Perplexity Pro 1-Year Free: Which codes and partnership links are still active?

We’ve seen several Perplexity Pro promotions float around Reddit and Telegram over the past month. I audited each one this morning to see what actually activates: • **PayPal US $0 Deal**: Expired. It now shows 'Promotion has reached capacity'. • **University Ambassador Referral (Campus Program)**: **ACTIVE**. If you have a valid college email, the ambassador links grant 12 months free Pro (Claude 3.5 Sonnet, GPT-4o, DeepSeek, and image generation quotas). • **SoftBank / Deutsche Telekom Carrier Perk**: **ACTIVE**. Eligible EU & JP mobile subscribers can claim 12 months directly through their carrier perks portal. **Important**: Immediately after activating, head to Settings → Manage Subscription → Cancel Auto-Renewal. It keeps the remaining 365 days completely active, while guaranteeing you will never get charged $200 at the end of the term. Has anyone gotten the Comet browser referral bonus to stack on top?
