We’re all spoilt for choice when it comes to content we can consume on our mobile phones.
There is a wealth of news, articles, streaming music, online videos, virtual courses, apps and games available at the swipe of our fingers, as well as communicating with others via video calls, voice calls over data, and multimedia chats. Increasingly, we are also tapping on our mobile data for work.
All of these require data, and not everyone has the luxury of waiting until we are home or in the office to tap on a fast and secure Wifi connection.
To satisfy Singaporeans’ thirst for more data, various telcos in Singapore have begun to offer a variety of cheaper data plans, which has led to unlimited mobile data plans. These plans promise to put an end to situations where we have to watch our data usage closely, for fear of bursting the monthly limit and being charged hefty fees.
We compare unlimited data plans from across Singapore telcos to see which is the cheapest, as well as which gives us the most unthrottled data for our money. For this article, we’re going to assume that those who are interested are heavy data users – and only pick out plans that offer the most unthrottled data from each telco. We will also use regular prices and plan features, since promotional bonuses and discounts are either time-limited or only available to certain customers.

You May Not Need Unlimited Data With Large Data Plans
The downside to unlimited data plans is the inevitable throttling of data speed past a certain threshold. Depending on the provider, this throttling can bring your mobile streaming experience to a stutter at slower speeds, likely between 128 and 512kbps.
With large data plans (e.g. more than 50GB), you can be assured that you are receiving full speed data within this large data allocation. For most of us, this would be more than sufficient. You can find more options in our best SIM-Only plans for extreme data needs (with more than 50GB data at high speeds).

Comparison Of The Best Unlimited Data Plans In Singapore
With that in mind, here are the cheapest plans from each telco in Singapore that give you unlimited data.
| Plan | Monthly Cost For Unlimited Data | Fair Use Caveat | Notes |
| Circles.Life: Unlimited Plan (1TB with 5G Rollover) | $38.36 | Data speeds will be throttled at 125Kbps after 300GB | Plan comes with: – Unlimited talktime – No contract – 5G data rollover, up to 1TB |
| Singtel: Data X Infinity Add-On For Unlimited Data (using base XS plan) | $102.65 ($40.65 for Data X Infinity add-on + $62 for base XS plan) | Data speeds will be throttled at 1Mbps after exceeding an additional 50GB on top of any existing data coverage | Plan comes with: – 100 mins talktime – 100 SMS – Other perks (including McAfee Mobile Security, 3 months Disney+ Premium (12 mths contract) & 1 month Spotify, Entertainer and Straits Times One Digital) – Both the plan and add-on come with contract |
| MyRepublic: 250GB Data – 5G | $15.95 | Data speeds will be throttled at 384 Kbps after 250GB | Plan comes with: – 3GB data roaming (Msia, Indon, Thai) – 800 talktime – 800 SMS – Free caller ID |
| VIVIFI PLUS 20-5G | $11.50 | Data speeds will be throttled after 50GB. | Plan comes with: – 400 mins outgoing talktime – 200 outgoing SMS – 12-month contract |
| CMLink: Unlimited^ | $31.10 | Data speeds will be throttled to 512Kbps after 500GB | Plan comes with: – Including 40GB roaming data to China and HK, and 6GB to 7 APAC countries – 400 outgoing mins talktime – 400 SMS Free incoming calls – Free caller ID |
As you can see, even though VIVIFI offers the smallest full-speed data allocation of 50GB per month, it is the cheapest unlimited data plan for $11.50.
In general, unlimited plans would face throttling to lower speeds after using up the allocated data package. Video streaming would only be possible at low resolution, phone calls over data may be sketchy, and real-time gaming may be a source of frustration though it may be sufficient to send basic messages.
True heavy data users may prefer opting for MyRepublic’s Unlimited Data plan which gives 20GB per day at full speed (or 600GB for 30 days).
Circles.Life’s Unlimited Plan may be suitable for users who have inconsistent data usage – high in some months and low in others. The ability to roll over 1TB of unthrottled data can be attractive for those who tend to binge on mobile streaming for a period and take a break before their next binge.
If speeds matter to you, here’s how the telcos’ plans stack up from a Cost per GB at 5G speeds:
| Plan | Monthly Cost For Unlimited Data | Fair Use Caveat | Cost Per GB at 5G Speeds |
| Circles.Life: Unlimited Plan (1TB with 5G Rollover) | $38.36 | Data speeds will be throttled at 125Kbps after 300GB | $0.13 |
| Singtel: Data X Infinity For Unlimited Data (using base XS plan) |
$102.65 ($40.65 for Data X Infinity add-on + base XS plan: $36.68) | Data speeds will be throttled after 80GB (which is 50GB on top of existing 30GB data coverage with XS plan) | $1.28 |
| MyRepublic: 250GB Data – 5G | $15.95 | Data speeds will be throttled after 250GB | $0.06 |
| VIVIFI PLUS 20-5G | $11.50 | Data speeds will be throttled after 50GB. | $0.23 |
| CMLink: Unlimited^ | $31.10 | Data speeds will be throttled after 500GB | $0.06 |
As you can see, both MyRepublic and CMLink not only offer very generous 5G data limit but also some of the more affordable unlimited 5G plans.
That said, the rollover of 1TB at full speed for Circles.Life’s Unlimited Plan may be worth it for users who have more erratic usage patterns.
Another thing to note is also that some plans come with contracts, while others don’t. When choosing a plan, you should consider these factors and find a plan that fits your unique needs today and in the near future.
