About giga

giga! Best Telco in an App

Launched in May 2019, giga is a digital mobile brand owned and operated by StarHub, offering SIM-only mobile plans managed entirely through a mobile app.

Reasons to choose giga

1. Unused local data rolls over to the next month
2. No-contract SIM-only plans
3. Choice of monthly or 6-month plans, depending on the plan selected
4. Fast onboarding with next working day SIM card delivery
5. eSIM support available for compatible devices

Who giga may be suitable for

giga may be suitable if you:

• Prefer SIM-only plans without long-term commitments
• Want unused data to roll over each month
• Are comfortable managing your mobile plan through an app
• Do not require bundled handset subsidies or in-store servicing
• Travel occasionally and prefer plans with bundled roaming

How giga compares to StarHub main plans

While both operate on the same StarHub network, giga focuses on simpler, no-contract SIM-only plans managed fully through an app, whereas StarHub’s main plans typically bundle longer contracts, handset subsidies, and in-store support.

This makes giga a popular option for users who prioritise flexibility and cost control over bundled devices.

Roaming and eSIM support

All giga mobile plans support eSIM, allowing users to activate their line digitally without a physical SIM card.

As of early 2026, giga includes bundled roaming data on selected plans:

• 4G plans include free monthly roaming data in five Asian countries:
  Malaysia, Indonesia, Thailand, India, and South Korea

• 5G plans include free monthly international roaming data to 48 destinations worldwide, covering parts of Asia, Europe, North America, and other regions.

Roaming allowances, supported destinations, and data quotas vary by plan tier and are subject to giga’s prevailing plan details. Users should review the specific roaming inclusions of their chosen plan before travelling. Destination lists and roaming data allowances are determined by giga and may change over time; users should verify the latest inclusions within the giga app before travel.
