SIM and MicroSD Cards in Galaxy J3 and J7 2018
Although J3 and J7 (2018) have similar names and features, their main difference is their card trays. On both phones, this card slot holds your SIM and microSD cards, but they are set up a little differently. The J7 has a new slide-out tray on the side of the phone, whereas the J3's tray is behind the phone's back cover. Knowing how to properly insert and remove these trays is super important because they are essential to your phone. SIM cards give you access to your wireless service provider's mobile data network and MicroSD cards allow you to expand the storage on your phone. In other words, you definitely don't want to mess them up.
SIM cards are provided by your carrier or retailer where you purchased the phone.
MicroSD cards are optional and must be purchased separately.
