Rtc changing to future date


I am using Q24pl001 for our application.
I am also using GPRS facility available with this module.
In our application the module is working fine for somedays , after that date is getting changed to some future date.
We are using varta 3v battery for rtc backup, so kindly share your experience regarding this.


I am experiencing the same problem - did you ever determine the cause of this issue and/or determine a fix/workaround?


I had the same problem. Our dealer told this problem to Wavecom. Wavecom found the problem and its supposed to be corrected in new Firmware 657h
