Pricing refers to the minimum total cost for the first month.

Gone are the days when the mobile market was dominated by the three major telcos (Singtel, StarHub, and M1). Over the years, the market has seen a number of mobile virtual network operators (MVNOs) who’ve managed to offer similar—or even better—inclusions at a very comparable price range.

SIM-only plans are a great choice for the person who’s happy with their current handset or equally willing to buy their next smartphone outright. Compared to big providers, there tend to be more SIM-only plans on offer from MVNOs. And that greater range of plans leads to a great mix of competitive pricing, deals and discounts, and tight competition on the all-important data and roaming fronts.

Moreover, there are providers that offer capped speeds if you go over your monthly data allocation, so no bill shock. Scroll on to check our top picks of the best SIM-only plans in Singapore this month.

How we choose the best mobile plans in Singapore


At WhistleOut, we take the job of recommending mobile plans very seriously. That’s why we have a dedicated team that reads dozens of plan documents each week to spot hundreds of plan changes in our database.

We tend to lean towards SIM-only plans with no contracts because it’s easier to switch mobile providers when a better option comes along, but there's a wide array of factors we take into consideration:


Price

We consider overall price not just promotional pricing. 

We evaluate price in terms of first-year value, which helps separate great pricing from a limited-time promotion that may not offer better value in the long run. 



Data

To choose the best SIM-only deals we use included monthly local data.

This helps determine the overall dollar-to-data value. 

We also take into account if that data is 4G or 5G, with a preference for 5G.



Roaming

Singapore is a land of frequent flyers and travellers, so we prioritise plans with roaming inclusions

While the focus is on roaming data, extra points are given to plans with voice and SMS roaming
