Forgotten or Lost Code

• If you've forgotten or lost the pass code for your Boost Mobile phone, you'll know it. It's perhaps the easiest situation to remedy, though. Remove the back cover and battery of your Boost Mobile phone and write down the IMEI (International Mobile Equipment Identity number on the label in the battery compartment. Contact Boost Mobile support (see Resources), provide your IMEI number and ask for your PIN. You may be asked to sign up for a Boost Mobile account or for personal information to verify your identity, but you should be delivered your PIN over the phone or via email.
  
  

Service Provider Denial

• Your SIM card could be blocked by your service provider. If you are past due on a bill or are using a phone that's not otherwise approved for use on the network, you'll have to pay your bill or get a new code from Boost Mobile's support department before you can gain access to your phone.
  
  

Locked Phone

• Boost Mobile also could impose early termination fees and lock the SIM card if you intend to move to a new network, or if you are trying to use the phone secondhand with an old SIM card. You'll have to buy an unlock code if you don't intend to continue on with Boost Mobile. Navigate to an online unlock code site (three are given in the Resources section) and enter your phone's IMEI, model and service provider to find out if the site can unlock your phone and for how much. Prices range upward from $9.99. After you've paid and received the code via email, enter it into your Boost Mobile phone exactly as instructed by your particular vendor.
