I hanve the problem that there are no network signals means there is no signal bar on the top corner of my screen in nokia 6681

In the top left hand side of the phone on the signal strength bars in there a red cross ? if so then please take the sim card out and put into another handset and see if it works in there and if it does it indicates that there is an issue with your nokia mobile phone however if it doesn't it means that the sim card has not been activated properly and so you will need to contact you network provider and give them the sim card number.

First Option:
Phone in the Other Sim and check the Phone Network Signal If Network Signal Problem not Solved So
Secend Option:
Your Phone Network IC Fault So Please change Network IC
And Network Signal Problem will Solved
if it is there isn't much you can do on this side of the network.
Contact your phone company.

Network provider sometimes caused this problem because of their system mulfunction or upgrade. With that sometimes we can call but texting unable to send or received, but sometimes a signal indicator is full but not connected to the network provider, it means a feak signal. My recomendation is to contact network provider hotline and tell your problem or replace simcard. If yuo totally cannot call and text then positive your fone has a signal problem and need repair on it. Good luck

3G simbol comes when we get rid of range,and if you want to get rid of that message goto settings>network>operator>network gsm only
thanks

Hi, since it is a nokia phone, and on the phone it has service signal bar showing on the screen of the phone, Just apply this codes #33#0000#( to cancel any beared calls(both in and out going calls and #002# ( to cancel any call divert on the phone.

NOTE: it will only work if the service signal bar on the phone the makes you know that there is service on your is full. If not, that means the phone network will be the problem which you will need to consult repairer.

Take care.

The simplest wifi detection software is already in Mac OS and is pretty easy to use. Open your System Preferences via your dock and then open the network connections icon. Then open your airport control. Look for the check box to put Airport control in the menu bar. After that, you can simply open the screen of your macbook and the antenna bars will show you available signal and if you click on the antenna icon (top right corner of screen), you can select the name of the available network... Pretty cool and you already own it!

Select Menu- go to settings -select network-change operator selection to manual your mobile will scan for the network and select the network and check the signal strength..If signal strength is still low contact your operator (customer service).

plz change signal ic
