first of all, sorry for my poor English...

We are using several Nokia 6085 for different tests (voice calls, web/wap browsing, sms, MMS etc...). The problem is that these mobiles never stops working and there is a point in the time when this mobiles becomes frozen and they cannot continue working.
Then, we think the solution could be to reboot these modem one time per day. For doing that, we added an script that executes At+CFUN everydays at 0:00. But this AT Commands doesn't work with these mobiles. We have checked this Command with N70 and 6630 and it works properly, but using it with 6085 it doesn work.
My question is, Is there any AT command to reboot this mobiles?

Thank you very much for your attention & best regards
