Try disabling 3G to see if thats the cause, if so request a new sim card. Menu> Settings > Connectivity > Network > Network mode - set to GSM.

If that doesn't help try the following reset codes, if the first one doesn't solve the problem try the second. The first code will just reset your settings. The second will reset everything and wipe all of your data. Be sure to backup before using either of them.

Enter these like dialing a number:

Reset to factory defaults (*#7780#) : Restores settings but preserves user data (photos, 3rd party apps etc).

Reset (*#7370#) : This reformats completely the C: drive. All applications and files stored on this drive will be lost and clean default files will be rewritten.

If after these codes you still have the problem you will need to contact vodafone as it may be a sim card or hardware fault.

My phone keeps fading off and won't switch on, cuts off in mid-text, doesn't ring, goes straight to voice mail and the phone is only a year old. Screen constantly goes blank. Help!

Missing calls on your iPhone? Or finding that your iPhone calls go directly to voicemail, and don't know why? You're not alone.
In this article we discuss some simple issues that may be causing calls to be diverted, and explain how to fix them. Read next: How to manage voicemail on iPhone
Check for iOS updates This is a double-edged sword. It's possible that a recent update to iOS has caused the problem (but if so, it should be patched soon); it's also possible that an update will fix it.
When Apple updates iOS it's inevitable that some things will go wrong. Most of these should be picked up in the beta. but a few will slip through to be patched at a later date.
When iOS 7 came out back in 2013, for example, some iPhones suddenly found that incoming calls were being directly transferred to voicemail. The option has since been disabled by default.
If you've noticed the voicemail problem since updating iOS, there's a good chance that the two things are related. Check for any new updates since then, which are likely to include a patch. Read more:
Do Not Disturb mode If the problem persists, Do Not Disturb mode may be the issue. Perhaps you turned it on by mistake, or turned it on and then forgotten about it. It may even have been switched on against your wishes by a glitch in iOS.
You can tell quite easily if you've got Do Not Disturb switched on, because there will be a crescent moon icon in the top right of the iPhone's status bar, next to the Bluetooth and battery icons.
When Do Not Disturb is enabled, calls and alerts that arrive are silenced: that's the reason your calls are being diverted before you have a chance to answer them.
The quickest way to turn off Do Not Disturb is via the Control Centre. Swipe up from the bottom of the screen to bring this up.

The Do Not Disturb icon is in the top row: it's the crescent moon. Tap this and it will turn from purple (switched on) to grey (switched off).
In iOS 11, which at time of writing is available in beta and comes out officially in autumn 2017, Control Centre looks a bit different, and the precise controls shown are customisable - but you'll always see the Do Not Disturb toggle. It's the same as before: a crescent moon.
Alternatively (although more slowly), you can turn it off via the Settings app. Open the Settings app and in the second batch of options underneath Notifications and Control Centre, you'll see a purple icon with that crescent moon and the words Do Not Disturb.
Click on that. Move the slider on Manual so that it's off - so there's no green on the slider.
How do I stop my iPhone going to voicemail after just three rings? This is a slightly different problem. Your voicemail isn't controlled by the iPhone itself, but by your network provider, and you have to adjust these settings by dialling your network and using a phone option.
First of all, check there isn't something weird going on with your network settings. Go to Settings > General > Reset Network Settings, then enter your passcode. This will ensure that you have the right settings for your network.
Whether you can change the length of time that the phone rings before going to voicemail depends on the network provider. Some, like Vodafone, enable you to change this using their automated system. Others require you to call up, or the amount is fixed.


Vodafone enables you to choose the length of time a phone rings before going to voicemail. According to the Vodafone instructions:
  • Enter **61*121*11*[Number of seconds]#
Then enter the number of seconds you'd like your phone to ring for (it has to be between 5 and 30 and a multiple of 5), followed by #.
For example, if you want to set if for 25 seconds, you'd enter **61*121*11*25#, then press call.
Vodafone will send you a text letting you know if this has worked.


To adjust voicemail settings (including turning voicemail on or off) you need to call three on 333.
To turn off VoiceMail on the Three network, dial "333" and tap the "Keypad" in the Phone app. Press the the following buttons
  • 2
  • 1
  • 2
  • 3
  • 1
  • 1
You should get a text from Three stating that you have successfully turned off voicemail. To turn it on again go through the steps but change the last entry to "2


O2 has a direct line to turning voicemail on and off. Just dial the following numbers direct from your phone.
  • Turn voicemail off: 1210
  • Turn voicemail on: 1750

It sounds like the app may need to be updated for iOS 7,
The Lockbox website says it's compatible on iOS 5.1 and above. but i cant confirm if its updated for the new iOS yet.
it shows a new version 1.3
check your updates and see if it updates today.

Hi. i need a no. to restart my phone ( gt-e1080t samsung) because there is no signal.. or any solution..

Hello there,

Try putting in another sim card to isolate the problem whether its a phone or network problem. If putting in another sim still gives you a no signal, it might help if you restore the phone to its original settings. Just dial *2767*3855# and the phone will restart itself.

Tell me how this goes. Thank you for using FixYa.

Fax Machine not picking up incoming faxes...

If this is on a network your network tech needs to set up your machine through one of the routers.
If the machine was pluged into the phone socet direct, there would be no problem. The phone will ring constantly, until you plug the phone to the machine.
If the machine does not answer the phone, then the problem maybe in the machines confguration for auto answer, or a modem board not working.

But on a network, the computer is trying to find the signal, but can't because it cannot find the machines signal.
This problem is in the network side. Check with your network specialist.

Connection error

Hi there, 
Connection error usually is because you set some restriction to make or receiv a call. However, this setting can also be done by the network provider.
And since you said you got no signal, means that your SIM card can not finish registering to the network, which normally means that your network provider is blocking your card. Same thing happen to pre-paid card which no longer in active period and already pass grace period.
I suggest you call the network provider, or come to their support center for solution.

Sim registration failed

most of this nokia phone(the old ones) do often experience such problem due to it's constant falling on the ground.
in such cases after restarting the phone the problem should be corrected for a while...............using a NEW sim card and practically the one of a network with the strongest signal does in most cases rectifies the problem a bit.
all the same i would ask you to send it to a phone technician for more help.
good luck
