*****Is there a way to clear the SIM card for a Nextel i830 cell phone?*****?

If so, please tell me! Thank you very much! 10 points to the first person who tells me how to do it! I would like to not have to manually clear everything, but I will if I have to. Just please tell me if there is a simpler way. THANKS SO MUCH!!!!!!!!!!!*****Is there a way to clear the SIM card for a Nextel i830 cell phone?*****?
There is another way, but it will reset ALL of the settings on the phone. Go to the Menu, then Settings, then Advanced, then Reset Defaults, then select Reset All. This will reset all of the settings on the phone to the factory default, and it will also erase all of the contacts from the sim card.*****Is there a way to clear the SIM card for a Nextel i830 cell phone?*****?
