To retrieve your SIM card number (ICCID) number, begin from the home screen:
1. Press the “Menu” button and select “Settings.”
2. Scroll down and click on “About.”
3. Click “Phone Identity” or “About,” depending on the model you are using.
4. Your SIM number should appear as the SIM ID (or ICCID in some cases).
If your phone will not power on, you can simply get the SIM card number by ejecting it from the SIM slot or by pulling it out from a tray on the phone. Androids can have different locations for the SIM card. Occasionally, a SIM tool or push pin may be required to open a SIM tray. If your phone has this design, simply put the tool or the push pin into the small hole located next to the tray and it should eject the SIM card.
