Android smartphones are powered by a bunch of background services that keep the phone running as it should. However, some of these services deal with cellular connectivity and need to be registered with the carrier’s network before they can be properly used. 

In this article, we’re talking about the IMS registration status not registered error, its causes and what you can do to fix the problem.

What causes this error?

IMS stands for IP Multimedia Subsystem and the service allows your Android smartphone to work with the carrier-provided communications app for better cellular connectivity. There are several reasons why you might see this error show up on your phone:

  • SIM card isn’t connected properly.
  • Incorrect network settings.
  • Carrier outage.
  • Outdated phone software.
