Both of these methods is easy to do, no need to pay and no root required.


Method 1: Ask your carrier to unlock the phone
The first method that you can do to unlock your phone is by asking the unlock code from your provider. Here are the complete steps to do:
  1. Reach the provider through the calls or emails to ask them to unlock your phone. You can give them the explanation of what the reason that force you to unlock the phone, for instance you need to unlock the phone because you want to go to abroad, etc. FYI, some of carriers may refuse to unlock the phone until the contract is over, or you have to use their services for certain time period. If you managed to get the code then go to the next step, while if your carrier doesn't provide you the code then try to use the next methods.
  2. Turn the phone off, remove your old SIM card and insert with the new one.
  3. Turn on the phone.
  4. You'll see an 'Enter the unlock code' screen. Enter the unlock code here. Once you've finished, now you can use the phone with the service from the new provider.

Method 2: Unlock the phone from the Service Menu
If your carrier refuse to provide you the code, then you still be able to unlock the phone by following the easy steps as listed below:
  1. To make it works, make sure your Samsung Galaxy SIII is already with the Android 4.1 or above. You can check the software version through About device under the Settings menu.

    1. Hi Heather Card,
      Thanks for coming.
      Theoretically, you should see the unlock code screen whenever you put another SIM card in a locked phone. However, CMIIW, Virgin mobile is a CDMA network, isn't? So, make sure the second card is a CDMA card.
      Other way, you can also call your provider to unlock your phone if you have a good reason to do so or if your contract is over.

    1. Hi Shaz,
      Thanks for coming.
      While you're in the service mode screen, use the Menu key>"Select"> input the row number.
      Anyway, if you already have the unlock code, try to insert your new SIM card. If you're presented with the "enter the unlock code" screen then you can enter your unlock code here. If not, you can open the Phone app and then dial #0111*(your_unlock_code)#
