MIDP applications don't have access to the SIM card through a standard API. I'd check whether your phone vendor provides a proprietary API for doing that.

Actually, JSR 177 is an attempt to standardize SIM access APIs. However, the progress is slowed by debates about licensing and whether to include crytpo APIs. You can check out the voting record to see what people have been arguing about. So, in short, the standard SIM API for CLDC is still a long way off. But like Lasse said, vendor specific APIs might be available for some devices.

Lasse & Michael,
Now i understand that i can not write MIDlet to update any info on SIM card. For that, i can use vendor specific API and program written using the API can be run from PC(thru Infrared port) to update the SIM card. Is my understanding correct?
Thanks and regards,
Murugesan
