Hi friend. You have to check the vcc line which hace between 1.8v - 3v on board
In some occasions the SIM reader used a trigger that indicate to the phone that a SIM card is inserted. you have to check the capacitor related. ![[Imagen: 262720a8c39c4c6cad5d6cd9995314ae.jpg]](http://uploads.tapatalk-cdn.com/20160826/262720a8c39c4c6cad5d6cd9995314ae.jpg) Enviado desde Samsung S7 con Tapatalk
