Activate your phone on PagePlusCellular with the first 14 digits of its IMEI as ESN/MEID. Then you'll have MIN and MDN, let's assume 6265558888 and 6265559999, respectively. You also need to find a Verizon PRL (such as 60008.prl).
Enable DM Mode, so we can program it. If your phone is updated to 4.3, simply dial ##366633# and select Enable DM Mode:
Plug the phone to your Windows PC. If the drivers installed fine, you'll see two new serial ports in Device Manager:
Only one of the ports is what we need, let's assume COM5. If it does not work, then change to the other port (COM4) in the following steps. If you don't see these ports, you need to download and install Samsung USB drivers for your phone.
Now send SPC (000000) and Pwd (2009031920090615) to be able to access phone's secure area:
Programming, General, CONFIG: Read, Ruim Confi:, change from RuimOnly to NV_ONLY, Write. "RuimOnly" means the phone gets configuration from a UIM (SIM) card, then we cannot program it. So we change it to phone's NV area where we can access and make changes. Click "Reset", the phone will reboot.
Once the phone is boot up, send SPC and Pwd again. Need to do this every time after a reboot.
Programming, NAM. Read, fill in your MIN and MDN, then write. Optionally, you may find your SID and set it too. Under the PRL section, load the PRL, then write. Wait for few seconds for the PRL uploading to finish, then click Reset. The phone will reboot.
Now you can make phone calls and add LTE data like what's showing in this video:
Change the phone back to DM Mode disabled, as now we have done its programming. Otherwise it won't show up as a media device on your compute.
Above procedure applies to other phones, such as S3, Note 2 and etc.
