How do i replace a iphone 4 simcard reader. I am quiet good at soldering so that’s not a problem just need to guidance as in videos as it my first time doing this kind.

akshay patel, take a look at this video. as well as this one. It will show you all the solder joints and explains it well. Not an easy task but doable. the reader itself is available at places like this. Hope this helps, good luck.

Hi old turkey, this part is missing will this be the cause, does this also cause not sim issue
