  • Can not talk and use internet at the same time. I feel like I went 10 years back in time. Will do my month and switch back or go with GOMO.
  • Still an awesome brand coz it always remembers its own customers . Everything is in the app. Loving the Happy Hour Surprise ! Thank you giga!
  • Experience has been amazing! Everything is controlled in the App; end to end. Love their colours and characters the most. Have tried their add on packs: WhatsApp, Insta n Fb and Jetset roaming, all have been above and beyond! In their words: giga-tastic!
  • Best roaming rates. Best app experience. Love customizing my giga app. Did you know there’s even Spotify playlists curated for each giga character? And customer service is so dedicated they go above and beyond. giga is truly the best mobile service provider you can find around town 👍👍
  • To cancel your line: Press the hamburger menu (bottom left) > SIM services > Cancel Line -------- I just started using giga! will give it a few more days but I just found out that you can't share your hotspot to anyone, not even my kindle. Anyway, I would have given it 1 star for my experience with the app when signing up for my number but the customer service staff, Jun Peng, was really understanding over email. While signing up for my number the app crashed on me for about 10 times before I finally succeeded in choosing a mobile number of my choice. After going through all the nitty-gritty details and paying S$2 for the sim-card delivery. I. Was. Not. Given. The. Number. I. Chose. Heartbroken. I asked for a replacement but the delivery fee is non-refundable so I stuck to the random number that was given to me anyway. Will probably not continue after the trial. I can't even warn you to be SUPER careful when choosing your number - I literally typed out the number to choose the one and only option available and I didn't get it.

    Their on boarding process can definitely be improved. I had problem during port over and I wrote in to their giga!cares support. After I received my SIM card I can’t turn on personal hotspot too. I wrote in again and managed to solve it. For iOS: 1. Do ensure you have added giga APN - Go to Settings > Mobile Data > Mobile Data Network - Simply add the giga APN Name: giga APN: giga Everything else is left blank   2. To change hotspot APN - Go to Settings > Mobile Data > Mobile Data Network > Personal Hotspot - Change Hotspot APN to giga Hotspot APN: giga Username: left blank Password: left blank - Exit from the screen (do NOT reset settings)   3. Go to Personal Hotspot and turn it on
  • I am currently with GIGA after trying gomo, circleslife, zero1. Why i stick with giga even though i can manage with the lesser talk time and sms of gomo for a smaller bill, was that the app was easy to use. I still have Zero1, waiting for either GIGA or zero1 to improve their roaming options for me to finally stick to 1. I would not mind paying more with no data pack for other countries, but sadly they do not even have that option. Of course I can buy a data sim card at those country, but that's an extra hassle. As for CirclesLife, I did not mind paying $30/month as it had quality roaming options. Also it had a loyalty bonus, but sadly what made me left was that they discontinued it and thus i can't justify paying more (than GOMO or GIGA) for the lesser data. As for GOMO, i ended up settling with GIGA which cost $5 more per month just because of the app. I have to switch off wifi every single time, which was frustrating.
  • Giga is to be avoided if you travel. They don't have roaming. It means your phone is considered "off" once you're off the local network. For example, imagine you need to receive your bank OTP. You're screwed because there's no roaming. Imagine you are waiting for an urgent call on your SG number, tough luck. That aside, as long as you don't mind your data connection breaking/disconnecting every time you get a call, it's generally fine.
  • giga is really a great and refreshing choice for those who prefer a no frills and no contract plan. The 25GB of data is a good deal along with the 1000 minutes of outgoing calls and 1000 outgoing messages bundled with the plan. Thank you giga for making available such an awesome mobile plan, cheers 😊

About giga!

giga! offers a contract-free SIM only plan (only $25) which comes with

  • 25GB data

  • 1000 outgoing SMSes

Can I Port My Existing Number To giga!?

Yes. To port-in or transfer your existing number, ensure that:

  • It is an active postpaid number (prepaid numbers are not supported for now)
  • It is registered to your name with the same ID you're registering with giga
  • It is not with TPG (TPG does not support porting)
  • It is not on any contract with your current telco - this might incur early termination charges

Here's how the port-in or transfer process works:

  • When you choose to port-in/transfer your existing number from another telco to giga, a temporary giga number will first be assigned and delivered to you
  • Upon delivery of the temporary giga number, your request to port-in will be processed within the next working day
  • Once your port-in is approved, your temporary giga number will be automatically changed to your existing number

What Is Free Data Roll-Over?

Up to 25GB of unused data from your giga plan will be rolled over for another 2 renewal cycles. Take note that data from Jetset giga roaming pass and other packs will not be rolled over.

This way you'll never waste data!
