Voice calling, including to 911, is not supported over satellite at this time. There are circumstances under which text-to-911 service over satellite may not be available or may be limited in comparison to traditional text-to-911 service. Those circumstances may include potential delay in connecting the text-to-911 service, potential inability to determine your location and telephone number, potential consequences of moving into or out of terrestrial coverage during a text exchange, potential inability for your device to connect to the satellite, and potential issues in connecting between satellite and terrestrial networks. Some 911 text messages over satellite may be delivered to an emergency call center, rather than to a traditional 911 answering point. The emergency call center may not be able to contact local emergency authorities or may be delayed in doing so. All satellite messages, including 911 messages, are subject to delivery delays.
