Hi there, I am very very interested in ordering the note 4 but I am very confused about choosing the correct sim card type.the phone I'm using now takes a dual micro sim, can I use that same sim card for the note 4? Would I have to use 2 sim cards for the note 4? And does a single sim have 4g? Reply:dual sim support dual 4G card work at same time.single sim support one 4G sim work.thanks...
