is it possible....?

So over the past few weeks ive droven into some documentation looking for some hint that this might be possible.

So, you got yourself two 3g modems, one though the mpcie and the other through the usb. Would it be possible to use either of these devices to connect to the cellphone towers, then use the other one as a 3g access point? In effect acting like a super configurable cellphone booster?

maybe im just not using the right keywords, but i cant seem to find any sort of documentation about this topic.

3G cards usually don’t support such functionality, unless you know some that do?
