    Samaung I900 Dropping Calls and not letting me send text messages

    Hello i have a Samsung Omnia 16gb which i bought of AvForums roughly 2 months ago. It was working perfectly until today when it started to give me problems. As of today every time i try to make a phone call it says "cannot complete the call. The signal may be unavailable or the phone number may not be valid. Verify the number or try again later. " and it won't let me send text Messages either, as it just will not send. By the way i have tried 3 different sim cards inside it still having the same problem. Please help guys and i contacted Samsung they said that they will need a receipt from the retailer to validate the warranty, is there any way in which Samsung will repair the phone without the receipt. Thanks!! Please help

    It was registered on the Immobilsie website,will that help me get the abr removed from the handset or get my money back. Thanks

    If its blacklisted only the registered owner (as listed on the network) can get it unblacklisted.
    If anyone could call and get the bar lifted the whole system would be pointless...

    If you contact the police and the phones been reported stolen they'll take the phone from you and return it to either the owner or, if the insurance has paid out, the insurance company. Not a lot of help to you, sorry. . .

    It dose sound on the surface like you've been sold a pup. . .

    Is there any way to remove the bar from the phone. (like flashing)? Please help guys. thanks

    The phones send it's IMEI to the network every time it switches on. All the networks have a blacklist of IMEI's listed on their servers. If the IMEI's on the blacklist the network won't allow it access. So flashing the phone does no good as it's the networks computers blocking it not anything in the phone...

    In the old days you could change the IMIE, but today that's... A: Very illegal and B: almost impossible on most modern handsets...

    Do I take the guy you got the phone from is being less than helpful ?

    hi mate thanks for your help once again. It looks like I will be given a refund now.just out of intrest is the bar sent through your sim card. As a couple of my friends said if I had taken the sim out immediately then the phone would not have been blacklisted. Thanks

    No, nothing to do with the sim.
    The phone has a built in serial number (a 14 digit IMEI, sorry if you know all this already !). The IMEI tell the network stuff about the phone, like the model number etc. Each phones IMEI is, obviously, different.

    When the network blacklists the phone they place the IMEI in a file on the server. Each time the phone comes on it sends it's IMEI number to the network (along with a lot of other info). If the phones blacklisted the server just refuses to allow it to access any services.

    The networks have an interconnect for stolen phones so that every one is blacklisted on every UK network as soon as it's reported stolen on any one of them.

    So taking the sim out would have had no effect at all, the bar isn't sent to the phone as such if fact no bars are.

    I think what you friends are thinking about is when we restrict an acc for stuff like none payment. The acc is linked to the sim, so the bar can be partial (lets through incoming calls and txt's but stops all out going) or a full bar (which stops all traffic in and out). If you took the sim out and stuck a different one in, the phone would work just fine as this bar is linked to the sim.

    Hope that helps ? If you'd like more info let me know...
