I bought a regular SIM and cut it down. Had never cut one before, so I downloaded some template (from a google search), got a pair of scissors, marked it, cut it, and then used my wife's nail file to finish the fit. It probably took a total of 5 minutes and worked perfectly. This was all before I became thoroughly discusted with ST (AT&T) and their daily throttling while downloading less than 100mg/day, and switched to a direct Tmo plan.
