The network status indicator on the Home screen of the BlackBerry device displays SOS. The SOS network status indicator means that you can only place emergency calls. Messages cannot be sent or received, and phone calls cannot be made or received.

This issue may be caused by one of the following:

The Subscriber Identity Module (SIM) card is not properly inserted into the BlackBerry device.
The SIM card is scratched or damaged.
The SIM card contacts are oxidized.
Your service has been disconnected by the service provider.
The network does not support roaming.
The network selection mode is set to manual and no network is selected.
The BlackBerry device requires the latest software from the service provider.
