Before you can use your phone, you need to insert your SIM.
Find the opener for the card holder. Insert the opener into the small hole in the card holder.
Remove the card holder from your phone.
Please note that your phone only supports nano SIMs.
Turn your SIM so the angled corner of the SIM matches the angled corner of the SIM holder.
Place your SIM in the holder and insert the card holder into your phone.
