Connecting android tablet to inernet

[ray5thomas]

Can an at@t usb connect mercury(sierra wireless) be used to connect a 7" android wm8650 to the internet? If so, please advise as to how. Is a different sim card needed?

I too am unable to stay connected to the Internet due to roaming IP address. Help. I have an Acer Iconia 500 Android Tablet.
