How to Fix WhatsApp Not Working on iPhone: 5 Simple Solutions

Update WhatsApp

• 💡 Updating the app is the most common and important step to ensure WhatsApp functions correctly on your iPhone.
• 📌 To update, search for WhatsApp in the App Store; if an update is available, tap 'Update' or 'Resume'. If it shows 'Open', tap the app name to reveal the update option.

Check App Permissions

• ⚙️ Permissions for WhatsApp can be managed in your iPhone's Settings app under the WhatsApp section.
• 🔑 Ensure permissions for contacts, photos, microphone, notifications, background app refresh, and mobile data are enabled for full functionality.
• 📍 For location sharing, enable 'While Using the App' or 'Full Access' and verify Location Services are enabled in Privacy & Security.

Restart Your iPhone

• 🔄 A simple restart can resolve many app issues. Press and hold the power and volume buttons, then slide to power off.
• ⚡ After waiting about 10 seconds, press and hold the power button until the Apple logo appears to restart your device.

Reinstall WhatsApp

• ⚠️ Before reinstalling, ensure you have access to your phone number for verification and back up your chats within WhatsApp settings (Settings > Chats > Chat Backup).
• 🗑️ To reinstall, long-press the WhatsApp icon on your home screen, select 'Remove App', then 'Delete App', and confirm.
• 📲 Download WhatsApp again from the App Store and set it up.

Free Up iPhone Storage

• 💾 If WhatsApp is still not working, low iPhone storage might be the cause. Check available storage in Settings > General > iPhone Storage.
• 🧹 Delete unused apps or 'offload' them to free up space. Photos and videos also consume significant storage; delete duplicates or unnecessary media.
• ♻️ Remember to clear the 'Recently Deleted' folder in Photos to permanently free up space. After freeing storage, restart your phone again if necessary.
