JOESHAB8 years ago000In CH I use the network "Das Abo" with a SIM card which fits my IPhone 4s. In the U.S.A. I use a SIM card AT&T for my Iphone 6. Will both SIM cards work in the Samsung Galaxy A7 Dual SIM?Skyyy6 years ago000It should work just fine.CommentAnonymous8 years ago000The Iphone 4s still uses a Micro-Sim, the A7 and the Iphone 6 use a Nano-sim. You'll have to cut/reduce the size of your Ip4s Sim.Comment
