Depending on your Phone you may be able to buy a data cable, or even better you may already have one with your phone purchase, along with some software. if you do install and set this up.
Failing this, purchase a Mobile Sim reader, you can plug this into your PC, and it reads the SIM Data, to allow you to modify it, and back it up, so if you lose it, you can simply insert the new SIM and write the backup to it.
