Seeing a "No SIM Card Detected" error on your Google Pixel 9 Pro can be frustrating, especially when you can't make calls or send texts. This common issue usually stems from simple hardware or software problems that you can often fix yourself.
Quick Fixes for Your Pixel 9 Pro
To fix the "No SIM Card Detected" error on your Google Pixel 9 Pro:
- 1.Restart your phone
- 2.Toggle Airplane Mode on and off
- 3.Remove, clean, and reinsert the SIM card
- 4.Check if the SIM card is enabled in Settings
- 5.Reset network settings
- 6.Test your SIM in another phone
If these don't work, the issue may be with the SIM card itself (requiring replacement) or your phone's hardware (requiring professional repair).
What Causes the "No SIM" Error?
Hardware-related causes include a SIM card that's not inserted correctly, dirty or damaged contacts, a bent SIM tray, or a damaged internal SIM card reader. The Tensor G4 modem in the Pixel 9 Pro can sometimes be less robust in weak signal areas, which may contribute to detection issues.
Software-related causes are temporary glitches, outdated Android 15 software, corrupted network settings, or third-party app conflicts.
Account-related causes involve a SIM card deactivated by your carrier, a phone locked to a different carrier, or older SIM cards that aren't fully compatible with modern networks.
Start With These Basic Steps
Begin with these simple troubleshooting steps that solve most SIM card detection issues on your device.
Restart Your Google Pixel 9 Pro
A simple restart often resolves temporary glitches. Press and hold the Power button until the power options appear, then tap "Restart." If the phone is unresponsive, you can force restart it by pressing and holding the Power button for 30 seconds or more until it reboots.
Toggle Airplane Mode
Swipe down from the top of your screen to open the notification panel. Tap the Airplane mode icon to enable it, wait 10-15 seconds, then disable it. This refreshes your phone's network connection.
Verify SIM Card is Enabled
Make sure your SIM card is actually turned on in your phone's settings:
- Open Settings
- Tap Network & internet
- Go to SIMs
- Ensure your SIM is toggled on
Inspect the Physical SIM Card and Tray
If the quick fixes don't work, check your SIM card and tray for physical issues:
- 1.Power off your phone completely.
- 2.Remove the SIM card from its tray using the SIM ejector tool.
- 3.Inspect for damage - look for scratches or corrosion on the gold contacts.
- 4.Clean the SIM card - use a clean, dry microfiber cloth to gently wipe the contacts.
- 5.Check the SIM tray - ensure it's not bent or damaged.
- 6.Reinsert carefully - make sure the SIM card is properly aligned in the tray.
Test your SIM in another phone: If your SIM card fails in another unlocked device, contact your carrier for a replacement. If it works, the issue is likely with your Pixel 9 Pro.
Software and Network Solutions
Update Your Software
Software glitches in Android 15 can cause SIM detection problems. Check for updates:
- Open Settings
- Tap System → System update
- Download and install any available updates
Also update Google Carrier Services from the Play Store, as this app handles carrier connectivity.
Reset Network Settings
This clears any network configuration issues without deleting your personal data:
- Go to Settings → System
- Tap Reset options
- Select Reset Wi-Fi, mobile & Bluetooth
- Confirm the reset
Note: This will reset Wi-Fi passwords, Bluetooth pairings, and mobile network settings.
Change Network Mode
Ensure your phone can automatically switch between network technologies:
- Open Settings → Network & internet
- Tap SIMs → select your SIM
- Tap Preferred network type
- Choose 5G (or allow automatic switching)
Reset APN Settings
Incorrect Access Point Name settings can prevent a network connection:
- Go to Settings → Network & internet → SIMs
- Select your SIM, then tap Access Point Names
- Tap the menu (three dots) → Reset to default
eSIM Troubleshooting on Pixel 9 Pro
If you're using an eSIM instead of a physical SIM card, the troubleshooting steps are slightly different.
Check eSIM Activation Status
- Go to Settings → Network & internet → SIMs
- Look for your eSIM profile listed
- If it shows as inactive, try restarting your phone
Re-download Your eSIM Profile
If your eSIM isn't working:
- 1.Go to Settings → Network & internet → SIMs
- 2.Tap your eSIM, then Delete
- 3.Re-scan the QR code from your carrier or re-enter the activation code
- 4.Ensure you have a stable Wi-Fi connection during activation
Advanced Troubleshooting Steps
Boot into Safe Mode
Safe Mode disables all third-party apps, helping you determine if an app is causing the issue on your Google Pixel 9 Pro:
- 1.Press and hold the Power button.
- 2.When the power menu appears, press and hold Power off on the screen.
- 3.Tap OK to restart in Safe Mode.
If your SIM works in Safe Mode, a recently installed app is likely causing the problem. Uninstall apps one by one to identify the culprit.
Verify Your IMEI Number
A corrupted IMEI can prevent your phone from connecting to cellular networks:
- 1.Open your phone's dialer
- 2.Type *#06# and press call
- 3.Your IMEI number should appear as a 15-digit number
If the IMEI shows as "null" or "unknown," your phone's software may be corrupted.
Check for 5G SIM Compatibility
If you recently got your Pixel 9 Pro, your older SIM card might not support 5G networks optimally. Contact your carrier to get a 5G-compatible SIM card, or ask about converting to an eSIM.
Consider Switching to eSIM
If your physical SIM keeps failing, ask your carrier about converting to a digital eSIM. This can resolve persistent "No SIM" issues and eliminates physical connection problems entirely.
Factory Reset
If nothing else works and the problem appears to be software-related, a factory reset may help. Back up all your data first:
- Go to Settings → System
- Tap Reset options
- Select Erase all data (factory reset)
- Follow the prompts to complete the reset
