How to Change a SIM Card

by Ty Arthur

Phones that are provided by a GSM cellular network such as AT&T or Cellular One use small identification chips that house your subscription plan information called Subscriber Identity Module (SIM) cards. If your SIM card goes bad or is lost, you may have to manually change out the card with a new one on your own. Replacing the card only takes a few moments and can be done without any special tools.

1

Contact your cellular service provider and have it provide you with a new SIM card. Let it know your account and phone number so that it can transfer your phone service to the new SIM card.

2

Check the manual that came with your phone to see if the SIM card is found in the standard location beneath the battery or if it's located somewhere else.

3

Turn your phone over and remove the back plate by pushing down on the slide panel and sliding it away from you. Remove the plate and then put your finger in between the battery and the side wall. Push the battery away and pull it out of the phone.

4

See if the SIM card has a metal covering. Remove the covering if there is one present and then pull the SIM card out.

5

Place the new SIM card in the card holder and then snap back down the metal covering. Make sure to place the card in the same direction as the old card or your phone will not be able to read it. Put the battery back in and then place the back panel back on. Power on your phone to ensure that the SIM is working properly.

Tip

  • check SIM cards come in different carrying capacities that may not work with all phones. Be sure to check with your provider to find out what size card your phone uses if you plan to purchase a SIM card from a source other than your cellular carrier.

Warning

  • close Do not enter in any codes if the phone asks for a "PUK" or "SIM lock" code. Contact your cellular provider immediately and request the code because if you enter in an incorrect code, your SIM card will permanently deactivate itself.
