Hi. You can only attempt to trace/track and locate your Vodafone VF685 phone if:
- You had activated the 'Vodafone Protect' app if it came with one - or a similar app
- Data connection must also be enabled and the phone must have data bundles or airtime
- And the thief must NOT have hard reset (factory reset) it as that will delete either of the tracking apps.
- If the above does not apply, then the best you can do is to open a case and leave the whole to Police Officials' hands :(
