Welcome to Vodafone Community
Firstly, welcome to the eForum. Thanks for joining. As you're new make sure to visit the Vodafone Help Centre. It's something we use here and I always recommend it to new members as it's full of instant hints and tips on most Vodafone products and services.
The best way to get this working will be to fully uninstall and reinstall the Vodafone Software. You mentioned you reinstalled the device a few times but there are a few extra steps which will help further.
1 - Go to Start - Control Panel - Programs - Remove the Vodafone Mobile Connect software.
2 - Reboot and go back to - Control Panel - Programs - and check that there are no further instances of the Vodafone software in there (including Vodafone Mobile Connect, VMC, VMC Lite, Vodafone Runtime components etc)
3 - Go back to Control Panel and click on Phones and modems. (If you can't see it, make sure you're in classic view in Control Panel) Click on the modems tab and remove and remove any entries of HUAWEI modems in there (unless you have another that you use)
4 - Go to Start - Connect To. In here right click and delete any Vodafone dial up connections.
5 - Reboot and wait for a few minutes. Now plug in the modem. If it doesn't start automatically after a minute or so, go to Start - Computer - Right click on the modem and click Autorun.
I'm sure this will get you up and running, but we're here if you need any more help.
Thanks for coming back to us here and I'm sorry to hear that this has not resolved things for you.
I have managed to find quite an indepth discussion regarding the same problem on another thread on our forum.
Have a peak as it suggests a few ways around this and potential fixes. RAS Error 720
Let me know how you get on and if you have any more questions please let me know and we'll be happy to help
I think it might be time to send the modem for repair! If you've tried it on another machine with the same results, I think it's safe to say something must be wrong hardware wise.
Let us know how you get on
Hi Jon , Thanks for your help after I checked some driver settings on my XP machine I managed to get the device to work run on my PC so I'm prettey sure it's not the device thats at fault however when running it on vista Home edition I still continue to get the same error message RAS error 720, I've read the other forum post suggested by wayne earlier and a few other posts on this forum where people seam to be having the same problem and in most cases it seams theres an issue between Windows Vista and the Vodaphone LITE software , Is there a later version of the software available?
I hope you can help the device was working without a problem it suddenly started producing this message I've even re installed the OS on my machine to see if there was some sort of microsoft update that may have been causing the problem but I continue to get the same error message.
Please Help me
Can you shed some light as to what you did to your driver settings as I am getting the same error code 720. My details are;
Laptop Toshiba Satellite A100
Operating System Windows XP Home Edition Version 2002 Service Pack 3
Vodafone Mobile Connect Model K3520
Appreciate any help on this as I have spent the last 2 days on the phone and all they seem to advise is uninstal and reinstal which has not worked.
