How can I check if my phone prompts for the unlock code?

If your phone is any make other than LG, you can check if it prompts for the unlock code by inserting a SIM card from a network other than the original.

Once you've done that, a message will appear on screen prompting for the unlock code or SIM network unlock PIN. If you get another message, contact us immediately for assistance.

If you have an iPhone, you will be told the SIM card inserted does not appear to be supported.
