Messages on Samsung phone are slow, do not send, or cannot be received

Verify that your account is in good standing and that your service is active. You may need to call your service provider.

Make sure you have an active data connection to your carrier. Temporarily disable Wi-Fi and check for at least a 3G signal in the status bar. 

Alternatively, if your phone and carrier support it, make sure Wi-Fi calling is enabled.

Verify that your phone's SIM card is correctly installed and is not damaged. Contact your carrier if you need help testing your SIM or ordering a replacement.

• If you have another active device on the same network, you may be able to exchange SIM cards between the devices to test them.

• If you have recently changed carriers but kept using the same phone, you may need to contact your current carrier for assistance reprogramming the phone for their service.

If you recently switched from an iPhone, you will need to deregister iMessage.
