SIM and microSD cards for your Galaxy phone
SIM cards give you access to your wireless service provider's mobile data network so you can make calls, send messages, and more. MicroSD cards, on the other hand, allow you to expand the storage on your phone so you have even more space to save your favorite moments.
Note: SIM cards are provided by your carrier or retailer where you purchased the phone. MicroSD cards are optional and must be purchased separately.
Insert the Nano SIM and microSD card for S7/Note8 or newer
Important: Be careful not to insert the ejector tool into the microphone hole also located at the top of your phone.
Inserting a Nano SIM and microSD card is really no sweat. Power off your phone and then insert the ejector tool that came with your phone into the hole on the SIM/microSD card tray. Next, you will want to push the tool until the tray pops out. Carefully line up your Nano SIM card with the smaller cutout on the tray, and then place the microSD card on the larger cutout on the same tray. Verify the cards are flush with the tray, and then insert the SIM/microSD tray back into the slot on your phone. Now, power on your phone and you’re good to go!
Note: Not all phone models support microSD cards.

Insert the ejector tool into the hole on the SIM/microSD card tray, and then push it until the tray pops out. Remove the Nano SIM and microSD card from the tray and then insert the SIM/microSD tray back into the slot.
