Inserting the sim card on your galaxy s6 is pretty easy, but can be difficult if you’ve never had to do it before. First of all with the galaxy s6 and galaxy s6 edge being very similar when it comes to the sim card they are not the same. The sim card slot is located on the side of the phone, and can be opened with a small pin. You just need to push the pin in and the sim card tray will pop up. Once its popped out you just need to pry it open to take out the tray.
Once you have it popped out inserting your sim card into your galaxy s6 is pretty straight forward. You do need to be aware however that the galaxy s6 and galaxy s6 edge have different sim card sizes. This was a lesson I had learned when trying to switch the sim card into the galaxy s6 edge. It doesn’t really make sense to me that they both have different sim card sizes, but just keep that in mind when your getting ready to insert your sim card into your galaxy s6.
