How to Fix iPhone 17 Personal Hotspot Not Working After iOS 26.3 Update
iPhone 17 Personal Hotspot Not Working After iOS 26.3 Update usually means the hotspot service failed to restart after the update, carrier settings did not refresh correctly, or Wi-Fi and Bluetooth tethering are no longer advertising properly.

Method 1: Toggle Personal Hotspot and cellular data
This rebuilds the tethering session and often restores hotspot visibility immediately.
- Turn Cellular Data off and back on.
- Open Settings > Personal Hotspot.
- Turn Allow Others to Join off and back on.
Method 2: Restart the iPhone and the device trying to connect
A stale hotspot session on either device can block reconnection after an update.
- Restart the iPhone 17.
- Restart the laptop, tablet, or other client device.
- Try joining the hotspot again using the current password.
Method 3: Check carrier support and carrier settings update
If the line is not provisioned correctly, the hotspot feature may appear but fail to share data.
- Open Settings > General > About.
- Install any carrier settings update prompt.
- Confirm with your carrier that Personal Hotspot is enabled on your plan.
Method 4: Reset network settings
This clears broken Wi-Fi, Bluetooth, and tethering profiles without erasing apps or media.
- Open Settings > General > Transfer or Reset iPhone > Reset.
- Tap Reset Network Settings.
- Turn Personal Hotspot back on and test again.
Method 5: Install the next iOS patch if available
If the problem started right after iOS 26.3, Apple may already have a minor patch that fixes hotspot bugs.
- Open Settings > General > Software Update.
- Install any newer iOS build that appears.
- Retest the hotspot afterward.
