# Support & Troubleshooting TWTG provides a [service desk portal](https://twtg.atlassian.net/servicedesk/customer/portals) for customers to send questions to or report malfunctions. The customer must provide the serial number of the device along with their situation so that TWTG can better assess the situation. Please note that the LED status and the LED sequence when activating the device provide insights into the issue the device is presenting. Additionally, the LoRa data frames sent by the device provide information on its health, which can be used for troubleshooting. Please refer to the [product manual](/docs/introduction.md) and the respective [communications protocol](/docs/data-and-communication/communication-protocol.md) for more information. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
