At giga!, we believe in keeping things simple, reliable, and– most importantly – fun! Whether you're on the move or bingeing videos, the last thing you want is a poor connection slowing you down. With giga!, you’re not just getting a plan - you’ve tapping into a delightful world of reliable network and coverage.

Which Network Does giga! use?

First things first. giga! runs on StarHub’s network, one of Singapore’s top telcos! As a fully digital telco powered by Singapore's Fastest Network, you get all the reliability and speed that StarHub brings to table, making your mobile experience seamless. Whether you’re streaming on the MRT or sending that all-important ‘on the way’ text (when you’re really not), we've got your back no matter what!

Is giga!’s 5G Coverage Good?

You betcha! We’re not just talking good—we’re talking over 99% nationwide-coverage across our sunny island kind of good. Whether you're at the top of Marina Bay Sands or chilling in Sentosa, you can roam free without worrying about losing connection—unless you’re deep underground or stuck in a lift (we can’t work miracles!). But don’t worry, in most places, our 5G will keep you flying at full speed, and even our 4G is pretty zippy too. So yeah, we’ve got you covered.

Is giga!’s Network Fast?

Let’s talk speed— and giga! doesn’t disappoint. With lightning fast 5G and 4G speeds, our network is like the Usain Bolt of mobile networks. With 5G, whether you're streaming in HD, gaming with zero lag, or just casually scrolling TikTok for an hour (or two), you’ll never have to wait for that loading bar to catch up.

But if your device isn’t compatible with 5G, don’t sweat it—our 4G speeds are no joke either. We're all about keeping things quick and smooth, so you can go about your day without digital speed bumps. TLDR? giga! is fast, and we mean really fast.
