Go to your iPhone's Settings > Tap your Apple ID (your name at the top).
Tap iCloud.
Make sure "Contacts" is toggled ON under "Apps using iCloud."
5. Troubleshooting Common Sync Issues:
Restart Your Phone: A simple reboot can often resolve temporary glitches.
Update WhatsApp: Ensure you have the latest version of WhatsApp installed from your app store.
Clear WhatsApp Cache (Android only): This can fix minor issues without deleting chats. Go to Settings > Apps > WhatsApp > Storage > Clear Cache.
Reinstall WhatsApp (as a last resort): If all else fails, back up your chats (Google Drive/iCloud), uninstall WhatsApp, and then reinstall it. This often resolves stubborn sync problems.
"Importing" a List of Contacts from a File (CSV/Excel)
WhatsApp doesn't have a direct "upload CSV" feature. However, you can use an indirect method:
Create a spreadsheet (Excel whatsapp number list or Google Sheets) with columns for Name, Phone Number, and any other relevant contact details.
Crucially, all phone numbers MUST include the full international dialing code (e.g., +88017xxxxxxx for Bangladesh, +1212xxxxxxx for USA).
Save this file as a CSV (Comma Separated Values)
Import the CSV to Your Google Contacts (Recommended for Android users, or as a general cloud backup).
Tap iCloud.
Make sure "Contacts" is toggled ON under "Apps using iCloud."
