Using Verizon EVDO with Windows Vista

I’m sure by now that a number of you have signed up for the Verizon BroadbandAccess EVDO service.  If you are a trail blazer and are part of the Windows Vista testing gang, you have probably noticed by now that Verizon’s connection software (VZAccess) doesn’t run under Windows Vista.  Never fear, there is a solution to this problem.

Creating an EVDO Dial-up Connection

  • Insert your EVDO modem card.  I am using the PC 5740.  Make sure you are doing this at home or in an office and Windows Vista networking via your homelan or office lan is already working.  The detection process needs to get the drivers from the Windows Vista update site.

EVDO modem detect

  • Click the yes button to search for the drivers.
  • Let the detection process complete and you’ll see the success result dialog box as indicated below.

EVDO modem installed

  • Go to the Network Center.  You can get to this a variety of ways, but Control Panel | Network Center works.
  • Click Setup a connection or network in the left hand list of tasks.
  • Click setup a dial-up connection as shown below

EVDO setup dialup1

  • Pick the modem from the list.  In my case, it’s the Curitel PC Card.  This will bring you to the next screenshot and allow for the other information we’ll enter.
  • Enter #777 as the phone number.
  • Enter a network name.
  • Check the box that lets other users use this network on your machine.  I use this for guest access on my machine.

EVDO setup dialup3

  • Click the Connect button and the new connection will be attempted.  You should see the success message similar to the dialog below.

EVDO setup dialup4

Happy surfing!!!  FYI, I also tested VPN connectivity across this to my corporate network.

VzwFor the Kyocera, KPC650,

  • Copy the Verizon VZaccess installer to your harddrive
  • Open properties, click the run in XPxp2 compat mode and run as admin
  • Install the software.
  • Once the install finishes
  • Insert the card and use network center to create a new dialup connection
  • If you are prompted for drivers look in program files\verizon wireless\vzaccess manager\drivers\650
  • Dial #777 – no username or password
  • You don’t need to use the VZaccess software
  • I have noticed sometimes when I wake the system and insert the card the system won’t see it.  If you just reboot with the card in it will work fine.

  • I typically try to avoid the VZAccess software whenever I can due to the special Venturi software likes to mangle the TCP-IP stack/helpers from time to time. Another blogger has a step by step instructions on avoiding the software.

    Basically, under

  • Awesome!!!  Thanks for the tip!

  • Great!  Do you have similar wisdom on how to get the Cisco VPN client to work with Vista?

  • This was a lifesaver!!!!

    You're the man!

  • Thanks for the tip.
    I have a problem though!
    I was successful once. The first time I installed vista, I was able to connect. After that all my "attempts to connect failed"
    I Installed a fresh copy of Vista (For the purpose of repatitioning my HD) I configured the card.... and everything went like a charm...but again the second ttempt failed.
    Do you guys have any idea what's going on?

  • Well, After toying arround with the settings, I desabled the Curitel PC Card Diagnostic Serial Port WDM under Ports. and I'mup and running again!!

  • FYI, I downloaded a different version of VZAccess Manager from  Version 5.6.1 is designed for the Blackberry RIM devices but since I already had the previous version of VZAccess installed with the PC 5740, it apparently just upgraded a few of the components and worked.

    I'm sure it's an unsupported configuration but what the heck, it's a beta operating system.

    When I connect, the status bar never changes from "Authenticating connection".  I sat there and watched it like a dummy for a few minutes then finally just tried things and viola, it was working.  It also doesn't update the status bar when you click the disconnect button.  So I just exit VZAccess when I am done.

    One other thing, Verizon warns that if you aren't using VZAccess, you won't get the benefit of the flat rate for unlimited usage and will be charged for minutes.  That hasn't been my experience, but I thought I would mention it.



  • Has anyone found 64 bit drivers for the Kyocera CDMA modem?


  • I too have been testing VZAccess by SmithMicro and their generic management tool for broadband connections. Neither work so I have set up my Kyocera card manually. My question for all is:
    How important is it that we have that management software? What about Verizon roaming updates, etc?

    Wondering in Houstin,

  • I don't know how important the VZAccess software is.  You would need to ask Verizon about that.  Verizon did tell me at one point that it was needed to prevent being billed per minute charges on the unlimited data plans, but my bill does not reflect any charges when I used my PC 5740 in the manner described above.

    I also don't have the card you are asking about, so I cannot test it.  Sorry.

  • One more piece of 3rd-party software that I don't need: VZAccess Manager. Keith's excellent post got...

  • PingBack from

  • Has anyone tested this with Vista RC1?

    This worked for me with earlier versions, but fails to connect with RC1 (build 5600)

  • Yes. In fact, I did some testing Thursday of this week because the billing for my account changed and so did the phone number.

    To be clear, I tested my PC5740 pcmcia card using the instructions above (the original post).  I have not installed and tested VZAccess.

  • As you'll recall, a few months ago I posted instructions on how to use the Verizon PC5740 pcmcia EVDO...
