13 Cheapest SIM-Only Mobile Plans in Singapore 2021 (<$20/Month)

Sim-Only-Plans_1_masthead

Gone are the days when you’d have to sign up with one of the big 3 telcos — Singtel, Starhub and M1 — just for mobile data.

With one of these cheap SIM-only data plans, you’d no longer have to commit for 2 years and be obligated to wait for re-contract discounts on your new handset. Just take the money you save on your SIM-only plan, and get yourself a new phone on Lazada.

With so many new players and virtual telcos like Circles.Life, TPG, redONE and so on joining the fray, mobile data plans are now a buyer’s market. Check out how the cheapest SIM-only mobile plans stack up.

13 cheapest SIM only plans under $20/month

SIM only plan Monthly subscription Data / outgoing talktime / SMS
Circles Life $5 Plan $5 2GB / 50 min / 25 SMSes
redONE Amazing 8 $8 3GB / 300 min / 10 SMSes
VIVIFI Lite $8.80 3GB / 500 min / 20 SMSes
Zero 1 6u Plan $9.90 for first 6 months, $13.90 thereafter 6GB / 200 min / 200 SMSes
TPG $10 50GB / 300 min / 30 SMSes
giga (Starhub) $10 6GB / 100 min / 100 SMSes
MyRepublic Lite $10 6GB / 300 min / 300 SMSes
China Mobile $10 5GB / 100 min / 100 SMSes
MyRepublic $17 (promo price; U.P. $20) 50GB / 500 min / 500 SMSes
Grid Mobile $17.90 20GB / 120 min / 50 SMSes
Circles Life Smart Start $18 (port over) 20GB / 100 min / 25 SMSes
GOMO (Singtel) $20 20GB / 200 min / 200 SMSes
M1 $20 (Safra promo; valid 12 months) 40GB / 1,000 min / 1,000 SMSes

Circles Life SIM-only plans (from $5/month)

Circles Life has the absolute cheapest SIM-only plan on the market at just $5/month! Here are the plans you can choose from:

  • Circles Life $5 Plan comes with 2GB data, 50 minutes of talktime and 25 SMSes
  • Smart Start Plan ($18/month if you port in, otherwise $28) with 20GB of data, 100 minutes talktime, and 25 SMSes

It’s pretty easy to manage your Circles Life SIM-only plan; if you run out of data or talktime, you can just purchase a “Boost” on the app.

The biggest downside is a very high one-time SIM card registration fee of $38. If you get a Smart Start plan, you can usually get this fee waived with a promo code.

redONE SIM-only plans (from $8/month)

redONE is a Malaysian telco with some attractive SIM-only plans. Choose from 3 redONE plans:

  • redONE Amazing8 plan ($8/month) gives you 3GB of data, 300 minutes of talktime and 10 SMSes.
  • redONE Amazing18 plan ($18/month) offers 10GB, 500 minutes of talktime and 20 SMSes.
  • redONE Amazing28 plan ($28/month) has 20GB, 700 minutes of talktime and 30 SMSes.

Its main selling point is that the bundled mobile data can be used in Singapore and Malaysia — clearly the plans are aimed at Malaysians living here.

VIVIFI SIM-only plans (from $8.80/month)

VIVIFI is yet another virtual telco with 4 SIM-only plans to choose from:

  • VIVIFI Lite ($8.80/month) with 3GB, 500 minutes of talktime and 20 SMSes
  • VIVIFI Plus ($9.98/month) with 6GB, 350 minutes of talktime and 100 SMSes
  • VIVIFI Plus ($14.98/month) with 10GB, 350 minutes of talktime and 100 SMSes
  • VIVIFI Share ($29.90/month) with 40GB, 300 minutes of talktime and 100 SMSes

While the first 3 SIM-only plans are pretty self-explanatory, we actually like the more expensive VIVIFI Share Plan the most.

You can share this plan with up to 8 other users; each user has to pay $5.35/month and will get an additional 2GB each. This arrangement may be suitable for couples with young children or elderly.

So for example, you, your husband and your child share a VIVIFI plan. You pay the base price of $29.90 and an additional $10.70 to add on 2 users. The total price comes up to $40.60, or $13.53 per person, and 3 of you get to share a total of 44 GB.

Zero 1 SIM-only plans (from $9.90/month)

Zero 1’s gimmick is that all their plans have “unlimited” data. Apparently, you get 4G speeds on the first GBs that you pay for. Thereafter, your data will be at “managed” speed (read: slow but supposedly “usable”). But at least you’re not forced to top up for extra data.

  • 6u Plan ($9.90/month for 6 months, $13.90 thereafter) offers 6GB data, 200 minutes of talktime, and 200 SMSes
  • 30u Plan ($24.90/month) has 30GB data, 450 minutes of talktime and 450 SMSes.

For the 6u plan, you need to pay a one-time registration fee of $10.70. For the 30u, this fee is waived for new subscribers for a limited time only.

TPG Singapore SIM-only plans (from $10/month)

TPG, the Australian telco that snagged the fourth telco licence in Singapore in 2016, has 2 “spoil market” SIM-only plans:

  • 50GB ($10/month) with 300 local call minutes, 30 local SMSes, plus 1GB of roaming data to selected countries.
  • 80GB ($18/month) with 500 local call minutes, 300 IDD minutes, 50 local SMSes, and 2GB roaming data to selected countries

Sounds like an amazing deal, but the downside is that TPG does not work with all devices. Check here for a list of compatible handsets.

Note: If you/your parents are 60 years old and above, consider TPG’s Seniors Go Digital Plan at $5/month s till 31 July 2021.

