How to Insert and Remove SIM Card from Samsung Galaxy S21 – Technipages

Although eSIM’s are rising in popularity with carriers, every smartphone still features a SIM card slot. This is so that you can swap a SIM card if something is going on with your network, or if you want to switch between phones or carriers. The Galaxy S21 is the latest flagship from Samsung, and these devices are rather impressive so you’ll want to jump on board with your existing SIM card.

In order to remove the SIM card, you will need to know the location of the SIM tray, along with a SIM ejection tool. In the event that you can’t find the tool that is included in the Galaxy S21’s box, then you can also use a small bent paper clip. Although if you are using a paper clip, you need to be a bit more careful as to not scratch the phone.

Insert and Remove the Samsung Galaxy S21 SIM Card

The SIM card tray is located on the outer frame of the front display. Look at the bottom of the phone, and the SIM card tray is located to the left of the charging port. Here’s how you can remove the SIM Card from the Samsung Galaxy S21, S21+, and S21 Ultra.

Galaxy S21 Ultra SIM Card Tray

  1. Power the Galaxy S21 off completely.
  2. Locate the eject hole on the outer frame of the device.
  3. Using the SIM eject tool (or paper clip), insert it, and gently push the button inside.
  4. The tray will eject.
  5. Carefully remove the tray from the frame.
  6. Remove the SIM card from the tray.

It’s important to note that when you remove the SIM card, a message notification pops up on your Samsung Galaxy S21 if it’s still powered on. This just lets you know that the SIM has been removed, and then goes away when the card has been re-installed.

When it’s time to put a new SIM card back into the Galaxy S21, it’s important to have the card lined up properly. If the phone is facing upwards, the gold contacts will be facing up. You can also line up the SIM Card with the outline in the tray.

Once the card is housed in the tray, line up the tray with the open hole on the outer frame. Gently push the tray back into place until it is flush with the remainder of the frame. Once the card is back, just turn it back on and you are ready to get back to business.


The Galaxy S21 lineup is already slated to be some of the best smartphones of the year, with the Galaxy S21 Ultra leading the way. These devices are available on every major US carrier, and you can even purchase one unlocked. Going the unlocked route makes it so that you are able to switch between carriers whenever you want.
