    giga! SIM Only 5 GB Plan

    I signed up a port-in 5GB plan on 30 Nov 2019 via a computer fair for a promotional first-month subscription fee of $1. SIM card delivery fee of $2 was waived because I collected the new SIM card on the spot. [Ease of porting] When I insert the new SIM card, it was under a temporary number. I got to do a one-time APN setup and the instructions are available clearly on the mobile app. On the next day (1 Dec 2019), it was successfully updated to the ported-in number. [Billing] Billing was easy to setup via the "Payment method" option in the mobile app. Automated bill payment via GrabPay Mastercard works well without issues.

    giga! SIM Only 5 GB Plan

    [Network] Haven't got to try giga! services yet but will soon port into it after hearing the raving reviews. [Mobile App]Value for money plan as it cater to low-end data users like me for a cheap price point.

    giga! SIM Only 25 GB Plan

    The worse Telco in terms of network and customer service. Bought additional plans for data roaming and idd calls. The most irritating experience, no network from 26 Dec till the last date 29 December I left Philippines. The worst was, not being able to contact home to find out about my mum who was unwell. Very stressful, wrote in to express my dissappointment and received a standard answer, sorry to hear about your grievances. Out idd calls are for calling overseas only. No mention of any form of compensation even for data roaming, and the loss of network even after I came to Singapore. Called the technical side. They were very helpful in trying everything without giving up. I managed to connect after switching on and off a few times. Even now, after 1 month, I couldn't call home or use wats app when I was outside home. Gets disconnected at least twice a day. Wrote in on Jan 16, still no response.

According to their terms, you cannot use voice (including but not limited to outgoing and incoming voice calls and SMS) overseas. However, you will be able to receive SMS and this service is free. To do this, it will be under gigaRoam pass Asia Pacific. Here is everything about me and what I do best.

You may stack the data pack with 1GB data for $2. The validity will follow your plan's month cycle and renews accordingly. Here is everything about me and what I do best.

About giga!

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

  • 25GB data
  • 1000 outgoing minutes talk time
  • 1000 outgoing SMSes
  • Free Caller ID
  • Free data rollover
  • Free incoming talk time and 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!
