My signal bar has dropped to zero cannot call or recieve calls

Hi..Call Barring means restriction on the Phone.The restriction can be one way or two ways that is both incoming and outgoing calls.

In my micromax Q7 mobile all incoming calls are replied with this number is busy. Neither I locked nor barred the calls, knowingly or unknowingly. Please get a solution.

The @ represents pressing the "Send" key on your mobile

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.

Hi!

You need to remove or unset the phone contact filtering. That is on the phone call settings.

Hope it helps..

Thank you for reaching Fixya.

Please leave comments for further assistance.

Hi,
Please make sure your outgoing and incoming calls are not barred.
go to settings
go to call settings
go to call barring
and check the status of your outgoing and incoming calls.
There is also a line 1 and line 2 facility. Make sure you are using Line 1

Hope the above is helpful.

Thanks,
Kanu

This is probably due to a damaged mainboard. It happened in my sony K770i and im afraid its a write off. I had the same problem it was as if the imei had been blacklisted.

go to tools, settings, phone, call barring, voice call barring, outgoing calls and deactivate

I flashed and flexed the set but to no avail, tried a software update but no update was available from motorola. I then went to the Security settings of the set and restricted all outgoing calls and restricted all incoming calls except the phonebook entries. Then I dialed my mobile using a landline which was on my phonebook and my phone started recieving the calls, then after that I allowed all incoming and outgoing calls. This solved the problem. I believe it is sheer luck because I tried that step earlier on the same day but it gave no result.

Hey dude,
One thing, if ur nokia N95 is china mobile. U cannot access or have connection to internet.
If it is NOKIA branded, consult a mobile technician or ur SIM operator for GPRS settings.
