How to change SIM-card for Lenovo tablet
Step 1: Make sure that you have your tablet in front of you and not in the case. You also need a small needle or something similar. You will find the SIM-card case on the button of the tablet if you have the camera lens to the right.
Step 2: Use the small needle to press into the small hole on the SIM-card case. You need to press until the case “pops up” a bit, like in the picture.
Step 3: Take out the case and change the old SIM-card with the new.
Step 4: Place the case into the tablet and press to make it get stuck back in the tablet.
