    Question Unable to make or receive calls.

    Advertisement



    I have a O2 Blackberry 8800 that was baught for me as a gift a few months ago from ebay i think. The phone arrived boxed and sealed so i knew it was brand new. The phone worked ok for a month or so untill the device rejected any sim inserted. I was told the phone needed unlocking so i had it unlocked and the device accepted my Vodaphone sim and seemed to register ok but i cannot make or receive calls. If i try to make a call it just cuts off and the same if you try to phone it.The weird thing is that the network registers ok and i can send and receive sms messages with it. I have checked with Vodaphone and they tell me the phone is not stolen, locked or blacklisted. Is there anything i need to enable or any thing i need to change settings wise?

    Re: Unable to make or receive calls.

    I am sure that others will give you better advice and things to try but here is something that you can try - you must be getting pretty desparate with it
    - remove the battery
    - remove the SIM
    - replace the battery (without the SIM)
    - switch on ( the unit should say, No Sim or words to that affect)
    - replace SIM and battery and see if this now works.
    If not then try simply removing the battery for about 20 minutes. Replace it, switch on and see if it then comes up okay.

    Hi, tried that but the same happens. I've had a look in the call history and the error details are as follows:

    *NUMBER*
    Type: Place Call
    Error : Authorization Failure

    Re: Unable to make or receive calls.

    sounds like a network authentication issue. i would get tech support on line and have your account setup reviewed.

    if you volunteer that the issue might be with your phone- they wont look any further than your phone for the origin of the issue.

    You may have incoming and outgoing calls barred by your service provider.

    What happens when you try making a call with your SIM card inserted into another handset?

    thats what an authentication isssue is.

    the carrier will connect the call and then authenticate it. if authentication fails becuase voice services are not provisioned correctly- the call then gets dropped.
