CAN'T CONNECT INTERNET USING USB BROADBAND TO LAPTOP DELL STUDIO 15

The SIM card is for a mobile data plan. If you go to say...AT&T and purchase a wireless data plan on the cellular network and insert the sim in the back of your laptop you will have internet access on the cellular network.

Good Luck, and do rate the solution if got help

Hello, Lyn.

On the left side of your laptop, you'll find a wireless on/off switch. See if that switch was turned off.

Hopefully, that will help.

P.S. I didn't grow up in the computer age, either.

install your usb broadban kit on your laptop, now its reaady to use...

you need either a wireless usb adapter... and a wireless router or a usb router and a usb cable...

It's quite cool and fast as described, I used the Vodafone Mobile connect HSDPA and I can confirm the good performance.
One serious issue are the costs, as you pay for the downloaded MB once you exceed your free data limit,
Not sure if you want to use it privately, then you need to monitor the amount of downloaded data closely otherwise you will be poor very soon :-). Check at the Vodafone Home page the costs.

you need the DW5530, it will work with the sim card slot you have. I beleave it goes inside the pc into a mini-card slot ( mini pci express not into a usb port )

here you have a picture of it
