Every spending situation is unique. SingSaver assembles the ‘Best For‘ list, so you can decide what’s best for you.

Break free from lock-in contracts with the best SIM-only plans in the market.

The SIM-only, mobile plan war is now in full swing.

Gone are the days when fixed mobile plan contracts by Singtel, StarHub, and M1 locked you in for a period of 12- to 24-months with no way out except by paying a hefty early termination penalty. 

How did they attract you to sign up with them? The main tactic was to dangle the latest smartphone at an attractive upfront ‘discount’ — provided you re-contract with them, locking you in again for another 12 to 24 months.

Obviously, it wasn’t really a discount; the cost of the smartphone was really just spread out over monthly instalments.  

Here’s what we’ll cover in this article:

Last updated on 1 June 2022. SIM-only mobile plans and promotions are subject to change without prior notice.

Entry of new players flood the market

The two latest mobile virtual network operators (MNVOs) to join the battle are redONE (through StarHub’s mobile network), ViViFi (SingTel’s mobile network).

Add these two to the ranks of My Republic, Circles.Life, Zero1 and TPG, and suddenly, a myriad of flexible smartphone plans at attractive rates are now available, with no lock-in contracts. These are commonly referred to as SIM-only contracts.

This means consumers are now spoilt for choice when it comes to choosing the most affordable and cost-efficient mobile plans for their needs.

This has forced the traditional incumbents — StarHub, M1 and Singtel — to also up their game, and in the first half of 2019, all three have launched their own version of SIM-only plans to try and regain market share. 

The other major game disruption in the mobile telco wars is the emphasis now on data — SMS is a thing of the past, so are calls made over landlines.

All you need is a stable wifi or data connection and you can talk long-distance, message and even do video calls, for free, through chat apps like WhatsApp, Facebook Messenger, Skype, WeChat… and the list goes on.

Add to this the ubiquity of streaming services like Spotify, Netflix and YouTube, as well as online gaming, and you’ll understand why data is now so critical to your mobile plan.

So which SIM-only, no contract mobile plans are best in the market right now? It depends on how much data juice you need.  Decide if you are a light, moderate, or heavy data user and check our comparison price plans below.

*Check this page regularly as telcos are quick to change their price plans to match the competition.

What is a SIM-only plan?

A SIM only plan offers a package of data, talk time, and SMSes at a fixed monthly cost.

SIM-only plans are postpaid plans, and function much like traditional mobile phone contracts. The main (and most important) difference, however, is that you are not locked into a minimum contract period, and you are free to switch telcos or mobile plans as and when you wish with no penalty.

Which is the best SIM-only plan?

The best SIM-only plan really depends on how much data you need. Check your previous telco bills or the data tracking app on your handset to see how much data you use on average each month. Also keep in mind how much talk time and SMS you use monthly before picking the most suitable SIM only plan for your needs.

Which is the cheapest mobile plan?

It’s hard to beat Circles.Life’s S$5/month Plan if you’re looking at the absolute cheapest.

  • 2GB data
  • 50 minutes of talktime (incoming and outgoing)
  • 25 SMS
  • Free caller ID

The catch is that if you exceed 2GB data a month, you’ll need to top up your data plan, starting at S$8 for an additional 1GB of data or S$12 for 2GB of data.

Similarly, for calls or texts, you’ll need to top up S$5 for 30 minutes talktime + 10 free SMS or $10 for 200 minutes talktime and free incoming calls.

Is a SIM-only plan better than a fixed contract?

Not necessarily. The main advantage of a SIM-only plan is that you are not locked into any telco for a minimum contract period. However, SIM-only plans come with, well, the SIM card only. So if you need a new handset, telcos like StarHub offer attractive discounts for 12- and 24-month contract plans. Research handset prices before you commit to either SIM only or contract plans.

How much data do you need?

According to a 2018 study by Info-comm Media Development Authority (IMDA), Singapore residents consumed about 70 petabytes of mobile data per month in Q4Y2021— up nearly 27 per cent from about 55 petabytes monthly in Q4Y2020. Of course, if you spend a lot of time on your phone to play mobile games, stream a lot of music on Spotify or movies via Netflix, or have a lot of real-time video chats, your data consumption is going to shoot up.

The best gauge is to check your recent telco bills on the amount of data juice you use on average per month. To save on data, you can also log on to Wifi networks wherever possible or download the music or video content on Wifi and then consume it offline.

What is an MVNO?

Mobile virtual network operators (MVNOs) ‘rent’ bandwidth and access to network services on the infrastructure lines and network from incumbents SingTel, M1 and StarHub at bulk wholesale rates. It then sets retail prices and packages accordingly, taking into account download speeds as well as network coverage.

What is ‘managed network speed’?

When a mobile plan promises ‘unlimited data’, check the fine print. It will usually say something like, ‘first 3GB of data at 4G speed, managed network speeds thereafter’ which basically translates to ‘your internet surfing based on the first 3GB of data will be fast but after that, expect both your network coverage and download speeds to become more spotty and slow down.’

Best SIM-Only plan for light data users: RedOne

Provider Data Price Talk Time SMS
RedONE 5GB S$8 300 mins 300 
VIVIFI Lite 3GB S$8.80 500 mins 20
Zero1 6GB Unlimited data S$6.90 150 mins, free caller ID 100 free outgoing, unlimited incoming

Special mention: TPG’s S$10 XL data plan

TPG, an Australian telco has since fully launched in Singapore with its 50GB plan that costs just S$10. Part of this package also includes 1GB of international data roaming at 1Mbps for India, Indonesia, Japan, Malaysia, Philippines, Taiwan and Thailand. If you go beyond 1GB, excess international roaming charges are billed at an affordable S$3 per 1GB.

