To install a SIM card into your Galaxy S20 Ultra you need to:
- Find the SIM Card slot at the top left of your device
- Locate the small pin hole on the SIM slot
- Use your SIM Tool (included in your Galaxy S20 Ultra box) and insert the pin into the hole. This will eject the SIM tray.
- Use your fingers to pull the tray all the way out
- Place your SIM card face down into the tray with the gold contacts facing down
- Place the SIM tray back into the slot and push all the way in
- You can often use the SIM card from your old device
- It must be a nano-SIM
- 5G connectivity will depend on your carrier
