Hi there Brianmagoon. All network settings should happen automatically when the device is programed the first time. Please follow the steps below:
1. Go to Settings
2. Turn of Wi-Fi
3. Mobile Data on
4. On your dial pad press ##72786#
5. Press yes or ok to whatever you see there. Your device may turn off and on at least twice. The whole process should not take more than 6 minutes give or take. Let me know how that worked out.
It's kind of a crap shoot but MSL 000000 will sometimes work. Otherwise you will just have to find a knowledgeable boost rep who can supply you with the correct msl for your device.
For the benefit of others,
An MSL is a 6-digit code unique to your CDMA device that's necessary to access some of your handset's deeper functions, such as wiping a phone number or manually programming in a new one. GSM devices do not have MSL code.
