When inserting the SIM card, be sure to follow the procedure in Inserting a SIM Card (page 68). ❑ Your mobile phone network needs to cover your area. Contact your network provider for information on the network coverage. ❑ Make sure the WIRELESS switch is on and the WIRELESS indicator light is lit on your computer. ❑ Make sure the switch next to Wireless WAN is set to On in the VAIO Smart Network window. ❑ You may need to manually enter Access Point Name (APN) information in your connection manager software.
