How to remove sim card from Samsung s21


With the increasing popularity of eSIM technology, SIM cards are still an essential component in smartphones. They allow you to switch networks, change phones, or switch carriers when needed. If you’re a proud owner of the Samsung Galaxy S21, the latest flagship from Samsung, you’ll want to know how to correctly insert and remove the SIM card.

Removing the SIM card requires locating the SIM tray and using a SIM ejection tool or a suitable alternative. If you can’t find the provided tool in the Galaxy S21’s box, you can use a small bent paper clip, but be cautious not to scratch the phone.

How to insert and remove the SIM card in the Samsung Galaxy S21, S21+, and S21 Ultra

  • Locate the eject hole on the outer frame of the device.
  • Insert the SIM eject tool (or a paper clip) into the eject hole and gently push the button inside.
  • The SIM card tray will eject.
  • Carefully remove the tray from the frame.
  • Take out the SIM card from the tray.

Note that when you remove the SIM card, your Samsung Galaxy S21 may display a message notification if it’s still powered on. This notification indicates that the SIM card has been removed and disappears once the card is re-installed.

When inserting a new SIM card, ensure it is correctly aligned. If the phone is facing upward, the gold contacts on the SIM card should face up as well. You can also match the SIM card’s shape with the outline in the tray for proper alignment.

After placing the SIM card 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 rest of the frame. Once the card is securely in place, turn the phone back on, and you’re ready to go.

In conclusion, the Galaxy S21 lineup, especially the Galaxy S21 Ultra, is considered one of the year’s best smartphones. These devices are available on major carriers in the US and can also be purchased unlocked, providing the flexibility to switch between carriers whenever desired.

What to do if the SIM card doesn’t connect

If your SIM card is not connecting properly on your Samsung Galaxy S21 There are a few troubleshooting steps you can follow to resolve the issue. Here’s what you can do:

  • Restart your phone: A simple restart can sometimes fix minor connectivity issues. Turn off your Samsung Galaxy S21, wait for a few seconds, and then turn it back on.
  • Check SIM card compatibility: Ensure that your SIM card is compatible with the Samsung Galaxy S21. Double-check if the SIM card is your device’s correct size and format. The Galaxy S21 uses a nano-SIM card.
  • Clean the SIM card: Dust or debris on the SIM card or SIM card tray can interfere with the connection. Gently remove the SIM card from the tray and clean it with a soft, lint-free cloth. Also, inspect the tray for any debris and clean it if necessary.
  • Reinsert the SIM card: Remove the SIM card from the tray and carefully reinsert it, ensuring it is properly aligned with the tray and the gold contacts are facing down. Push the tray back into the phone until it is flush with the frame.
  • Check for network settings: Go to the Settings menu on your Galaxy S21 and navigate to “Connections” or “Network & Internet.” Check if the network mode is set to the appropriate option (e.g., 4G LTE) and that the network operator is selected correctly.
  • Update your device: Keeping your Samsung Galaxy S21 up to date with the latest software can often fix bugs and improve connectivity. Check for any available software updates in the Settings menu under “Software Update.”
  • Test with a different SIM card: If possible, try inserting a different SIM card into your Galaxy S21 to determine if the issue lies with the SIM card itself or the phone. If the new SIM card works fine, then the problem may be with your original SIM card.
  • Contact your carrier: If none of the above steps resolve the issue, reach out to your mobile carrier’s customer support. They can provide further assistance, check your account status, or determine if there is a network-related problem in your area.

Remember to follow any instructions provided by your carrier or the Samsung support team if they suggest additional troubleshooting steps specific to your situation.

By following these troubleshooting steps, you should be able to resolve most SIM card connectivity issues on your Samsung Galaxy S21.
