View Mobile PlanMobile plans under 100GB cover the everyday sweet spot for most Singaporeans. Under 100GB a month is plenty for browsing, messaging, social media, music and a healthy amount of video streaming — without paying for huge allowances you will never touch.
Who needs this much (or this little)? If you are mostly on Wi-Fi at home and work and use mobile data for navigation, chat, social feeds and the occasional stream, a plan in this range fits perfectly. It is the most cost-effective band in Singapore, packed with no-contract SIM-only deals from MVNOs like GOMO and giga! as well as the major networks.
A rough guide to data use under 100GB:
- Browsing, chat and email: Uses very little — even the smaller plans here last the month easily.
- Daily music and social video: Comfortably handled by mid-range allowances in this band.
- Regular HD streaming: Lean toward the top of this tier, near the 100GB mark.
Frequently asked questions
Is under 100GB enough data per month?+
For most people, yes. If you are usually on Wi-Fi at home and work and rely on mobile data for browsing, chat, navigation, social media and some streaming, under 100GB comfortably lasts the month. Only heavy HD streamers and frequent hotspot users tend to need more.
What's the cheapest plan under 100GB?+
The lowest prices come from SIM-only MVNO plans such as GOMO and giga!. Use the price filter above to find the current cheapest plan in this data band, then compare the exact allowance and roaming included. The cheapest plans page ranks them all.
Do under-100GB plans include 5G and roaming?+
Many do. Plans in this band frequently include 5G access where coverage exists, and a good number bundle free roaming data. Roaming destinations and any speed caps vary by provider, so check each plan's terms before signing up.
How much data do I actually need?+
If you stream casually and browse on the go, a mid-range allowance under 100GB is ideal. If you tether or stream HD heavily, step up to 100GB to 200GB plans or consider unlimited data for total peace of mind.
Can I keep my number and avoid a contract?+
Yes on both counts. Most plans in this range are SIM-only with no lock-in, and Singapore's number portability lets you bring your existing number across during sign-up, usually within a day or two. See all flexible options on our SIM-only plans page.
