Think mobile is offering the Nokia 1800, Samsung E1310 or Samsung E2120 for $72 over 6 months $0 upfront. This is a cost of $12 a month which includes $24 of total value a month, if the Think Simple 12 Plus plan is selected. So for $72, you get a phone and $144 worth of calls or texts for 6 months. This is a very good deal considering the Nokia 1800 costs $30 on virgin or vodafone prepaid (the $1 deal) of which credit expires monthly so the cost on virgin mobile for the prepaid option if one $19 recharge a month is bought over 6 months is $30 (cost of phone plus intitial recharge) + $95 (5 $19 recharges) = $125. Also, the Samsung E2120 costs min. $50 on shopbot and the E1310 min costs $55 on shopbot. Think Mobile uses the Telstra GSM network.
