call fails on IPHONE 4s

[Bellare]

I have recently bought Apple iPhone 4S and I am one of the lucky people to have this mobile phone. It is simply amazing. It runs on iOS 5. But I am little frustrated about this mobile. My call is failing several times. Many people cannot hear what I am talking and I figure out that I am unable to hear the person’s voice. What should I do?? Any help will be appreciated. Thanks in advance.

I think the problem is due to corrupted software. Check whether the software which is installed in your iPhone has corrupted or not. I will suggest you to reset your phone. After resetting the corrupted software will get deleted and it will repair your phone.

You should do the following process to solve your issue:

• Go to call settings>>select caller ID>>turn on caller ID should, those other 2 off and u have to check also if u can see your own number showing in Settings > Phone)
  
• Go to Settings >> General >> Network >> Cellular Data>>turn it off
  
• It will help to prevent any disturbance in connection and signal

Few months ago I purchased new factory unlocked Apple iPhone4S and I often get Call Failed message when try call. I have experienced that sometimes during a call; the call was dropped in between. It happened even when the signal was full. I have also experienced that message sending fails when I send messages. This is very annoying. Is there any solution for this??

I want to tell you that the problem is not in your iPhone. The main issue is in the service provider you are using. I will suggest you to contact your service provider as soon as possible and ask them about your issue. They will eventually solve your issue as soon as possible.
