If you cannot get network coverage anywhere you go, switch the phone off, remove the SIM card, clean the contacts, replace the SIM card and restart your phone.Let me know if that helps.

Did you have network coverage before with the W350a, or was it like this from the start? Have you tried using a different SIM card from the same or a different mobile operator?

The W350a doesn't support GSM 900 frequency, only 850/1800/1900.  You would need to find a service provider that uses GSM 1800 frequency for this phone to work  - it was made for the Americas.
