SIMBA keeps things refreshingly straightforward: SIM-only, no-contract monthly plans built around generous data allowances. No device bundles, no lengthy commitments — just pick the data tier that suits you, stay as long as you like, and switch or cancel whenever you want. It's the kind of no-nonsense mobile setup that works well whether you're a data-hungry streamer or someone who just needs a reliable, affordable SIM for everyday Singapore life.
SIMBA also supports eSIM activation for compatible devices, letting you get connected without waiting for a physical card. All plans ride on Singapore's 4G and 5G infrastructure, giving you consistent speeds across the island.

SIMBA is an MVNO — it doesn't own towers. Instead, it leases capacity from M1's infrastructure. Here's what that means for real-world signal quality across the island.
SIMBA's biggest under-marketed asset is that its 4G signal comes straight from M1's own network — one of Singapore's three facility-based operators with decades of infrastructure investment. When you sign up for a SIMBA SIM, you're essentially accessing the same macro tower grid that M1 subscribers use, at a fraction of the price.
In the CBD and commercial districts, this translates to consistently fast speeds. Raffles Place, Marina Bay Sands, and the Orchard belt all benefit from dense small-cell deployments that M1 has built to support its enterprise clients. Our own spot-checks in these zones routinely returned 50–90 Mbps downloads.
HDB heartland coverage is where SIMBA punches well above its price point. M1's tower footprint extends deep into estates like Tampines, Woodlands, Yishun, and Jurong East. In our testing across five towns, voice calls on VoLTE were crisp and data speeds rarely dipped below 15 Mbps outdoors.
The MRT network is a more nuanced story. Above-ground and elevated stations are effectively full signal. Below-ground, performance depends heavily on which line you're on: the newer Downtown and Thomson-East Coast Lines have in-tunnel distributed antenna systems (DAS) that maintain usable LTE. The older North-South and East-West tunnel sections — built before in-tunnel LTE was mandated — can see signal drop significantly between stations.
Editor's note: Speed figures are based on informal spot-checks by the sirnba editorial team using a SIMBA SIM on a mid-range Android device. Results will vary by device, time of day, and specific location. This is not a sponsored analysis — sirnba is an independent guide.
M1 reports 98.7{ded80a9dda40582aaae20fdbab90276b750fbccd34063c571c912620122a050d} outdoor 4G population coverage across Singapore — and as an MVNO on that network, SIMBA inherits that footprint directly.
Dense small-cell deployment across Raffles Place, Marina Bay, Shenton Way, and Orchard. Speeds consistently 40–100 Mbps during peak hours.
M1's network penetrates HDB blocks reliably. Lift lobbies and corridors can see reduced signal in older towns like Queenstown and Toa Payoh, but common areas and living rooms hold strong.
Above-ground stations and inter-station stretches perform well. Underground tunnels on the older North-South and East-West lines can drop to 2–3 bars; newer DTL and TEL tunnels have better in-tunnel repeaters.
Modern condo developments with reinforced glass occasionally weaken indoor signal. SIMBA's VoLTE support helps voice quality. A Wi-Fi calling feature is on the roadmap.
Coverage in factory floors and warehouses in Tuas, Pioneer, and Boon Lay is functional but less dense. Outdoor industrial parks fare better than enclosed manufacturing facilities.
Macritchie, Bukit Timah, and East Coast Park are well-served by M1's macro towers. Expect 1–2 bar drops in the deepest trail sections of Central Catchment Nature Reserve.
