My main use is reading SIM card for backup. No cd with the product, I had to go fishing at the drivers on the website of Connectland. Then had I found the software to read the SIM card on the same site. Once this is installed properly under XP, my two SIM cards (Virgin and Free) are not recognized (not present) and the soft Connectland plant. After trying several other SOFT, only SimCardExplorer managed to recognize me and read the 2 cards without worries. Unfortunately no backup option on PC. In short the galley. Not yet developed.
