Motorola mobile I have purchased motorola w205, it works well, but onething bother me is the display does not show the place or area of the tower. how can i set this?

What service provider is it? The card will still work, I am still using mine that expired 2 years ago! You can top up at most shops or supermarkets over the counter by giving your telephone number!

Valleys close to wireless towers usually cause call drops. Wireless carriers are always competing for coverage areas and improvements in reception. Switching carriers or buying prepaid emergency phones for dropped call areas is helpful.

Your best bet is to ring your cell phone and hope the personwho answers your cell phone will return your phone to you. Otherwise I suggest you contact your cell phone providerASAP.

To unlock your phone, read the information from this link.

It says "No Service" on my phone display. When the phone is first turned on, it displays "No Service" for about 30 seconds while it connects to the cellular network. This is normal. The message should disappear after 30 seconds.
If the "No Service" message stays on, you may be in a location where the cellular signal is too weak, such as a subway or mountain valley, or where a cellular tower is not close enough to your phone. Weather or environmental conditions may also be a factor. Try your call again from another area.
If "No Service" stays on in an area where you think you should be getting reception, turn the phone off and back on. If you still get "No Service," use a land line to call our Customer Support team at 1-888-345-5509.

Your inner display may be damaged.Contact the Authorized Motorola customer care to replace it

Rest code for motorla mobile w205

I too faced a similar problem, but recently i got it unlocked, if you have any more queries , you can see here

Hai
It seems your area is having less signal strength or its far from the mobile tower of your service provider.
Its a problem for lots of people around.
Try change the service provider or move to the nearest of the tower location.
