I'm sure that in any cell phone store in any country you will have no problem cutting the old SIM card with a special device, especially since there is nothing complicated about it. I just did not go anywhere and cut my old SIM card myself (according to a template). All you need for this is to have any new SIM card, just cut it out of paper to make a template for trimming. You can glue the template where you will trim the micro SIM card, but if you are afraid to get the glue on the chip, just attach the template to the SIM and trace it with a thin pencil or marker in the cut areas. It's best to cut out the new SIM with thin scissors. To avoid jagged edges on the plastic, try to trim each side in one motion.
