I have my Nokias 3650 and N-Gage, but wanted a simple phone to let my mom use when I'm not using my line. I've been with T-Mobile for awhile, so I'm getting the Nokia 6010 free after $20 rebate. I asked the rep if I'd have to pay extra for a sim card, but she assured me that I didn't. She then told me to call as soon as the phone arrives to get it activated. Now, would it be possible to let my mom have the phone so that she could make calls on my account whille I'm not using it? I don't want to kick out extra $$$ for a 'Family Plan' because I don't use alot of minutes.

Also, when I picked up my N-Gage a few weeks ago, it had the sim card in the box. Is it useless, or can I save numbers on it like a backup?

Thanks!
