Novatel Merlin U630
After upgrading to Vista a while back I have not been able to use my O2 3G/GPRS card at all. Not really an issue, as I use it rarely. However it’s been niggling at me, so I decided to research it and get it working.
First off, you need to get the drivers for Vista to actually see the card. These where a right royal pain to locate, but I did in the end (download them here), the drivers here are the latest I could find, and work for me, they are from the Vodafone card, but that does not matter.
Pop the card into your laptop, the auto device detect will come up, but not find drivers. After Vista has faffed about just launch device manager, locate the unknown devices and install the driver above (use the Primary and Secondary drivers inf files).
Vista will assign the two modems (GPRS/UMTS) a com port each, mine were 8 and 9, but yours may be different.
Now download the latest MWConn from www.mwconn.com, launch it up and say no (puts it in English), then yes to creating the INI and extra EXE’s.
Now open the INI file up in notepad, and add the com ports into line 08 (mine is 08 COM=COM8;COM9) put your SIM Card pin in 09 (it will be encrypted next run), I left 10 blank, and then put the APN information into 11 (for O2 it’s mobile.o2.co.uk).
Launch the UMTSGPRS.exe file and it should say it needs a connection called Internet, say yes to creating it. Now it should all work nicely.
Not the O2 software (thankfully) but it works just great.
Thanks to Markus Weber for the great app. I highly recommend donating to him.

I’m not sure, and unfortunatly dont have a 530 to test with. The software will work fine, it’s the drivers I am not sure about.
The two cards it knows of in the inf are
nwDevice,PCMCIA\NOVATEL_WIRELESS-MERLIN_UMTS_MODEM-D022
nwDevice,PCMCIA\NOVATEL_WIRELESS-MERLIN_UMTS_MODEM-29E4
Download em and have a go…. can only not work
Are you able to use another network provider’s sim with the Merlin U630 O2 card?
It works fine with my T-Mobile sim, so yeah, should be ok.
i have tried many times but is not creating the file ,ini, .exe and so on.. any help?
Make sure you right click it and run as an administrator.

you can use this installer… working good on my Vista. This program include driver and dialer too.
H4NTU, that works great, and I highly recomend anyone that needs VISTA to work with the DataCard to use the MLGeneric stuff.
The only thing that needs configuring is the settings for the app, add the APN settings into the profile manager (apn=mobile.o2.co.uk, user=mobileweb, passsword=password)
Then make sure the system is set to use Automatic in the network selection.
Job done
Just have to say thanks to everyone here for your info, i now have my u530 working in vista using a combination of the german t-mobile device drivers (only ones i could find that worked) , the u630 drivers and mwconn.
Works great!
