What Is A No Contract SIM-Only Plan?
SIM-Only plans are postpaid plans that package data, talk time, and SMSes at a fixed monthly cost.
This way, you can focus on what is most important to you — which is probably data.
They function like traditional mobile phone contracts, BUT you’re not locked into any minimum contract period.
This means that you are free to switch telcos or mobile plans anytime you like without incurring any penalties.
Can I Go SIM-Only And Keep My Number?
Yes! In fact, new port-ins are highly encouraged due to better deals and freebies if you are switching telcos. All you need to do is fill up the sign-up form with your existing number and the telco will settle the rest.
Which SIM-Only Plan Is Best in Singapore?
The best SIM-Only plan really depends on how much data you’ll need. Here’s how we would choose a mobile plan:
- Look at your latest telco bills to check how much data you’ve been using monthly (and how much talk time and SMS-es if you’re old school like that)
- Narrow down a few plans from our list of SIM-Only mobile plans that cater to your data needs
- Consider the quality of service, user experience, and mobile reception of the company (don’t just chase the highest GB per dollar as the service may not be as good)
- We’ll cover reception briefly in this article. Alternatively, check out reviews on Seedly of the respective companies to get a better sense of user experience.
- For those who care a lot about user experience, consider looking at mobile app reviews on the Apple/Google Play store.
- After that, go forth and pick a plan knowing that you’ve done your research/due diligence and getting the most out of your money!
Which Singapore Telco Has The Best Reception?
There are four Mobile Network Operators (MNOs) in Singapore:
And these are the 12 Mobile Virtual Network Operators (MVNO), aka virtual telcos in the market right now:
- Changi Mobile
- Circles.Life
- CMLink (China Mobile)
- Geenet
- giga!
- GOMO
- heya
- MyRepublic Mobile
- redONE
- VIVIFI
- Zero1
- ZYM Mobile
Here’s a look at who’s on which MNO’s network:
Mobile Network Operator | Mobile Virtual Network Operator (Which MNO do they rent bandwidth and network services from?) |
---|---|
Singtel | CMLink |
GOMO | |
heya | |
VIVIFI | |
Zero1 | |
ZYM Mobile | |
Starhub | giga! |
MyRepublic | |
redONE | |
M1 | Changi Mobile |
Circles.Life & MyRepublic | |
Geenet | |
Gorilla Mobile | |
SIMBA (formerly TPG) | - |
Also, here is how the telcos compare in terms of coverage according to the Infocomm Media Development Authority (IMDA)’s latest Q4 2022 (October – December) 4G quality of service performance results:

Singtel, M1, StarHub or SIMBA?
But while IMDA’s report shows that the MNOs are comparable, this doesn’t necessarily translate to good connection during actual usage. SIMBA for example has been known for a pretty terrible internet connection.
Meanwhile, Singtel seems to offer the best coverage based on reviews.
So, if you want reliable coverage, I’ll probably avoid SIMBA even though they have some of the best bang-for-buck plans, and go for Singtel or the MVNOs riding on its network.

Recommended: Zero1 Starter
Being the cheapest on the list, the Zero1 Starter plan (previously known as 6u) offers 6GB for just $7, and you get unlimited throttled data thereafter with a decent number of minutes/SMSes.
Plus, Zero1 utilises the Singtel network, which provides the most coverage out of all the other operators.
Best value: redONE Perfect10
SIMBA used to reign this spot for our past iterations. But this time, redONE has come out top with the redONE Perfect10! It offers 100GB for $10, plus more talktime and SMS than SIMBA’s 100GB plan.
Moreover, redONE has been getting rave reviews from our Seedly community, so it’s definitely a plan to check out:
However, you should also know that SIMBA is relatively new and is using its own network. So be sure to check out reviews before you make the switch.
