nextel 7100i will only read sim cards that are yellow on one side....7520 with the new software will read the old condor sim cards....which are white with a gray logo on it...

ok back on topic
if you can get an exel spread sheet of the sim card numbers you can import those into outlook and then sync your blackberry...

that is the only other way I know to do it...and I have a bes so I dont know if that matters or not either...
