The lowest prices come from SIM-only MVNO plans such as those from GOMO and giga!. Prices move with each promotion, so use the price filter above to find the current cheapest plan in this tier and weigh it against the data you get. For the absolute lowest across all tiers, see the cheapest plans page.
Generally yes. Under-$20 plans tend to offer some of the largest non-unlimited data buckets around, which suits heavy streamers and people who occasionally tether. If you regularly use your phone as a hotspot, compare plans under $30 or unlimited data options too.
Most do. At this price, fast 5G access is standard where coverage allows, and many plans bundle a healthy chunk of free roaming data for regional trips. Check each plan card for the exact roaming destinations and any speed caps.
For heavy daily streaming and occasional tethering, the large buckets in this tier are usually ideal. If you mostly browse and message, you can comfortably drop to plans under $15 and pocket the difference.
No. The bulk of under-$20 plans are SIM-only with no lock-in, billed monthly, so you stay free to switch. See all no-contract choices on our SIM-only plans page.
Yes. Number portability lets you bring your current Singapore number to a new provider, usually within a day or two, and you start the process during sign-up ā no separate call to your old telco required.
