How to set up an eSIM and nano-sim card on your Galaxy device

Last Update date : 2024-06-03

SIM cards are a vital part of your Galaxy phone. Without one, you won't be able to do anything. It's important to know how to insert and activate a SIM card, or eSIM, just in case you need two phone numbers for a single device.


Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version.

What are a nano-SIM card and an eSIM?

SIM cards give you access to your wireless service provider's mobile data network, so you can make calls, send messages, and more. To have two phone numbers or service providers for a single device, you can activate an eSIM or insert two SIM cards.

Unlike a physical nano-SIM card, an eSIM is an embedded digital SIM. Please note that using both the nano-SIM card and eSIM at the same time may result in slower data transfer speeds in some areas.

Insert the dual SIM card tray properly

If you do not insert the SIM card properly, your phone may not recognize it. Check that your SIM card is placed on the tray with the gold-colored contact facing upwards and is fixed firmly into the tray.

Galaxy S22 Series phones that are designed to support dual SIM cards can be placed on both the front and back of the dual SIM card tray with the gold-colored contacts facing outwards.

  • If the SIM card is not placed exactly in the slots on the tray, returning the tray to the tray slot may not work, or the SIM card may not be recognized once inside.
  • Use only a nano-SIM card.
  • Ensure that the ejection pin is perpendicular to the hole; otherwise, the device may be damaged.
  • If the card is not fixed firmly into the tray, the SIM card may fall out of the tray.
  • If you insert the tray into your device while the tray is wet, your device may be damaged. Always make sure the tray is dry.
  • Fully insert the tray into the tray slot to prevent liquid from entering your device.

Your Galaxy phone includes an eSIM, which functions as a SIM card. You can use the mobile network after activating the eSIM or installing a nano-SIM card. To activate an eSIM, follow the steps below.
