If you’re between the ages of 15 and 29, you can now access a sweet new deal from giga. The new plan, called gigaFLEX+, costs $13.90 per month for the first twelve months, then $19.90 for every month after that.

It includes a subscription to gigaAI, which means unlimited access to artificial intelligence models like Claude, ChatGPT, and Gemini, as well as 300 free image generations per month.

In terms of data, you’ll get a massive 800GB of 5G data that can be used in Singapore, Malaysia, Indonesia, and Thailand. This data also rolls over monthly, so if you don’t get through it all, it’s stacked onto your allowance for the following month. It also comes with a generous 22GB of monthly roaming data, which includes 12GB of Asia Roaming and 10GB of International Roaming to over 48 destinations. You’ll also get 1,000 SMSes and 1,000 local minutes.

Plus, as the cherry on top, you’ll get one free PlayMade bubble tea every month.

This offer is only available to the first 9,999 customers who sign up for the gigaFLEX+ plan. To redeem the offer, head to giga!’s official website or download the giga! app to sign up.
