Abstract
Various embodiments include methods and wireless devices implementing such methods for detecting when the wireless device is operating in a limited service state (LSS) mode, transitioning from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode, and sending a text message or initiating a voice call using the satellite-based SOS mode.

1-28. (canceled)
A wireless device, comprising:
- a processor configured to:
- detect the wireless device is operating in a limited service state (LSS) mode;
- transition from operating in LSS to satellite-based SOS mode in response to the wireless device operating in LSS mode;
- transmit a first text message to initiate a polling sequence by a satellite to check for incoming text messages or voice calls from the wireless device, wherein the first text message is an empty text message;
- and
- during the polling sequence the processor is further configured to:
- receive a response from the satellite to prompt the wireless device to engage in a further communication with the satellite;
- and
- based on the response, engage in the further communication with the satellite by sending a second text message or initiating a voice call using the satellite-based SOS mode.
