How the PRB Calling Card Service works
  1. Select calling cards: In the configurator, choose exactly which calling cards you want us to unlock for you.
  2. Multiple selections available: You can book several calling cards at the same time.
  3. Complete checkout: secure and SSL-encrypted.
  4. Share PSN access: only inside your private Discord ticket.
  5. Manual service: a real player unlocks each calling card legitimately in-game.
  6. Optional: enable the Prestige add-on during the Very Nuclear service.
Security & process

The PRB Calling Card Service is carried out 100% manually.

  • No software, no bots, no exploits.
  • Discreet execution with no in-game messages.
  • Experienced players focused on efficiency.
  • Password can be changed anytime — recommended after completion.
Timeframe & progress

Time depends on the selected calling card and current workload. In most cases, completion takes around 1 day. You’ll receive a precise ETA after purchase inside your Discord ticket.

Your remaining in-game progress stays fully intact.
