This phone is an upgrade to an old Nokia. We wanted to keep the same T-Mobile pre-paid plan we had and this seems to be the better of the two phones available. This phone is very basic with larger keys than the Nokia and a larger LCD; plus the clamshell design eliminates any chance of any butt-dialing. We also love the T-Mobile pre-paid plan since we don't do a lot of talking. You can roll over all your minutes for one year, once you reach the "Gold" level--after $100 of minutes purchased. This plan has cost us only about $15/YEAR!! when you add just a few minutes per year and the rest rolls over. If you talk less than 1000 minutes/year then this is the plan for you.
