Samsung GALAXY S4 - Can't place or receive calls

There could be a number of reasons why you can’t place or receive calls. To resolve the issue, try the following.

Check signal strength

The signal strength may be low.

  • Make sure you have at least two bars of signal strength with 4G or LTE in the network indicator.
  • If you have low signal strength, move to a location with better coverage. Concrete and steel buildings may be hindering reception, especially in elevators and underground locations like basements, subways, and tunnels.
