How to Break a SIM Card Code From Boost Mobile Into an AT&T Phone
- 1). Log on to your Internet browser and go to a site that offers unlock codes for cell phones (see Resources). Some cell carriers will give out unlock codes if you request one from a customer service representative, but this rarely happens. If this is your case, you will need an online resource to generate an unlock code, and this will cost.
- 2). Enter the make and model of your AT&T phone in the required fields on-screen.
- 3). Enter your payment and email information and confirm the purchase. The site will then generate the code and send it to your email account.
- 4). Open your email account and retrieve the unlock code.
- 5). Enter the code in your AT&T phone and press "Send." The phone will then unlock and be compatible with any SIM card.
- 6). Locate the SIM compartment on your AT&T phone. On most phones the SIM card is located behind the battery in the battery compartment.
- 7). Remove the current SIM and replace it with your Boost Mobile SIM. You will now have Boost Mobile service on your AT&T phone.
