Hi Riisbjerg,
you could try to reset/clear flash the phone. That should take care of the problem, but it also erases ALL settings and phone book entries from the phone, so it is best to make a backup of the phone bookwith the PC tools software.
The software can be downloaded from http://www.sonimtech.com/support/downloads.php
Reset:
Please try to reset the handset memory as below:
a. After Powering ON the phone
b. press #20070114# from phone idle screen and press dial key.
c. Message comes up as " Do you really want to clear flash? "
d. Select OK. After reset is finished, you can see the message "Switch off the mobile by any keys".
e. Switch the phone off, then remove and reinsert the battery and Power ON the phone.
Once done, please restore the handset to factory settings:
a. Power the handset on
b. Using the menu buttons, go to Settings (General Tab) -> Default Settings.
c. Press the OK button to confirm
d. Power the handset on again
If this does not help, please send an email to the Sonim support team:
