What to do if you have a poor signal and cannot make calls on your Samsung Galaxy device

Poor signal can limit your ability to make and receive calls and connect to the internet. Try these common solutions for weak or nonexistent phone signals.

Check your carrier settings

• Make sure your account is active.
• Ensure you haven't reached any usage limits.
• Contact your service provider to inquire about potential outages.
• Verify that you are within your service provider’s coverage area.
  * This can vary by service provider.

Change your location

• If you are outdoors:
  
  • Move away from tall buildings
  • Relocate to higher ground
  • Avoid parking garages

   

• If you are indoors:
  
  • Move near a window
  • Go outside.

Remove accessories
Third-party accessories and cases can interfere with the antenna, especially if it claims to boost signal. Also, remove anything that may be plugged into the USB port.

Reboot your device
Turning your device off and back on will close all running apps and force the phone to reconnect to the cellular towers.

Check the physical SIM card

Verify that the SIM card is correctly installed and not damaged. If possible, test with another active SIM card. Your service provider may be able to assist with this if you do not have another SIM.
