One of the simplest ways to fix SIM-related issues is by temporarily disconnecting the SIM card. This usually works because sometimes, network issues may occur if a SIM card is loosely connected or when there’s an issue with the SIM card itself. If you haven’t tried this yet, be sure to remove the SIM card and see what happens after re-inserting it.

Below are the steps to remove a SIM card:

  1. Turn off your Galaxy Note10+. This is important. Inserting a SIM while the device is on may result to corrupted data.
  2. With your phone’s screen facing you, remove the card tray. You can use the insertion/removal tool (or a paperclip) to unlock the tray by inserting it into the provided slot. This small hole should be visible on the top part of your device.  
  3. Remove the SIM card from the tray. You can lift the card up from the bottom. To assist, use the opening on the opposite side of the tray to dislodge (using a fingernail or similar tool).

After a few moments, re-insert the SIM card. Be sure that the phone is OFF when doing this.

If nothing changes after reseating the SIM, your next move is to see if the issue is caused by a defective SIM card. There are two ways to do this. One is by getting a new SIM card from your carrier. The other way is to borrow a known working SIM card from someone (be sure it’s compatlible with your carrier) and see if your Note10+ detects the card. Either of these methods should help you determine if the No SIM card detected error on your Galaxy Note10+ should help in knowing if you have a SIM card problem. If you think that the current SIM card is defective, get a new one from your carrier right away. Although SIM cards are extremely durable, they can still go bad. Getting a new one is the easiest way to resolve a SIM card problem.
