    if you want to change your OS, scroll up and hit the BlackBerry Help link, there is all the resources you need within the help section.

    maybe also call your carrier to make sure they arent doing tower maintenance or repair in your area.

    Upgrading to a newer OS doesn't help

    Having a similar issue on my 9900. I live in Toronto, Canada and on Rogers network. Just an hour or two ago I noticed my bbm wasn't going thru so I check my signal and it was sitting on SOS. So I turn of network and turn it back on, no use. Tried turning automatic network selection to Manual and after searching for list of network only found Bell and Telus but not Rogers. Also on a side note when I first checked network it was sitting on Telus.

    Now this is maybe the second time I've seen it happen on the same day and at first I was at home and 2nd at work. Just to let you know before hand I have excellent coverage at both places with Rogers on this and other phones.

    I'm on a hybrid of .545 and .580 which is so called the "best and most stable" of them all.

    The only thing that fixes this is a batt pull.

    buddy switch to only 2G mode and if possible get rid of bsnl and also update your OS to the latest one. search the forum on how upgrade your OS, it will definitely solve problem. Blackberries are great devices but they do not come with good OS in the beginning, they get up to the mark gradually, you will love your 9900 once the software glitches are soughted out after the OS upgrade
