I have the Simcard reader installed in order to have always have it now on my 4 computers. Since I often safe and copy (SMS and phonebooks) the content of simcards I was looking for a USB tool to replace my ancient serial readers. Installation was simple and straightforward. After installing drivers and software I put each the card reader into a USB port to which each some time went to appear was the unit is ready for operation. At first I thought it should run a little - but every computer chewed initially some time around it; so I gave him time and at some point was always everything OK!
The included software is as simple as it is effective. All computers are easily able to read the SIM cards, edit and rewrite again! I've tried before some cheap versions of card readers, but this one is the only one you worked really easily! The money is well spent for me - I would buy the part at once!
