SIM card reader

Making useful USB 2.0 multi-card readers even handier, this card can also read and write data to phone SIM cards. It comes with SIM editing software. Download your phonebook to your computer. If you lose your cell phone, you can store missing phone numbers in your new one. The US-made IMOMO SIM card+ Multi Card Reader is priced at US $19.

SIM card reader can be used to _________.
A. edit all the data in your computer
B. remove data in phone SIM cards specially
C. help restore your phonebook in a new cell phone.
D. transfer any file between an MP3 and a cell phone.

Which one is better? Why are the rest wrong according to the ad?

BTW: Making useful USB 2.0 multi-card readers even handier, this card can also read and write data to phone SIM cards.

The above sentence is quite confusing to me. Should I replace "this card reader" with "this card"?

Thanks.
