IoT SIM card for Singapore: multi-network M2M connectivity
Multi-network M2M SIM card for Singapore with access to Singtel, StarHub and M1 through data roaming agreements, switching automatically to the strongest available signal. Built for the all-4G/5G environment left by the 2G (2017) and 3G (2024) sunsets: 4G LTE, 5G, LTE-M and NB-IoT. Long-term permanent roaming operation, private APN, REST API and eSIM eUICC for large deployments, all managed from a single portal.
Why iot.cards for industrial IoT in Singapore
Access to Singapore's three major networks
The SIM connects to Singtel, StarHub and M1 through data roaming agreements and switches automatically to the strongest available signal. In an urban environment as dense and vertical as Singapore, that switching is critical for deep indoor penetration and for devices on high floors.
Permanent roaming without a regulatory ban
Singapore has no explicit regulatory ban on permanent IoT roaming, unlike markets such as Saudi Arabia or Brazil. Operation is governed by commercial roaming agreements and our SIMs operate there long-term. For very large permanent fleets there is also an eSIM (eUICC) local-profile route.
An all-4G/5G network environment
Singapore sunset 2G back in 2017 and 3G in 2024, making it one of the world's most modern network environments. Your devices must support 4G LTE, 5G, LTE-M, NB-IoT or Cat-1. NB-IoT is well deployed and suits underground utility metering and in-building sensors.
Southeast Asia regional hub
Assets and fleets moving across Southeast Asia (Malaysia causeway logistics, Indonesia, Thailand) stay connected on the same SIM, with no profile change and no extra logistics. Total coverage reaches 190+ countries and 750+ networks.
Private APN and static IP
Dedicated APN with an IPSec or WireGuard tunnel into your VPC, plus static IP as an add-on. Your meters, chargers and kiosks in Singapore send data directly to your platform without traversing the public Internet.
Unified portal and API management
Bulk provisioning by CSV, usage alerts and HMAC-signed webhooks from a single portal and a REST API. Tag each SIM by site, terminal or charging point and manage the full lifecycle without touching the device.
IoT coverage in Singapore
The SIM connects to Singapore's three major networks (Singtel, StarHub, M1) through data roaming agreements and switches to the best available signal. Outside Singapore, the same SIM operates on 750+ networks across 190+ countries, including Malaysia, Indonesia and Thailand.

Available technologies
Singapore completed its 2G sunset in 2017 and its 3G sunset in 2024. For new deployments, the modem must support 4G LTE, 5G, LTE-M, NB-IoT or Cat-1: hardware that only supports 2G/3G does not work in Singapore. For underground meters and in-building sensors, NB-IoT is the usual choice thanks to its penetration.
Capabilities for Singapore deployments
Beyond basic connectivity, the IoT SIM ships with the layers an industrial deployment needs:
Private APN with IPSec/WireGuard
Dedicated APN with your CIDR range and an IPSec or WireGuard tunnel into your VPC. Your meters, chargers and kiosks in Singapore send data directly to your platform without traversing the public Internet. Static IP available as an add-on.
View private APNeSIM eUICC for large deployments
2FF/3FF/4FF triple-cut, solderable industrial MFF2 and eSIM eUICC (SGP.02/SGP.32) form factors. For very large permanent fleets in Singapore, eUICC lets you load a local profile remotely without touching the device.
View IoT eSIMREST API for bulk management
Activation, pause, plan changes and consumption queries by API. Batches via CSV, usage alerts and HMAC-signed webhooks. Integrate the SIM lifecycle into your platform from day one.
API documentationPooled data across devices
Shared data pool across all the SIMs in the deployment: high-traffic devices compensate the ones that barely consume. Sized to the aggregate profile, not to the per-SIM worst case.

Pricing and lock-in
Billed in EUR, no lock-in. Each SIM carries a small monthly fee plus data usage. Three tariffs depending on traffic profile:
Pay-as-you-go (low usage)
From €0.005/MB per SIM. For sensors, meters and light telemetry sending a few MB per month.
High usage
From €1.50/GB. For gateways, kiosks, dashcams and traffic-heavy loads.
Enterprise
Custom tariff with SLA, dedicated private APN, eSIM eUICC local profiles and 24/7 support. For large or critical deployments.
Full detail at /planes/pago-por-uso and /planes/datos-compartidos. The SIM Test Kit (5 SIMs, 1 GB over 12 months, €15 VAT included) ships free to Spain and for €15 to the rest of EU+UK. The kit ships within Europe only: validate your device in your European lab, then deploy the SIMs in Singapore (roaming operation is identical).
Frequently asked questions about IoT SIM cards in Singapore
- Which Singapore networks does the SIM connect to?
- All three major carriers: Singtel, StarHub and M1, through data roaming agreements. The SIM switches automatically to the strongest available signal, with no manual intervention. In an urban environment as dense and vertical as Singapore, that switching makes the difference for indoor penetration and high floors.
- Is permanent roaming allowed in Singapore?
- Yes, in practice. Singapore has no explicit regulatory ban on permanent IoT roaming, unlike markets such as Saudi Arabia or Brazil; operation is governed by commercial roaming agreements and our SIMs operate there long-term. For very large permanent fleets we also offer the eSIM eUICC local-profile route at /productos/esim-iot. More context at /recursos/blog/roaming-permanente.
- Which technologies work after the 2G and 3G sunsets?
- Singapore sunset 2G in 2017 and 3G in 2024, so the device must support 4G LTE, 5G, LTE-M, NB-IoT or Cat-1. Modems that only support 2G/3G do not work in Singapore. For new hardware, Cat-1 or LTE-M is usually the best balance of cost and power consumption.
- Does NB-IoT work for underground meters and in-building sensors?
- Yes. NB-IoT is well deployed in Singapore and its extra link budget makes it suitable for meters in basements and service galleries, and for sensors inside concrete buildings. For loads with more traffic or mobility, LTE-M or Cat-1 is the alternative.
- How do I test from Europe before deploying in Singapore?
- With the SIM Test Kit: 5 SIMs with 1 GB over 12 months for €15 VAT included, free shipping to Spain and €15 to the rest of EU+UK. The kit ships within Europe only. The typical flow is to validate the device in your European lab and then deploy the SIMs in Singapore: roaming operation is identical.
- Private APN for my devices in Singapore?
- Yes. We provision a dedicated APN with your CIDR range and an IPSec or WireGuard tunnel into your VPC on AWS, Azure, GCP or your on-prem DC. Static IP is available as an add-on at /sim-iot-ip-fija. Detail at /sim-iot-apn-privado.
- Bulk management by API?
- Yes. POST /sims accepts batches in CSV or JSON with ICCID, plan and tags (site, terminal, charging point). Usage alerts and HMAC-signed webhooks integrate with your platform. Docs at /plataforma/api.
- Does the same SIM cover the rest of Southeast Asia?
- Yes. Assets crossing the causeway into Malaysia or moving through Indonesia and Thailand stay connected on the same SIM, with no profile change and no extra logistics. Total coverage is 190+ countries and 750+ networks.
- Support hours and time zone?
- The engineering team is in Seville (Spain) and works in English and Spanish during CET hours, which run 6 to 7 hours behind SGT. Async support runs on email and API status webhooks, so incidents do not wait for the time window. Enterprise plans include 24/7 support with SLA.
- Pricing and billing currency?
- Billing is in EUR. Pay-as-you-go from €0.005/MB for low usage and from €1.50/GB for high usage, with a small monthly fee per SIM and no lock-in. Detail at /planes/pago-por-uso.
