No network coverage - Sony Ericsson K550i Cellular Phone

To set Nokia N72 No network coverage problem, go to the network selection ,there select automatic network or try manual search for the network and see if that helps.

try to update using www.updater service.sony ericsson

This probable if your Network does not have 3G/UMTS coverage in that specific area.

I would set your phone so that it will automatically select 2G or 3G network services (e.g. often referred to as Dual-mode) so that if 3G/UMTS is available and has the best coverage/signal, it will automatically be selected. Setting UMTS coverage only would be very restrictive in many area as the signal is usually weaker (especially in Buildings).

Hope it helps!

how can get net work coverage in k800i sony ericsison mobeile phone

your phone must be an imported one if not contact your mobile vendor and have an unlock

change the antenna of your unit, if it doesn't help, your unit needs reformatting or reprogram.

i had no display on my nokia 3230 cellular phone. now its ok but it has no network coverage/no signal . plz help me..... .

Try setting your handset to manual network selection and select the network for your connction provider. If you don't roam around much, this works well. Please revert back to the automatic network selection if you go on Roaming.

Try manually selecting your network. Where are you located?
