Why Switch to a SIM-Only Plan in Singapore?

Switching to a SIM-only plan means more control over your mobile usage and no hidden charges. Unlike traditional mobile contracts, where you’re locked into long-term commitments, giga’s SIM-only plans give you the freedom to choose exactly what you need—whether that’s more data, better international roaming, or the option to switch plans for free with giga. Moreover, you do not have to pay for a device, just the plan you get!

Still deciding? Check out the benefits of using a SIM-only plan to see why so many are making the move.

If you’re on the hunt for the best SIM-only plans, it’s worth comparing what’s out there. With options tailored for data lovers, light users, and everything in between, there’s truly something for everyone.

Here are our top picks:

• $18.33 5G Plan: 400GB 5G SG & MYdata + 10GB Asia roaming + UPSIZED 6GB International roaming across 48 popular destinations + 800 mins and 800 SMS + FREE rollover data!
• $10.19 4G Plan: UPSIZED 100GB local 4G data (previously 20GB!) + 2GB Asia roaming + 300 mins & 300 SMS + FREE rollover data!

Preparing for the Switch: What You Need to Know

Before you dive in, here are a few things to prep for:

• Check your current contract. If you’re still tied to one, your provider will reject your number transfer to giga, and there might be early termination fees.
• Ensure that your current contract has an active postpaid number, registered to your Name and ID.
• Clear any outstanding bills with your ex-telco
• Know your data habits. This helps you pick the right SIM-only plan data package. Are you a heavy streamer or just a casual browser?

Pro tip: ALL giga plans are SIM-only plans with free monthly Asia roaming and rollover data that allows you to rollover your unused data to the next month! Additionally, all 5G plans also come with FREE monthly international roaming so that you can explore more places than ever!
 

How to Get Started

Making the switch is easier than you think. Here’s a simple step-by-step:

1. Choose your plan. Look for one that matches your data, call, and SMS needs.
2. Sign up online directly through our website or app in minutes, all from the comfort of your own homes. 
3. Get your SIM or eSIM: If you choose an eSIM, make sure that your device is compatible. If you choose a physical SIM, wait for it to arrive and activate your line. For eSIMs, activate it instantly and start using your service right away!
4. Port your number. Keep your existing number and transfer it easily during sign-up. Porting usually takes as fast as 1 working day, so you’ll be up and running in no time.

Whether you're looking for a SIM-only plan in Singapore with big data bundles or just something simple and fuss-free, there's a perfect fit waiting for you.
