Troubleshooting
The phone does not switch on
Remove/reinstall the battery. Then charge the
phone until the battery icon stops scrolling. Unplug
from charger and try to switch the mobile on.

Contact your operator.

contact your network operator for assistance/

The display responds more slowly at very low
temperatures. This is normal and does not affect the
operation of the phone. Take the phone to a warmer

your phone supplier.

phone.

This feature is network and subscription dependent.
If the network doesn’t send the caller’s number, the

Contact your operator for detailed information on
this subject.
