brand new samsung galaxy s3------colour white as seen on t/v the latest model, reason for sale was got as an upgrade for my wife but im afraid it is to advanced for her. it is two days hold as you would expect in mint condition. it is locked to t/mobile. i would keep the phone but i have a iphone myself. there is no micro sim as it will be used in another phone. this phone is on sale for 599 on pay as you go. so this is a bargin at the price. i will take offers on the phone please contact me with your offer. thank you for looking
