[2019 Edition] Best Unlimited Data Mobile Plans In Singapore (Plus: Which Plan Gives The Most 4G Data Per Dollar?)

With so many telcos and unlimited data plans, we compare which is the cheapest – and which gives you the most data at 4G 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, longform articles, streaming music, online videos, virtual courses, apps and games available at the swipe of your finger, as well as communicating with others via video calls, voice calls over data, and multimedia chats.

All these great use cases all require data, and not everyone has the luxury of waiting until they are at home or in the office to tap on a fast and reliable Wifi connection.

To satisfy Singaporeans’ need for data, the various telecommunication companies (telcos) in Singapore have begun to offer increasingly cheaper data plans, culminating in unlimited data plans.

These plans promise to put an end to situations when we have to watch our data usage closely, for fear of bursting the limit that month, or be charged hefty fees.

Today, we’ll examine and compare unlimited data plans from across the telcos and see which is the cheapest, as well as which gives you the most unthrottled data for your money. Regular prices and plan features are used, since promotional bonuses and discounts are either time-limited or only available to certain customers.

 Best Unlimited Data Plans In Singapore Compared

With that in mind, here are the cheapest plans from each telco in Singapore that give you unlimited data.

As you can see, if you don’t care about speeds and want the cheapest plan with unlimited data, the Zero1 1GB To Unlimited Data is the clear winner, though realistically, you’ll be pretty limited with what you can do after that 1 GB of 4G speeds is used up. 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.

If speeds matter to you, here’s how the telcos’ plans stack up from a Cost per GB at 4G speeds:

Plan  Monthly Cost For Unlimited Data Fair Use Caveat Cost Per GB at 4G Speeds
Circles.Life Base Plan $38 Data speeds will be throttled after 40 GB $0.95
M1 mySIM3 98 $98 Data speeds will be throttled after 50 GB $1.96
Singtel Combo 3 $108.80 Data speeds will be throttled after 50 GB $2.17
StarHub $25 SIM Only Plan $45 Data speeds will be throttled after 55 GB $0.81
Zero1 9GB To Unlimited Data $39.90 Data speeds will be throttled after 9 GB $4.43
Zero1 1GB To Unlimited Data $13.90 Data speeds will be throttled after 1 GB $13.90
Zero Mobile Zero X $59.95 Data speeds will be throttled after 30 GB $1.99


As you can see, when you take 4G data into account, Zero1’s 1GB To Unlimited Data suddenly becomes the most expensive. In this situation, StarHub’s StarHub $25 SIM Only Plan plus 50GB with Worry-free data add-on gives you the most 4G data for your buck at $0.81. This would be suitable for power users who also like the peace of mind that unlimited data plans provide.

In our comparison, we’ve only looked at the plans from a purely mobile data perspective. Each of the plans offer a mix of talktime, free income calls, caller ID, and other value-added services. When choosing a plan, you should take these into consideration and find a plan that fits your unique needs today and in the near future.
