How to Unlock Straight Talk Android Phones in the US

Ask for the unlock code

Call Straight Talk. Contact customer service at 1-877-430-2355 from 8:00 a.m. to 11:45 p.m., 24/7.

If you bought your phone without Straight Talk, it's likely already unlocked and no code is needed.

Tell the operator that you need an unlock code for your phone. The operator will verify whether your phone and account are eligible for unlocking.

You can go here to see Straight Talk's unlocking policy.

Only GSM phones using SIM can be unlocked. Other phone lines, such as CDMA, often cannot be used with other carriers.

Record the code. The unlock code is usually 10 to 15 characters long, which you'll need to use to unlock your phone.

Unlock your phone

Prepare SIM card. Contact the carrier of the new SIM card you want to switch to.

Power off the phone. Turn off the phone as usual.

Take out the Straight Talk SIM. Depending on your Android model, the SIM card will be in a slot on the side or under the back cover (sometimes under the battery) of the phone.

Replace SIM card. Insert the new carrier's SIM card into the tray.

Power on the phone. Instead of the usual home screen, you'll see a notification that your phone needs to be unlocked first to use the SIM card you just installed.

Enter the unlock code. Use the keypad to enter the code you receive from the Straight Talk switchboard.
Press UNLOCK . A confirmation message that the code is accepted will appear. From now on, you can use the new carrier on your Android phone.
