How to Insert SIM Card For Smartwatch

Before you insert the SIM card into the smartwatch, you need to know where the SIM card slot is located on your device. Generally, it may either be on the side panel of the watch or on the backside of the watch.

Case 1: If it is on the side panel of the watch

This configuration is easier for the user to insert/remove the SIM card because it does not mandate the removal of the back panel or any kind of fasteners such as screws.

  • Open the rubber/ plastic/ metal lid on the side panel of the watch by pushing/ pulling it.
  • You might see a SIM card tray or a SIM card slot. In case there is a tray, you’ll need to push/ pull it to take it out. Then place the SIM card on the tray carefully. You need to ensure that the golden chip of the SIM card is facing up and then, put it back. If you see a slot, you may refer to the manual to know whether the SIM should be facing up or down. Once you figure that out, you may close the lid and switch on the device.
  • Usually, the smartwatch will display network connectivity if the SIM card is properly placed. In case it doesn’t show the connection, you may contact your service provider.

Case 2: If the SIM card slot is on the back panel

Opening the back panel might be tricky at first, but it gets easier gradually. Depending on the type of watch you have, you might need a thin plastic object and a screwdriver to open the back panel. This takes up a relative amount of force, so you must be careful while you open it.

  • Remove all the screws present on the back panel, if any.
  • Use the flat, plastic object to remove the back panel.
  • Insert the SIM card in the slot provided. Make sure that the golden chip is facing downwards.
  • Close the back panel, insert the screws, and switch on your watch.
