When an Xentissimo or Xenta terminal is using a Telstra GPRS sim card and the connection becomes weak or unstable, it will display an error message 'Sign on failed - Poor GPRS Signal'.
To troubleshoot this issue please:
- Reboot will resolve the problem (How do I Reboot My Tyro Machine?)
- Visit the Telstra Service Status website and enter your postcode. If there are any issues in the area they will be outside of Tyro's control.
If you have a working WIFI connection follow the How do I setup WiFi network on my Terminal? procedure.
Please be aware that as of December 2016 Telstra will be removing their GPRS network. If you do not have a WiFi network please contact Customer Support on 1300 966 639 for further assistance.
