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