my sony w 810i got no network problem. can it be resolved?

Your problem is the antenna switch or power amp.
Get the phone to a sony ericsson repair centre or your local phone repair guy.
P.S. the wap/mms setting won't work as you cannot receive them... having no signal.

You need to get the Settings for Internet/Wap and MMS from your Network Service Provider. These settings are usually sent as a text msg. When you receive the msg. choose save or install on your phone. Or get the settings directly from their website. The MMS service doesn’t always work between networks.
