Dear RAKsmart user,

We are planning to conduct a system upgrade from 12:00-16:00 PM on October 20th, US Pacific Time (3:00-7:00 AM on October 21th, China time).  This upgrade will temporarily disable your user backend, which may result in short disruption of your service. We apologize for any inconvenience this may cause and appreciate your understanding and support.

Please feel free to contact us through our ticket system should you have any question.

Thank you again for your understanding and support！
