Why nokia2730c shows network busy when calls - Nokia 2730 Cell Phone

unplug all the phones in the house, or go out to the NID (network interface device) on the outside and disconnect the "line" from the "network". It should have a standard modular plug. You should be able to plug a regular phone into that jack and see if the line has cleared. Chances are there's a phone in the house that's partially off-hook.

rest phone and chage the network msger number

Get the unlocking code for your nokia from your network provider. After that you may follow the instructions at http://www.mobileunlockguide.com/ .It helps to unlock your mobile easily.

not enough memory every i watch video in my nokia2730c and every i play a music i want it to be solved.

Since the network 'shows' busy, it could actually mean that the network is jammed. This may allow text messages, but not calls. The problem is with the network and not your phone.
Contact your mobile service operators to know what the issue is. They could be working on the system. But if they are not, I'm sure would able to restore full network so you can make and receive calls.

Please do let me know if this helps.
Have a lovely day.

If its still showins as a busy when the phones plugged in at the NId ( the box outside) then the trouble is showing towards the telco . Call your local provider for repair.

HI,
Nokia 6111 and Nokia 6300 are the ultimate phones and I like it very much.
SOLUTION:
1.Go to "menu". 2.Then select "settings" by scrolling down. 3.Inside "settings" menu, go to "call settings". 4.Inside call settings we can see various options to select that contains reject/show busy/divert.we can choose any one from them.
SOME TRICKS: Hiding your Mobile/ Cellphone Number
1.Go to: Menu > Tools > Settings > Call > Send My Caller ID >
"'Yes', 'No' or 'Set By Network'" to follow the default settings of your home network.
It works only with very few network who provide you facility of “Private Number”
