Hello guys, sorry to bother you but I'm really desperate and I have not that much knowledge about phones (my one and only smartphone was the Iphone 3G and it stopped working a few days ago). I really need a new phone and I thought about the Iphone 6! I thought I have to buy a new unlocked phone to use it with my simcard (I have no actual plan, I'm on my mothers plan with a separated sim card). I have a sim card from at&t. Do you think I can buy a locked Iphone 6 (at&t) at it will work, even so I don't buy it together with a new plan? I really hope you can understand me, my english isn't that good, sorry. Altough I really need a phone as soon as possible.. I have no phone since a few days...) Thanks Nona!
