Best SIM Only plans in Singapore 2021

These days, paying $50 to over $100 per month for a 2-year contract phone plan is out of vogue, unless you really need to do that to defray your device cost. With the introduction of price-competitive SIM Only telco plans, prices for a data phone plan can be as affordable as $10 a month, while still offering large amounts of data, call time and SMSes.

Better yet, you don’t need to change your number. Porting in is easy and you wouldn’t even need to go down to a physical telco shop to do it. You can order, port your number over online and have the SIM card delivered to you.

Sounds good? Let’s see what’s being offered by Singapore telcos now.

There are literally endless options today when you’re looking at a good phone plan that can give you lots of data.

How to choose the best SIM Only plan?

When it comes to the established big three as well as their subsidiary brands (e.g. GOMO and giga), it boils down to whether you like their customer service and the speed and reliability of their networks.

Contract or no contract

You can also decide if you want to be tied down to a one-year plan or not. If you don’t mind being tied down, you can potentially get more benefits. The telcos want you to stay and will reward you for your loyalty!

For the new telcos in Singapore, there are some differentiating factors that you may find quite useful:

  • Grid Mobile: Rewards system where you can earn gridPoints and redeem stuff and get cashback

  • RedONE: Data and call time can be used in Malaysia

  • giga: Offers a phone plan under $10 for seniors and children

  • VIVIFI: You can share your data with others, which is great if you have children or elderly who don’t really use much data

  • TPG: An affordable $10 phone plan that offers 50 GB of data. But there are some reliability issues reported, especially underground.

What do you need?

Then of course, evaluate your own personal usage. More doesn’t mean better. If you just simply don’t use much data given that you’re working from home most of the time these days, then why not pay less?

Additionally, some of these SIM Only plans only offer between 100 and 200 minutes of call time. If you like chatting on the phone, or you need it for work (e.g. in a sales role), you might look to plans that offer more free minutes of call time.


And don’t forget – promotions! Occasionally, especially near those promo periods like 11.11, or 12.12, telcos will offer very attractive promotions.

For instance, for Singtel SIM Only (12 month contract), there is an ongoing promotion that offers free 30GB and 850 minutes of call time on top of the 20GB of data offered by the 20GB plan. If you’re a data junkie who is always out and about watching videos and making FaceTime calls, you will appreciate this. The extra data, talk time and SMSes expire in 12 months.

giga is also currently offering an insane plan offering 50% off your first month. If you port over your number to them, you get 50GB, 200SMSes and 200 minutes at only $9 for your first month, with no contract. It goes back to $18, which is also pretty affordable as far as SIM Only plans go.

These change from time to time, so you need to check the official websites to find the latest valid promotion.

Don’t overpay for your phone plan. It’s a recurring cost that you can definitely save a lot on in the long run!
