I took the Free Upgrade Option from my Carrier.. Went with the Sony Xperia M4 Aqua.. My issue is the Sim Card , my previous Cellphone had a Micro Card.. The Sony is a Nano Card, instructions say to take scissors and trim it to fit.... From the Previous Cellphone to the Sony , the setup is totally different.. My Query is , Just how much to trim off and does the card then just slide in to the small slot ?? Help Appreciated , Cheers Thanks..
