Free Nokia 2610 with AT&T sim card(only to pay for the balance)

Nokia 2610 Cell Phone for AT&T, excellent condition, works perfectly. Comes with SIM card of the go phone plan, and the balance in the card is around $27(expires on Feb. 2, so you need to refill the card before that date or all the funds would be forfeited, $25 refill is effective for 90 days, the balance carries over to the new expiration date).
I am just asking for $20(the phone with the sim card is free), they are all yours.
Battery, home charger and user manual included. Email me if you are interested.

Just for your information, I bought the phone at walmart for $15, plus tax(so all the value is around $43, I am asking only $20).
The go phone plan is introduced at the website below: (It is especially suitable for short-term visit, because I just use it for emergent situation,most of the time I use internet, and the average cost is only $6 per month)
