Detailed Warming-up Steps:
1. Consistent Identity: Once set, do not frequently change your account name or profile picture.
2. Avoid Residual Data: If the number was previously used, do not respond to old messages as it might lead to a ban.
3. Daily Messaging: Send messages to 3-4 contacts daily, preferably those saved in your phone’s contact list. Aim for over 20 text messages without links.
4. Voice and Video Calls: Make voice calls lasting over 5 minutes and, if possible, video calls.
5. Avoid Group Creation: Do not create groups with new accounts as it poses a high risk of being banned.
6. Consistent Activity: Follow these steps for 10 days to ensure WhatsApp recognizes the account as normal. After this period, you can start sending messages but avoid bulk messaging.
