The OfferOps Perk-Stacker’s Complete GrabUnlimited → ChatGPT Plus System
The OfferOps Perk-Stacker’s Complete GrabUnlimited → ChatGPT Plus SystemSimple-Pimple: Malaysia’s GrabUnlimited still gives legitimate 1-month ChatGPT Plus codes through GrabRewards. Most people grab one and call it a day. Perk-stackers build systems.
Current Status Check
Valid: Confirmed active as of September 2025. GrabUnlimited subscribers in Malaysia get ChatGPT Plus codes via GrabRewards (Lowyat coverage, PriceShop details).
Limitations: One-time redemption per GrabUnlimited subscriber. Expires Dec 31, 2025 (or earlier—check in-app).
What Changed: The original “VPN + unlimited accounts” advice was wrong. Here’s what actually works.
Phase 1: Infrastructure Setup
Phone Numbers That Actually Work
Testing Phase (Free but unreliable):
- Receive-SMS.com - Malaysia +60 numbers, shared/public
- Good for: Proving the concept works
Scaling Phase (Reliable):
- OnlineSim.io - $0.10-0.50 per dedicated Malaysia number
- SMS24.me - $0.20-1.00 per number, higher success rates
- Premium services - $2-5 for private numbers with guaranteed delivery
Pro tip: Batch purchase 10-20 numbers at once. Individual purchases scream “amateur hour.”
Virtual Cards That Don’t Suck
Global Winner: Wise Virtual Card
- No monthly fees, works everywhere ChatGPT accepts payment
- Instant issuance, multi-currency support
- Load $2-5 minimum for ChatGPT activation
Regional Backup: BigPay (Malaysia)
- Free virtual cards, good for maintaining local payment patterns
- Wise for scaling, BigPay for authenticity
Advanced Option: Alliance Bank VCC (Malaysia)
- 16-digit number rotates every 30 minutes
- Zero fees, actual credit building potential
Phase 2: Account Generation Flow
Step 1: Geographic Setup
Target cities: Kuala Lumpur, Penang, Johor Bahru
Use real addresses from Google Maps
Maintain consistent location per account
Step 2: Grab Account Creation
- Download Grab app, set region to Malaysia
- Use dedicated phone number from your OTP service
- Complete signup with realistic Malaysian address
- Add your virtual card (minimum $2-5 balance)
Reality check: Don’t use your real location if you’re not in Malaysia. Geographic consistency matters.
Step 3: GrabUnlimited Subscription
Pricing (official rates):
- RM4.90/month ($1.10 USD)
- RM27 for 6 months
- RM47.90 for 12 months
- New users: “Try 2 months for free” promotion available
Subscribe to monthly plan. Cancel before renewal if you’re not continuing.
Step 4: Code Extraction
- Open Grab app → Account → GrabRewards
- Find “ChatGPT Plus – 1 Month” tile
- Ignore any “Sold Out” status—claim anyway (source)
- Extract the unique activation code
- Store in your tracking system (more on this below)
Phase 3: Automation & Scaling
Essential Tools Stack
Browser Automation:
- Selenium/Playwright for account flows
- ProxyMesh for Malaysian IP rotation ($10-30/month)
- 2Captcha for automated solving ($2-5/month)
Management System:
- Airtable/Notion for code inventory
- Telegram API for customer communication
- Payment tracking spreadsheet
Batch Processing Workflow
1. Bulk purchase phone numbers (10-20 at once)
2. Parallel account creation (3-5 simultaneously max)
3. Stagger subscriptions across 24-48 hours
4. Extract codes within 72 hours of subscription
5. Store codes with expiry tracking
Don’t rush the timing. Grab’s systems notice suspicious patterns.
Phase 4: Monetization Strategy
Resale Channels That Work
Telegram Groups: ChatGPT-focused communities
- Commission: 0-10%
- Volume: Medium to high
- Best for: Direct sales, building reputation
Digital Marketplaces: Shows $3-18 range
- Commission: Platform dependent
- Volume: Consistent
- Best for: Passive income stream
Gift Card Platforms: Zingoy model (5-15% commission)
- Volume: High in supported regions
- Best for: Established inventory liquidation
Bundle Strategy (The Real Money)
Instead of single ChatGPT codes:
Premium Digital Bundle: ChatGPT Plus + Spotify + Canva Pro
Student Power Pack: ChatGPT + Office 365 + Adobe Creative
Streaming Combo: ChatGPT + Netflix + Disney+ (regional codes)
Markup: 30-50% premium for convenience packaging
Customer psychology: People pay more for “complete solutions”
Phase 5: Risk Management
Technical Safeguards
- Device fingerprinting: Each account gets unique browser profile
- Payment isolation: Cycle virtual cards to avoid pattern detection
- Geographic consistency: Always use Malaysian IPs during critical operations
Legal Framework
- GrabRewards TOS allows one redemption per subscriber (help docs)
- ChatGPT Plus permits code transfers within reasonable use
- Follow local consumer protection laws for your sales jurisdiction
Exit Strategy Planning
When this promotion ends (likely Dec 31, 2025):
- Monitor similar programs: Singapore, Thailand, Philippines (Grab regional)
- Pivot system to other subscription perks (Spotify, Netflix, Adobe)
- Scale methodology to carrier promotions (Samsung, T-Mobile, etc.)

- Customer service (when codes don’t work)
Legal considerations:
- Check local laws on digital goods resale

- Provide actual value through bundling/convenience
- Honor refund policies and customer support
Next-Level Moves
Platform Diversification
Apply this methodology to:

System Evolution
As you scale:
- APIs over browsers - More reliable, faster execution
- Merchant partnerships - Direct relationships with service providers
- White-label solutions - Sell the system, not just the codes
- Geographic expansion - Multiple countries, multiple programs
Final Word: Most people see “free ChatGPT Plus” and think small. Perk-stackers see infrastructure, automation, and recurring revenue streams. The codes are just the beginning.
What separates professionals from amateurs? Professionals build systems that outlast individual promotions.
