    I still have the old ATT (with the blue SIM card) I am currently using a Treo 680. I would like to get a Treo 700. My question is will I get 3G internet on a unlocked 750 when using my old ATT SIM card? Or do I really have to migrate over to the new ATT? I am getting a good rate on my current plan I really do not want to migrate.

    I assume you meant to say 750 in the text.

    Some people are reporting that they are losing 3G access using ATTWS SIMs, and that they have been told that the "blue" plans will be phased out. It still works for others.

    I would say that you should try it first and see what happens.

    Yes, I totally meant 750 NOT 700..

    How do I know if it is 3G or Edge when I put my SIM card in?

    Assuming you are in a 3G area, you will see U (or 3G or H in WM6) at the top of the display. If EDGE, G (or E if WM6).

    Here is my blue story I am always happy to share...

    Former AT&T Windows Mobile Connections Settiongs

    http://discussion.treocentral.com/sh...ap.mymmode.com

    AT&T Sim & Treo 750

    Well it finnaly happened. I needed a replacement SIM card because all inbound calls went to voicemail. Outbound was ok.

    After turning down several reps who wanted me to upgrade to the new and great 3g cingular orange. I received my replacement blue and white AT&T sim card. After activation I can now make and receive calls.

    But, no text, no internet and no email, ARGGGG!

    After many hours on the phone with a very nice and knowledgeable tec I was told this is not a supported device and service could not be provided. So I pulled out my Nokia 6201 and said ok lets support this, this incase.

    Anyway lots of pain here are the steps and settings I used to get my internet and email.

    Settings > Connections > Connections > Manage Existing Connections

    This should take you to the MyIsp Modem Screen. There was a preloaded ATT connection that I think was created using the SIM card. I will not go into the number of settings I tried with this that did not work. In the end I found out I could delete this modem connection by pressing on the black dot.

    Next touch new for a new modem connection

    Name: ATT BLUE (your choice)
    Modem: Cellular Line (GPRS, 3G)
    NEXT

    Access Point: proxy (this begins setting that differ from my last SIM card)
    NEXT

    User Name: Null or Empty
    Password: Null or Empty
    Domain: Null or Empty
    ADVANCED

    Use Server-Assigned IP Address: Yes
    Use IP Header Compression: Yes
    All Others: No

    SERVERS TAB
    Use Server-Assigned Address: Yes
    OK

    FINISH
    Press & Hold the Modem connection screen and select connect.

    Also

    Settings > Connections > Connections > Manage Existing Connections
    ADVANCED TAB

    SELECT NETWORKS
    EDIT/UPDATE 04/12/07

    Programs that automatically connect to the internet should connect using:
    My ISP

    Programs that automatically connect to a private network should connect using:
    My Work Network

    Edit > Proxy Settings

    This network connects to the internet: Yes
    This network uses a proxy server to connect to the internet: Yes
    ADVANCED

    HTTP:
    Server: wap.mymmode.com
    Port:8080
    Username, Password, Domain: Null or blank
    OK

    SOCKS:
    Server: localhost
    Port: 1080
    Type: Socks 4
    OK
    OK
    OK
    OK
    OK
    OK

    I hope this helps.

    Now on to my current problem. I can receive text messages but I can not send theme. Calling all textors, HELP! The rep asked me to change the SMS message service center number?

    Regards
