first thank u
I got simcard slide under the battery & I did not find programs to run simcard after I"m insert it
So you inserted the SIM card, and now you want to connect your computer to the cell network, if I understand you correctly.
First you should make sure you have the latest drivers for your mobile broadband card; these should automatically install in Windows, but if they don't you can find them on Lenovo's website.
Once you've done that, read this article from Microsoft
; it should tell you how to get properly connected.
Hope this is helpful!
