Best SIM-Only Plans for Light, Moderate, and Heavy Data Users | SingSaver

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.  

Last updated on 6 October 2021. SIM-only mobile plans and promotions are subject to change without prior notice.

Entry of new players flood the market

The three latest mobile virtual network operators (MNVOs) to join the battle are redONE (through StarHub’s mobile network), ViViFi (SingTel’s mobile network) and Grid Mobile (a new joint venture between SingTel and ST Telemedia),

Add these three 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 land lines. 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. The S$5/month plan offers 2GB of data, 50min talk time (incoming and outgoing, and free caller ID), and 25 SMS. 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.

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 an average of 2.7GB a month — up nearly 23 per cent from 2.2GB a month the previous year. 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 a 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.’

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.

Sign-up offer: TPG is offering new applicants a 100GB and 130GB plan for S$10 and S$18 respectively, up from the usual 50GB and 80GB you’d receive instead. This promotion is valid for a limited time only and if you’re a current subscriber, fret not because you’ll automatically receive the upgrade upon renewal.

redONE

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.

VIVIFI 

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 launched the VIVIFI Plus (6GB) and VIVIFI Plus (10GB). Both plans are bundled with 350 minutes talk time and 100 SMS, caller ID and unlimited incoming calls.

Sign-up offer: Use promo code PLUS850 to get VIVIFI’s PLUS plan at S$8.50/month for six months. This plan comes bundled with 6GB data, 350 minutes talk time, 100 SMS, and free incoming calls, SMS and caller ID. Registration, SIM and actions fees have also been waived. Promotion is for a limited time only and lines must be activated by 31 October 2021.

Zero1

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$9.90/month instead of S$13.90/month for this plan and get an additional 3GB for the first three months! However, a S$10.70 registration fee will apply.

MyRepublic 

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.

If you sign up now, you’ll have the option to add 10GB of data for only S$1.99/month (U.P. S$5.99/month). Promotion valid for a limited time only.

China Mobile

Recently launched earlier this year, China Mobile’s S$10/month SIM-only plan gives you 6GB data (can be shared between Singapore, mainland China and Hong Kong), 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

For S$20/month, Singtel offers you 3GB of data for its base plan. Do note that his plan does not come with any contract, talk time, or SMS so it’s a pretty bare bones offer.

  • For moderate users: Priced at S$17.90/month, this plan gives you 20GB of data, 120 mins of talk time, 50 SMS, free caller ID and incoming calls.
  • For heavier users: Priced at S$24.90/month, this plan gives you 40GB of data, 200 mins of talk time, 200 SMS, free caller ID and incoming calls. In addition, this plan also comes with 1GB worth of roaming data in Malaysia per month (for new users only).

Circles.Life goes for S$18/month for 20GB. The best part is that you can easily and instantly customise your plan via the Circles.Life app.

For a limited time only, Circles.Life is offering those transferring their number to Circles.Life unlimited data, incoming calls and outgoing calls for an entire month. It will revert to 20GB data, 100 minutes talk time and 25 SMS after the first month.

GOMO 

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, and an additional 200 mins of talk time and 200 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.

Sign-up promotions:

  • Use promo code BEST70 to enjoy 70GB of data , 500 mins of talk time and 500 SMSes at S$18 for the first month.

Zero1

Zero1’s 30u mobile plan, which costs S$24.90, allows you to surf the first 30GB at the higher 4G speed. Although it is an Unlimited Data Plan, be prepared for slower,  ‘managed’ network speeds after the first 30GB. 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.

Sign-up promotion: Valid from 7 to 10 October 2021, get a generous 70GB of data for only S$18/month. More details can be found here.

Sign-up promotion: New MyRepublic subscribers get an additional 28GB (to be used within the first eight months) on top of the usual 50GB. Valid for a limited time only.

Circles.Life has also introduced a new plan which offers 100GB at 4G speeds, 100 minutes talk time and 25 SMS for the same price. However, you’ve got to be a new user to enjoy this promotion and the prices goes back to S$48/month after the first year. Not to mention, this plan also allows you to roll over up to 300GB of high speed 4G data that you have leftover each month.


Conclusion

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.
