[2024 Edition] Best Unlimited Data Mobile Plans In Singapore (Plus: Which Plan Gives The Most 5G Data Per Dollar?)

We compare telcos that give you the most data at 5G speeds.

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.

Best Unlimited Data Plan Contenders In Singapore

Circles.Life: Unlimited Plan (1TB with 5G Rollover)

To enjoy unlimited data with Circles.Life, you can subscribe to their Unlimited Plan (which is their base plan with the Unlimited Data add-on) for $38.36/mth. You will receive 300 GB (20 GB from your base plan and 280 GB from the add-on) at 5G speeds. Data usage thereafter will be throttled at 0.75mbps. Any unused unlimited data allowance can be rolled over to subsequent months, up to a maximum of 1 TB with 5G speed (excluding the base plan allocation of 20 GB). There is no contract, and you’ll enjoy unlimited talktime and access to Circle of Joy loyalty program.

Singtel: Data X Infinity Add-On (layered on top of base SIM-Only Plus 45 plan)

Singtel’s unlimited data add-on DATA X INFINITY, priced at $40.65 a month, is available for all their phone plans. A one-time sign up fee of $10.90 applies when you first sign up for the add-on and the minimum subscription is for 24 months.

For example, you can sign up for this add-on after applying for its base 5G SIM-Only Plus 45 mobile plan – which gives you 150 GB data at $36.68.

MyRepublic: Unlimited Data

While MyRepublic offers unlimited data for all their plans, they also offer an unthrottled Unlimited Data Plan. At $29.95/month, the Unlimited Data 5G plan offers 10 GB per day at full speed, followed by unlimited data at managed speeds. While MyRepublic doesn’t specify the exact managed speed, their Data-Only plan has a throttled speed of 1Mbps. You also enjoy 1,500 minutes of talktime, 1,500 SMS and caller-ID.

Alternatively, you can also opt for MyRepublic’s 5G Plus Plan at $19.95/mth with 200GB base plan data and unlimited data at managed speeds thereafter. The plan also comes with 1,200 minutes of talktime and free caller ID.


The VIVIFI Plus 20-5G plan comes with a 12-month lock-in at $19/month. The base plan offers 60GB local mobile data, and unlimited mobile data at managed speeds kicks in after that. You also get 400 outgoing local minutes and 200 outgoing local SMS with the plan.

Zero1: Z-One 5G Plus

The Z-One 5G Plus plan offers unlimited data at $20.08/mth. Data usage will be throttled after using up the 110GB data allocation. The plan also comes with free caller ID, 300 mins talktime and 100 free SMS.

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 60GB), 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 60 GB 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 0.75mbps after 100GB Plan comes with:
– Unlimited talktime– No contract
– 5G data rollover, up to 1TB
Singtel: Data X Infinity Add-On For Unlimited Data (using base SIM-Only Plus 45 plan) $71.21 ($40.65 for Data X Infinity add-on + $36.68 for base SIM-Only Plus 45 plan) Data speeds will be throttled after an additional 50GB on top of any existing data coverage Plan comes with:
– 1,000 mins talktime
– 1,000 SMS
– Other perks (including $100 phone voucher, 6-month free Disney+, free CAST Lifestyle Plus pack)
– Both the plan and add-on come with contract
MyRepublic: Unlimited Data $29.95 Data speeds will be throttled after 10GB a day Plan comes with:
– 1,500 talktime
– 1,500 SMS
– Free caller ID
VIVIFI PLUS 20-5G $19.00 Data speeds will be throttled after 60GB. Plan comes with:
– 400 mins outgoing talktime
– 200 outgoing SMS
– 12-month contract
Zero1: 5G Plus $20.08 Data speeds will be throttled after 110GB Plan comes with:
– 300 outgoing mins talktime
– 100 SMS
Free incoming calls
– Free caller ID

As you can see, the cheapest plan is from VIVIFI and Zero1, offering a 60GB and 110GB unlimited mobile data plan for $19.00 and $20.08 respectively.

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 10GB per day at full speed (or 300GB 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 0.75mbps after 100GB $0.38
Singtel: Data X Infinity For Unlimited Data (using base SIM-Only Plus 45 plan) $71.21 ($40.65 for Data X Infinity add-on + base SIM-Only Plus 45 plan: $36.68) Data speeds will be throttled after 210GB (which is 50GB on top of existing 150 GB data coverage with SIM-Only Plus 45 plan) $0.37
MyRepublic: Unlimited Data $29.95 Data speeds will be throttled after 10GB a day $0.10
VIVIFI PLUS 20-5G $19.00 Data speeds will be throttled after 60GB. $0.32
Zero1: 5G Plus $20.08 Data speeds will be throttled after 110GB $0.18

As you can see, Zero1 and MyRepublic offers not only the most 5G data but also the cheapest unlimited 5G plan with its Unlimited Data Plan.

However, the rollover of 1TB at full speed for Circles.Life’s Unlimited Plan may be worth it for users who binge occasionally.

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.
