VL550 SIM Card install

Use this process to disable the KPN SIM and manually configure the correct APN Settings. This ensures the terminal connects properly to the cellular network after a power cycle. 

How to Power Cycle and Disable KPN Settings 

  1. Tap the (≡) three lines on the bottom of the screen. 
  2. Go to Settings > SIM Config > SIMS. 
  3. Turn off the SIM that says KPN. 
  4. Enter the correct APN settings: 
    1. Select SIM 
    2. Select Other SIMs / Access Point Names 
    3. APN (Access Point Name): att hspa+ 
    4. Add APN: optconnect01.com.attz 
  5. Tap OK, then Save. 
  6. Tap the new APN and set it as default. 
  7. Power cycle the terminal. It should now connect to the SIM. 

If it doesn’t connect automatically: 

  • Double-check the APN name and address for accuracy. 
  • Turn Wi-Fi on and run an update, then reboot the terminal and turn Wi-Fi off again.