Latest update: As of 4 March 2022, TPG’s 50GB plan’ has been further revised, costing only S$10 for 100GB of data. For users who feel that 100GB may be gratuitously excessive, they can opt for their 50GB plan that costs just S$8 (S$5 for the first 3 months) instead.


Launched in May 2019, redONE’s basic no-frills plan comes in at S$8. For that price, you now get 5GB, up from the previous 3GB, 100 minutes of talk time and 300 SMSes — ideal if you don’t consume a lot of data.

The big plus point of this MVNO is that users have free data roaming in Malaysia and no additional charges for calling and texting Malaysian numbers, making it ideal for those who live, work or visit Malaysia often.

For a limited time only, pay for your RedONE bill via Giro and get an additional 100 minutes of talk time for free. More details can be found here.


Awkward sounding name aside, VIVIFI is the latest MNVO launched in July 2019, using Singtel’s mobile network infrastructure.

For extremely light users there’s the VIVIFI Lite Plan, which is affordably priced at S$8.80 and comes with 3GB data, 500 minutes talk time and 20 SMS.

If you’re looking for something that gives you a little more data, VIVIFI has streamlined its VIVIFI PLUS series with a base plan providing 9GB worth of data, 350 minutes of talk time and 200 SMS for a monthly fee of S$9. It also comes with a caller ID and unlimited incoming calls.

If those perks aren’t enough, there are booster options to increase your data, talktime and SMS.

If you choose to not opt for boosters, then pay-per-use (PPU) charges will be applied when you use.


Zero1’s 6GB to Unlimited plan allows you to surf the first 6GB at a speed of 4G. Subsequently, it will be at a ‘managed’ network speed. As of now, the registration, SIM card and delivery charges are waived for new subscribers (depending on plan).

Due to popular demand, Zero1 has extended its promotion for this plan. Pay only S$6.90/month for this plan and get an additional 3GB for the first three months! However, a S$10.70 registration fee plus S$11.77 delivery fee will apply.


MyRepublic’s Lite Plan offers 6GB + boundless data for S$10 per month. It also comes with 300 talk minutes, 300 SMS and free caller ID. However, be prepared for slower connection speeds after exceeding 6GB usage. You can also opt for data boosters or add-ons to suit your needs.

China Mobile

China Mobile’s S$10/month SIM-only plan gives you 6GB data (can be shared between Singapore, mainland China and Hong Kong) and 10GB local data (for six months), 100 minutes of local talk time, 100 minutes overseas talk time (mainland China and Hong Kong, Malaysia, Indonesia, Thailand and USA), 100 local SMS, free incoming calls and free caller ID.

With 100 minutes of overseas talk time bundled with this plan, you won’t have to pay extra to connect with your loved ones who do not have data overseas.

Singtel’s GOMO package (stands for Go Out More Often) offers an affordable package of S$20/month for 20GB.

It is slightly more expensive than Circles.Life, but you get more data, 500 mins of talk time and 500 SMSes at only S$2 more per month. So if you make a lot of calls to landlines or fixed lines and still prefer to SMS, then Singtel’s GOMO package might be for you.

Limited-time promotion: Use GO100GB for extra 80GB worth of data for a total of 100GB for 6 months. Subsequently, data will drop back to 20GB for S$20 per month from the 7th month onwards. For new numbers and port-ins from other telcos only. Valid till 20 April 2022.


Zero1’s 80u mobile plan, which costs S$24.90 per month (U.P. S$29), allows you to surf the first 80GB at the higher 4G speed. Although it is an Unlimited Data Plan, be prepared for slower,  ‘managed’ network speeds after the first 80GB. As of now, the registration, SIM card and delivery charges are waived for new subscribers.

StarHub Giga

StarHub launched its Giga plan in response to Singtel’s GOMO and M1 offerings. For S$20 per month, it offers a sizeable 40GB of data and 500 minutes talk time and 500 SMS.

If you are looking for something cheaper, there’s another plan that offers 6GB of data, 500 minutes of talk time and 500 SMS for just S$10 a month.

What’s different about this plan is that any unused data can be rolled over to the following month, which makes this an attractive plan for those who have irregular usage of data every month.

M1 also offers a S$10 monthly bundle pack of an extra 50GB when you sign up for any of their SIM-only plans. Hence, you can round up your total data to a whopping 150GB per month with this extra bundle.


Promo code: SHARE32

Enjoy your VIVIFI Share plan at a discounted S$32 per month (U.P. S$40) for six months. Subsequently, your plan will revert to S$40 per month from the seventh month onwards.


Promo code: SUPER38

Upsize your base plan by paying an additional S$20/month for 100GB data with 4G rollover. If you combine it with their current promotional rate of S$18/month for your base plan, that means an amazing bargain price of S$38 per month for basically unlimited data!

However, this price is exclusive to number transfers and new registered numbers will have to top up an additional S$10 per month for this plan. Meaning, new registered numbers must pay S$48 per month to enjoy these similar perks.

Circles.Life has also introduced a new plan which offers 100GB at 4G speeds, 300 minutes outgoing talk time, free incoming talk time, and free caller ID for just S$38 per month. The best part about this plan? You can accumulate and rollover unused data up to 300GB.


With so many SIM-only mobile plans to choose from now, the days of being locked into a contract is now a thing of the past. When choosing a SIM-only plan, consider how much data, talk time and SMS you really need before making the switch. 

If you’re switching from a fixed contract to SIM-only, take note of any early termination penalties. Generally, the earlier you terminate the fixed contract, the heavier the penalty so calculate if what you’re saving by switching is enough to cover that amount. 

For example, if your early termination penalty is S$200, and you’re 6 months away from the penalty-free period, your new SIM only plan should be at least S$33.40 cheaper per month (S$200 divided by 6) than your existing contract plan.
