Andrey,
AT&T offers that plan. It's called the Family Plan, and it is actually $24.95 per month, with 60 minutes of outside calling. This is the lowest priced plan in the Family Plan, and it does include voice mail (with no charge or minute use to access it from your cel phone), caller i.d., call waiting, call forwarding (watch it on this one. You are bill per minute if you use call forwarding!), and three way calling. Also, for everyone looking to get a cel phone, always check at the start of the month. This is when the companies usually roll out their new promos.
