How to Find the Number of a New SIM

By Janos Gal

All SIM (Subscriber Identity Module) cards have a specific I.D. number so the manufacturer or subscriber can easily identify the SIM. If there is no SIM card in your phone, you can only make "911" emergency calls. Additionally, if you subscribe to a contract with a wireless provider, you can easily transfer your account information like contact numbers or text messages from one handset to another by transplanting the SIM card. However, to do that, you may need the SIM card's I.D. number, which you can find by removing the SIM card from the phone.

Things You'll Need

  • Magnifying glass

Step 1

Remove the back cover of the cell phone. Every cell phone has a different back cover, so check the manufacturer's instructions on how to remove it.

Step 2

Remove the battery. All SIM cards are behind the battery, so you must remove the battery to reach the SIM card. Follow the manufacturer's instructions if you are unsure how to remove the battery.

Step 3

Click open the SIM card holder and carefully remove the SIM card. Avoid touching the golden colored metal side of the SIM card.

Step 4

Place the SIM card on a flat surface and take a note of the SIM card number located under the gold-colored metal chip. You may need to use a magnifying glass if you cannot read small numbers.

Tips & Warnings

  • The SIM number is located in the same place, regardless of the age of the SIM card.
