the latest
  version of the operating system. Updates may
  include bug fixes and improvements that could
  address any issues related to OTP delivery.
• Blocked Contacts:Ensure that the sender’s number is not blocked on your iOS device.
• Filter unknown senders:Ensure that the setting to filter unknown senders
  is turned off.
• Activate WhatsApp Business on Android and
  then migrate to WhatsApp on an iPhone:
  

1. Activate the same number with WhatsApp
   Business app on an Android phone.
2. Migrate your app to WhatsApp on your iOS
   device.

Note

You will need two phones to accomplish this.
