3. SMS Configuration (Port 5093)
// 1. Set Server and Port
pw,123456,ip,your_server_address,5093#
pw,123456,ip,your_server_address,5093#
// 2. Set APN (Example: T-Mobile)
pw,123456,apn,://t-mobile.com,,,#
// 3. Request Current Settings
pw,123456,ts#
4. Troubleshooting Common Issues
- Device Offline: Check if the SIM card has data and “PIN Code” request is disabled.
- No GPS Signal: Ensure the tracker has a clear view of the sky. Inside buildings, it may revert to LBS (Cell Tower) positioning.
- Incorrect Password: While `123456` is standard, some batches use `523681`.
- Battery Drains Fast: Reduce the upload frequency (e.g., `pw,123456,upload,300#` for every 5 minutes).
