This is a small unit, shaped like a USB flash drive. I comes in a plastic bag with the CD-Rom containing the software and a brief written instruction sheet. Set up of the software was a breeze- 2 minutes at most.
The unit accepts the SIM card slotted into one side of it. I followed the diagram in the printed instructions, got it wrong and found that if you do it the opposite way round to the diagram, it works fine. You then put the device into any available USB port. This brings up the software. Now here, there is a slight criticism-the instructions in the software are written in less than adequate English and take a second or two to figure out.
You can then back up your SIM to a file of your choosing on the PC, copy one SIM to another, write a saved file of SIM contents back to a SIM and other useful actions. Read and write speeds are impressive.
All-in-all, an effective piece of equipment at a very low price.
