Be careful

An update of the Siemens S25 firmware is always possible. Within the guarantee period this is free. Afterwards there has to be a malfunction to receive a toll free update. Additional functions are no reason to receive this. Unfortunately Siemens doesn't have a widespread service network where the update could be done in place. Therefore the phone has to be sent back and force and meanwhile you've got no phone. My hint: On fairs like the CeBIT and IFA an update is often possible toll free in place.

To check the version of the firmware access menu 9-8-2 (IMEI Number) and press the left softbutton.
