What should I do if I cannot send or receive SMS on my Samsung Phone?

Last Update date : 2023-05-16

It is often a problem with the carrier or its service if you are experiencing difficulties sending or receiving messages or if they appear sluggish. Other times, if you recently moved from an iPhone, iMessage may still be activated, which might cause texts to be lost in the ether.

1 Check the status of your carrier's service.

Check to ensure that your account is in good standing and that your service is operational. You should contact your service provider.

  • Open Settings, then browse to and tap Apps.
  • Locate and then tap Messages.
