    I am in UMTS/HSDPA areas all the time here in NYC and never drop calls. I know sometimes people drop calls when they are on 3G and cross into an EDGE/GPRS area, but I havent heard of people having lots of dropped calls in 3G areas, sorry.

    It could be your phone. How old is it, perhaps you can return it and get a new one. I have had my 750 for a few months already.

    I sometimes get dropped calls when transitioning from a weak UMTS connection to a strong EDGE connection. One option is to set the phone band to GSM/EDGE only or HSDPA/UMTS only. While there are certain drawbacks, I am mostly in a UMTS area so I set it to UMTS only unless I know I will be travelling to an EDGE only coverage area.

    Could it be your cheek hitting the screen and hanging up the call? I disabled my screen while on a call. No dropped calls as of yet.

    Try getting a replacement.
    But you can lock it to GSM mode.
    Just to to start>settings>phone>Services> and select "Band Selection"
    Change it from "Auto" to just "GSM"

    Thats what I did and my battery life, and peace of mind, have doubled. UMTS is way too fluctuative for my taste. 4 bars drops to 1 in a heartbeat sometimes.

    I am in a fringe area here at work though, literally. If I want 3G I have to put my phone on the right window. If I move 2 feet to the left I drop to GSM...

    I too am in the Atlanta area with a Cingular 750. I use screen lock to avoid the cheek presses. I have also experienced exponentially more dropped calls with my 750 than any other of my past Cingular phones. Maybe the Atlanta area UMTS is not very stable yet. That is the only conclusion I can draw since other 750 users in other areas are having success.

    I'm on Cingular network in Chicago, and I rarely get dropped calls. I used to get a lot of them when I had the 650

    I have been experiencing dropped calls too. The thing is that I am in Honolulu, which does not have UMTS yet.

    experiencing a bunch of dropped calls in the D.C. area - convinced its UMTS to Edge.

    I have given up on the 750...I drop no less than 10 calls a day! I have gone to an old Samsung for voice but I am still using my 750 for data.

    The phone portion of the 750 is for &^%$$$$,!

    I am in Atlanta..mainly UMTS. It seems to drop strong signals all the time...the network sux.

    Does anyone know if the voice aspect of the network will still work, even if there is not "U" coverage?

    I get dropped calls and am thinking to try setting the band to 3G only, however, I have noticed that sometimes the phone goes from "U" to "G". In these cases, assuming I make the above change, I understand data won't work, but does that mean voice calls won't work either?

    Yes. If you lock it to UMTS, it won't 'fall back' to GSM.
    Since both calls and data go over UMTS -OR- GSM, when you don't have UMTS coverage, and it's locked to UMTS, your phone will go to to "no service" and not find 3G (UMTS.) It's an either/OR situation where your phone is using all one or the other.

    For people having problems with dropped calls. Log in to your account a wireless.att.com and select add/manage features. Check to make sure "UMTS Compatible" is a feature listed.
    If it's not, call up AT&T and tell them your using a Treo 750 and make sure it's set up for 3G. I suspect this COULD have an effect on this.
    I suspect this one setting tells the phone to scan for GSM or UMTS networks while on the opposite network so it's always ready to switch over. Other wise the phone is caught off guard and has to find it after you lose service.

    Just a though. I'm not sure if it'll work.

    How do you know what network your WM 750 is connected to at any one time?
