All home fibre broadband internet plans in Singapore come with unlimited data. But that’s not the case with all SIM-only mobile plans.
Thankfully, certain mobile providers offer "unlimited" data, albeit usually with disclaimers. The best mobile plans with unlimited mobile data either cost extra, have capped speeds, or only include weekend data.
Unlimited data doesn’t technically mean you can use your mobile phone as a hotspot and download limitless data each month. Instead, unlimited data mobile plans are subject to a mobile provider’s fair-use policy. Even though some mobile providers in Singapore use managed speeds after a max-speed data limit has been reached, you may still be subject to provider intervention if you’re using what they consider to be too much data.
Best unlimited data mobile plan overall
We recommend starting your best unlimited data mobile plan comparisons with the GOMO 5G+ Asia Infinity plan. You'll get the best of both worlds with unlimited data, unlimited outgoing local minutes, unlimited local SMSes, unlimited data roaming across 18 destinations in Asia, plus 12GB roaming data to 50 other destinations. It typically costs $30.56 a month with a $2 upfront fee.
Note, GOMO's Infinity plans are subject to their Fair Usage policy of 1,024GB of local data. Asia roaming data is limited to 20GB full speed. Unlimited local calls and SMSes are also subject to the Fair Usage policy of 1,500 minutes and 1,500 SMSes.

Want unlimited data on a budget? If you're happy to forego 5G access, MyRepublic's 4G Rewardland Plan is your best bet.

Best unlimited data mobile plan for roaming
A handful of mobile providers offer unlimited data via managed speeds in Singapore. But what about unlimited data while roaming?
If you're travelling throughout Asia, our best pick overall (the GOMO 5G+ Asia Infinity plan) is your best bet. But for those planning a trip further afield, the GOMO 5G+ Global Infinity plan is an even better fit.
In addition to unlimited data (subject to fair use of 1,024GB) and unlimited local minutes and SMS (subject to fair use of 1,500), this globetrotting plan comes with unlimited worldwide roaming data (25GB full speed, lower speed thereafter) for use in 50 destinations across Asia, Europe, North America, and Oceania. It usually costs $50 per month plus a $2 upfront fee.

Best unlimited data mobile plan for weekends
Currently, only M1 offers unlimited weekend data, but it comes as an add-on for $6.12 per month. That said, all new SIM-only plans come with 12 months free. We recommend starting comparisons with the M1 5G SIM Only 350GB plan, which typically costs $17.95 every 30 days, with $3 off for the first three months for new port-ins. At the moment, it comes with a boosted 1TB of base data, 1,000 minutes of outgoing local calls and 1,000 outbound local SMSes.

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.
