    I have a Blackberry Curve 8520. I noticed that the signal changed, from EDGE/GPRS to GSM. I tried battery pulls, OS reinstall and wipe handheld. I even change sim cards but nothing change.

    Can anyone help me?

    Thanks

    EDGE and GPRS are all GSM signals. Looks like your just switching between signal strength.

    It was solved by his network, there is nothing he could do at his end. This problem is caused by provider side hardware issues or poor reception.

    That is what is getting me confused. I have the same problem, and how is it possible that I insert my SIM card into my wifes same phone and it works normally???

    I had the problem with an 8520 and o2 UK carrier. Went from EDGE/GPRS to constant GSM, no matter where I was my signal was always full but GSM. Because of that I couldn't use my FB/Twitter apps properly and use BB App World etc.

    So I went down to the local o2 shop and had a moan and they eas saying it was likely my mobile, but I said it wasn't and it could be a faulty sim. So I had them give me a sim replacement and since then my signals always EDGE/GPRS. Never been GSM since.

    Hope this helps.

    Try this:

    Go to Manage Connections.

    >Mobile Network Options

    >Network Selection Mode: MANUAL

    >Choose Available Networks

    From here, choose any other Networks. (Other than the one you are currently using). I recommend choosing a Network which you think has the best signal/coverage. Choose other network for a while (you will get SOS). Leave it for a few seconds. After that, choose your Network again.

    Hope this helps.
