My phone is a dual Sim phone. Both Sim cards says they are not registered on a network. I have done all I can to fix the problem. Any suggestions? Everyone around me has signal. It's been weeks.
If you've been experiencing this "Not Registered on Network" issue for both SIM cards on your Galaxy A34, here are several possible solutions to try:
1. Check SIM Card Placement
Power off your phone.
Eject the SIM tray and make sure both SIM cards are seated properly.
Inspect the SIM cards for any physical damage or dust. Clean gently with a soft cloth if necessary.
Reinsert the SIM cards, turn the phone back on, and check for network registration.
2. Test SIM Cards in Another Phone
Insert your SIM cards into another phone to see if they work. If they don't, the issue might be with the SIM cards themselves, and you may need to contact your carrier for replacements.
3. Update Your Phone’s Software
Ensure your Galaxy A34 is running the latest software version. Sometimes network issues are resolved in system updates.
Go to Settings > Software Update > Download and Install and check for any available updates.
4. Reset Network Settings
This will reset Wi-Fi, Bluetooth, and mobile data settings, so you’ll need to reconnect to Wi-Fi afterward.
Go to Settings > General Management > Reset > Reset Network Settings.
Confirm and restart your device, then check if the network registration issue is resolved.
5. Select Network Manually
Go to Settings > Connections > Mobile Networks > Network Operators.
Toggle Select Automatically off and let the phone search for available networks.
Try selecting your carrier manually from the list. If this works, you can turn Select Automatically back on.
6. Check for SIM Lock or Carrier Restrictions
If your phone is locked to a specific carrier, and you’re trying to use SIMs from different carriers, it may cause this issue.
Check if your phone is unlocked by contacting your carrier or reviewing your phone's documentation.
7. Switch Between 4G/3G Networks
Some network issues may be related to your preferred network type (e.g., 4G, 5G).
Go to Settings > Connections > Mobile Networks > Network Mode and switch between 4G/3G/2G (auto) and 3G only to see if either mode works.
8. Contact Your Carrier(s)
Since this issue has persisted for weeks, your carriers may be able to check on their end for any account-related problems, such as provisioning or network compatibility issues.
9. Factory Reset (as a Last Resort)
If nothing else works, you may need to perform a factory reset as a last option, but back up all your data first.
Go to Settings > General Management > Reset > Factory Data Reset.
If the problem persists after these steps, it's possible that there may be a hardware issue with the SIM tray or the phone's network modules. In that case, it would be best to have the device inspected by a Samsung service center or an authorized repair technician.
