PUBG Mobile Version 3.9 UC Purchase Rebate Event runs December 5, 2026–January 6, 2026, offering a 7-tier reward system with cumulative bonuses from 60 UC to random 1,200-6,000 UC packs.

Servers S6, S20, S21: December 5, 2026–January 6, 2027

What's New in Version 3.9
Version 3.9 extends beyond standard 7 tiers with five additional milestones at 18,000, 24,000, 30,000, and 36,000 UC. Each unlocks random UC packs containing 1,200-6,000 UC.

UID Format: Must start with 5 and contain 10-12 digits (check Settings > Profile > Basic Info)

Two-Factor Authentication: Enable 24+ hours before first purchase (mandatory since March 2025)
Purchase Limit: $500 USD per 24-hour period
Excluded Servers: JP, KR, TW, VN (no participation regardless of other criteria)

Calculating Your Rebate: Exact Numbers
Cumulative Tracking Methodology
Only base UC counts. Purchasing 1,800 UC +300 UC pack increases cumulative total by 1,800 UC, not 2,100 UC.
Example: Three 660 UC packs (1,980 base UC) + one 1,800 UC pack (1,800 base UC) = 3,780 cumulative UC, unlocking Tiers 1-5.

Combining with Royal Pass

STARSEA AKM skin (13,000 UC) pairs well with Tier 7 completion for maximum UC availability.
Common Mistakes
Misconception #1: Only Large Purchases Count
Five 60 UC packs ($4.95 total) unlock Tier 1's +60 UC bonus. Small purchases efficiently progress early tiers.
Misconception #2: Bonus UC Counts Toward Tiers
Only base UC contributes. 5,000 UC in packs with 1,500 bonus UC = 5,000 cumulative UC, not 6,500 UC.
Misconception #3: Rewards Expire Immediately
Purchase window closes January 6, 2026, but unclaimed rewards remain available 30 days or until February 28, 18:00 UTC.
