View Mobile PlanUnlimited data plans in Singapore are built for people who never want to watch a data counter: HD streaming on the commute, gaming on the go, hours of video calls, or tethering a laptop all day. For a flat monthly price the gigabytes stop mattering — but not all "unlimited" is created equal, and the fine print is where good and bad deals separate. The grid below compares every unlimited plan side by side so you can check the details before you commit.
Read the fine print: unlimited doesn't always mean full speed
"Unlimited" plans come in three flavours, and the plan page won't always shout about which one you're getting:
- Truly uncapped: full network speed with no volume trigger — the premium tiers.
- Fair-use throttling: full speed up to a usage threshold, after which speeds are reduced for the rest of the cycle.
- Speed-capped: unlimited volume, but throughput is limited to a fixed rate from the start — fine for music and SD video, frustrating for HD streaming and large downloads.
Before signing up, check the speed listed in our comparison and the provider's fair-use policy, and note that some plans cap hotspot or tethering data separately even when on-phone data is unlimited.
Who offers unlimited data in Singapore?
Among the majors, Singtel and StarHub both run unlimited tiers, while M1 and SIMBA compete hard with huge-allowance and unlimited-style offers that come and go. Value-focused brands like GOMO and CMLink prove unlimited doesn't have to mean expensive. The market shifts often, so treat the live grid above — not any provider's ad — as the source of truth.
Do you really need unlimited?
Be honest about your usage first: a 500GB+ plan or a 200–500GB plan is effectively unlimited for most people and often cheaper. Most unlimited plans now run on 5G and many are no-contract, so you can trial one and downsize later without penalty — and porting your number over is free, as our porting guide explains. Use the filters above to sort unlimited plans by price and speed and find your fit.
Frequently asked questions
What does "unlimited data" actually mean in Singapore?+
It means no fixed gigabyte cap — but not necessarily unrestricted speed. Some plans are genuinely uncapped, others throttle speeds after a fair-use threshold, and some are speed-capped from the start in exchange for unlimited volume. The terms and the speed listed on each plan tell you which type you're buying.
Are there unlimited data plans with no throttling?+
Yes — the premium unlimited tiers from the major networks run at full speed with no volume trigger. To verify before you sign up, check the speed shown in our comparison and search the plan's terms for a fair-use or speed-management clause; if a throttle threshold exists, it must be disclosed there.
What is the cheapest unlimited data plan in Singapore?+
Which providers offer unlimited data plans?+
Do unlimited plans run on 5G?+
Most current unlimited plans include 5G access, which is where unlimited shines — fast enough to replace home broadband for some users. You'll need a 5G handset for full speeds, though every plan still works fine on a 4G phone.
Is there an unlimited data plan for seniors?+
Senior-focused plans tend to prioritise simplicity and price over huge data, but some providers have paired senior eligibility with very generous or unlimited allowances. See our senior citizen plans page for what's available to users aged 60 and above.
Do I really need unlimited data?+
Only if you regularly stream HD video, game or tether without Wi-Fi. Check your actual monthly usage first — a 200–500GB or 500GB+ plan is effectively unlimited for most people and often costs less. Since many unlimited plans are no-contract, you can also try one and downsize later.
