StarHub's giga! Launches Youth Plan With Unlimited AI Access for S$13.90

StarHub-owned mobile brand giga! has launched gigaFLEX+, a S$13.90 monthly plan that bundles unlimited access to ChatGPT, Claude, and Gemini alongside 800GB of regional 5G data. The offering targets Singapore's 15-to-29 age group — a segment that adopts AI at rates 35% higher than the broader customer base, according to giga!'s internal data.

The plan arrives as Singapore's mobile virtual network operators (MVNOs) compete aggressively on AI-centric features. Unlike standard data plans that treat AI tools as a premium add-on, gigaFLEX+ makes them a core part of the subscription: subscribers get a free gigaAI portal with unlimited chats across three leading models and 300 image generations per month, all within a single interface designed for studying, content creation, and side projects.

Beyond the AI bundle, the plan stacks generous connectivity allowances — 800GB of 5G data usable across Singapore, Malaysia, Indonesia, and Thailand with monthly rollover, plus 22GB of dedicated roaming data split between Asia and international destinations. A monthly PlayMade bubble tea rounds out the lifestyle pitch. The S$13.90 promotional rate is locked for 12 months for the first 9,999 sign-ups, after which it reverts to S$19.90 per month. Eligibility is verified automatically via Singpass.

Why it matters for Singapore: gigaFLEX+ is one of the first mobile plans in the market to treat AI access as a baseline feature rather than a premium upsell, reflecting how deeply generative AI has embedded into everyday life for younger Singaporeans. As telcos experiment with AI-native propositions, the plan also signals a shift in how mobile operators differentiate — moving from data volume battles to ecosystem bundling that includes AI tools, regional roaming, and lifestyle perks in a single subscription.