Starhub giga SIM-only plans (from $10/month)

giga is Starhub’s entrant on the virtual telco scene, and it has 2 plans to choose from:

  • $10/month for 6GB of data, 100 minutes of talktime and 100 SMSes.
  • $25/month for 45GB of data, an insane 1,000 minutes of talktime and 1,000 SMSes.

The $25/month giga plan is on the expensive side — although that’s a crapload of data and talktime. So if you’re a modest phone user, the $10/month plan should be enough. giga plans all roll over unused data to the next month, which means you can theoretically get more data than you paid for.

MyRepublic SIM-only plans (from $10/month)

MyRepublic has refreshed its offerings to be more competitive than before, especially with its current (indefinite?) flash sale. Here are the plans:

  • Lite ($10/month) for 6GB of data, 300 minutes of talktime and 300 SMSes.
  • Core (currently $17/month; usually $20) for 50GB of data, 500 minutes of talktime and 500 SMSes.
  • Value ($18/month) for 14GB of data, 1,000 minutes of talktime and 1,000 SMSes.
  • Pro (currently $24/month; usually $29) for 70GB of data, 1,000 minutes of talktime and 1,000 SMSes.
  • Unlimited ($39/month) for unlimited data, 1,000 minutes of talktime and 1,000 SMSes.

Although the Lite plan is the cheapest, we prefer the similarly-priced giga for its rollover data feature. The Core plan is the best of the lot at just $17 if 50GB — perfect if your phone isn’t compatible with TPG.

China Mobile SIM-only plans (from $10/month)

Newcomer China Mobile has these SIM-only plans to offer:

  • 5GB ($10/month) with 100 minutes of talktime and 100 SMSes
  • 20GB ($20/month) with 300 minutes of talktime and 300 SMSes
  • 100GB ($40/month) with 300 minutes of talktime and 300 SMSes

As you can guess from its name, China Mobile is very much aimed at mainland Chinese living in Singapore.

All of its data can be shared across Singapore, mainland China and Hong Kong, while its talktime can be used either locally or to selected countries (China, Hong Kong, Malaysia, Indonesia, Thailand and USA).

GridMobile SIM-only plans (from $17.90/month)

GridMobile now offers 2 SIM-only plans:

  • GridMobile 20GB plan ($17.90/month) with 120 minutes of outgoing calls and 50 SMSes.
  • GridMobile 40GB plan ($24.90/month) with 200 minutes of outgoing calls and 200 SMSes. Also comes with 1GB TravelRoam in Malaysia for new sign-ups, but that will only be worth considering when we get to travel again.

GridMobile’s $17.90/month plan is the cheapest 20GB plan on the market. A good option if your data usage exceeds 10GB (and your phone isn’t compatible with TPG).

You can also boost your plan with one-time or monthly add-ons for data/talktime, and earn gridPoints to offset your bills, get cash back, or spend at merchants like Grab and Shopee.

Singtel GOMO SIM-only plan ($20/month)

Stressed out by the likes of Circles Life, Singtel’s sub-brand GOMO is meant to win back the hearts and minds of disloyal Singaporean millennials. It now has 2 main plans:

  • 20GB ($20/month) with 200 minutes of talktime and 200 SMSes
  • 50GB ($30/month) with 500 minutes of talktime and 500 SMSes

Although its $20 for 20GB plan used to be the market leader, it’s now facing stiff competition from TPG, MyRepublic and Grid Mobile. That said, it’s still a good price for the security of a Singtel product. You can manage your plan easily with the GOMO app.

M1 SIM-only plan (from $20/month)

Shortly after Singtel’s GOMO and Starhub’s giga, M1 joined in the fray too. But instead of trying to ingratiate itself with millennials, M1 has simply updated their one SIM-only offering. This SIM-only plan is fully customisable to your needs, starting from $15.95/month for 5GB data. 

If you’re a new customer and a Safra member, there’s are a couple of pretty good deals:

  • $20/month for 40GB of data, 1,000 minutes talktime, 1,000 SMSes, with unlimited free calls to 3 M1 numbers
  • $30/month for 90GB of data, 1,100 minutes talktime, 1,000 SMSes, with unlimited free calls to 3 M1 numbers

So, which is the best SIM-only plan in Singapore?

How do you know which plan to sign up for? Here’s a quick guide:

 


If you want a cheap and basic SIM-only plan: giga or MyRepublic ($10/month)

SIM only plan Monthly subscription Data / outgoing talktime / SMS
Starhub giga $10 6GB / 100 min / 100 SMSes
MyRepublic Lite $10 6GB / 300 min / 300 SMSes

Our recommendation for lite phone users is either giga or MyRepublic, whose $10/month plans are comparable — both  give you a decent 6GB to play with.

If you don’t want to sacrifice your data: TPG ($10/month) or MyRepublic ($17/month)

SIM only plan Monthly subscription Data / outgoing talktime / SMS
TPG $10 50GB / 300 min / 30 SMSes
MyRepublic $17 (promo price; U.P. $20) 50GB / 500 min / 500 SMSes
GOMO (Singtel) $20 20GB / 200 min / 200 SMSes
M1 $20 (Safra promo; valid 12 months) 40GB / 1,000 min / 1,000 SMSes

If your phone is compatible with TPG, you really can’t beat TPG’s $10 plan. Like we said, they spoil market one.

Otherwise, we like MyRepublic ($17/month), GOMO ($20/month) and M1 ($20/month). All 3 plans come with a decent amount of talktime and SMSes, so they won’t make you feel like you’re sacrificing any part of your life just to save a few bucks.

(At the $18 mark, Grid Mobile and Circles Life may be a litle cheaper, but both plans run low on the talktime and SMSes.)
