The Basics
What Is an IoT SIM Card?
An IoT SIM card is a SIM designed for connected devices rather than phones. It authenticates sensors, routers, trackers, and other machines on cellular networks and prioritizes reliable, cost-effective data over voice and text. IoT SIMs are also called M2M SIM cards, and the two terms are interchangeable. Unlike consumer SIMs, IoT SIM cards are built for scale. They support bulk activation, pooled data plans, remote management, and networks built for machine data such as LTE-M and NB-IoT.
IoT SIM vs. Consumer SIM
A consumer SIM connects one phone to one plan with voice, text, and data. An IoT SIM connects fleets of machines to data plans sized for machine traffic, managed centrally through a platform like VOYAGER. Same chip technology, completely different job.
Choose Your SIM
Single-Carrier or Multi-Carrier?
Choose the Right IoT SIM
Most deployments don't fail because of hardware. They fail because the connectivity behind them doesn't fit. The right choice depends on where your devices operate and how much network flexibility they need.
Single-Carrier SIMs
One network, one plan, predictable pricing.
Single-carrier IoT SIMs are the right fit when your devices operate in a known coverage area on a proven network. Datablaze partners directly with T-Mobile, Verizon, AT&T, Rogers, and more, so you get carrier-direct rates with platform-level management.
Best for fixed deployments, regional fleets, and cost-sensitive applications.
DB1 Multi-Carrier SIM
One SIM, every carrier.
The DB1 connects across multiple carrier networks from a single SIM using eUICC and multi-IMSI technology. Devices switch to the best available network automatically on compatible devices, without a SIM swap or field visit.
Best for mobile assets, nationwide deployments, and devices that can't afford downtime.

IoT Data Plans
IoT Data Plans Built Around How Devices Use Data
IoT data plans are cellular subscriptions sized for machine traffic instead of consumer usage. Devices that transmit kilobytes per day shouldn't pay smartphone rates, and high-bandwidth devices shouldn't throttle mid-deployment. Datablaze offers flexible IoT data plans across multiple carriers, including pooled data options that share a single allowance across a group of devices. Usage, overage alerts, and billing are visible in real time in VOYAGER.
VOYAGER By Datablaze
Every SIM, Every Carrier,One Platform
VOYAGER manages Datablaze multi-carrier SIMs, single-carrier SIMs, and your connected devices in a single platform.
- Activate, suspend, or terminate IoT SIM cards
- Send alerts to users before exceeding limits
- Visualize historical and real-time data usage
- Comprehensive API suite
Security
Secure Connectivity for Remote Devices
Machine data shouldn't travel the public internet unprotected. Datablaze IoT SIMs support the connectivity controls remote deployments depend on.
Static IP Addresses
Datablaze IoT data plans support both dynamic and static IP addresses. A static IP gives you a reliable way to reach devices that need remote maintenance, pushed updates, or configuration changes.
VPN Connectivity
For sensitive data, devices can connect through a VPN. Traffic is encrypted end to end, keeping machine data off the public internet and away from interception.
Private APN
A private APN acts as a dedicated gateway between your devices and your network, with custom authentication and traffic rules that keep your fleet isolated from public traffic.
Form Factors
SIM Card Sizes for Every Device
Wireless devices are designed to accept a specific SIM size. Removable Datablaze IoT SIM cards ship as a 3-in-1 card that works in any of the three plug-in sizes, while the MFF2 is soldered in place at the factory.
2FF (Mini) · 25mm × 15mm · The original standard, used in larger wireless devices.
3FF (Micro) · 15mm × 12mm · About half the size of the mini, common in mobile devices.
4FF (Nano) · 12.3mm × 8.8mm · The smallest removable form factor, built for compact devices.
MFF2 (Embedded) · 6mm × 5mm · A chip-format SIM soldered directly to the device’s circuit board during manufacturing. With no tray or socket to fail, it withstands vibration, moisture, and extreme temperatures, making it the standard for industrial IoT devices.
eSIM · Not a size but a capability. An eSIM-enabled SIM can download and switch carrier profiles remotely, without a physical swap. Available in both removable sizes and the embedded MFF2 format.

FAQs
IoT SIM Card FAQs
What is the difference between an IoT SIM card and an M2M SIM card?
These terms are used interchangeably. IoT, or Internet of Things, refers to devices that typically require little human interaction, such as sensors, smart devices, wireless routers, and IO switches. M2M, or machine-to-machine, is often used when referring to SIMs deployed in machines. The SIM cards themselves are typically identical.
What is the difference between a single-carrier and multi-carrier IoT SIM card?
A single-carrier IoT SIM connects to one carrier network, such as T-Mobile, Verizon, or AT&T. It offers predictable pricing and performance, and works well when devices stay within a known coverage area. A multi-carrier IoT SIM can connect to multiple carrier networks from a single SIM. If one network is weak or unavailable, the device switches to another automatically. Multi-carrier SIMs fit mobile assets, wide-area deployments, and devices where downtime is not acceptable. Both SIM types are available from Datablaze and are managed in the same VOYAGER platform.
What are the differences between M2M SIM cards and traditional consumer SIM cards?
Traditional SIMs are made for consumer products such as smartphones and tablets. M2M SIMs are typically subscribed to NB-IoT, CAT-M1, LTE, and 5G business data accounts in bulk. Since most IoT applications only transmit data, voice is rarely included. Some M2M SIMs are offered as industrial SIM cards, designed to withstand wear, higher vibration, and more extreme temperatures.
Can I use a regular SIM card in an IoT device?
In many cases a consumer SIM will physically fit and connect, but it isn't built for the job. Consumer plans are priced for smartphone usage, lack centralized management, and often prohibit machine use in their terms of service. IoT SIM cards provide data plans sized for machine traffic, bulk management through a platform, and options like static IPs and private APNs that consumer plans don't offer.
How much does an IoT SIM card cost?
IoT SIM pricing depends on the data plan, not the card. The main factors are how much data each device uses, the carrier and coverage area, the number of SIMs deployed, and whether data is pooled across the fleet. Low-usage sensors can cost a few dollars per month, while high-bandwidth devices are priced closer to broadband plans. Datablaze provides pricing based on your deployment, and every plan includes access to VOYAGER.
What sizes are M2M SIM cards available in?
SIM cards come in three standard sizes: 2FF (Mini, 25mm × 15mm), 3FF (Micro, 15mm × 12mm), and 4FF (Nano, 12.3mm × 8.8mm). Many SIMs ship as a triple-cut card with all three sizes in one. The correct size is determined by the device or modem manufacturer. If you're not sure which size you need, check with your device manufacturer or SIM provider.
What is a steered IoT SIM card?
Carriers often allow their SIMs to roam across other networks when signal is poor or nonexistent. A steered SIM always connects to the primary provider's network, even when the signal is weak. If no coverage is available, the SIM is steered to the least expensive available network. A non-steered SIM lets the device choose which network to connect to, usually based on the strongest signal detected.
What is an APN and why do IoT SIMs need a private APN?
An APN (Access Point Name) is the gateway between the cellular network and the internet. It handles authentication and security protocols for the SIM and manages what type of traffic can reach the device. Public APNs are provided by most mobile network operators with basic configurations. A private APN lets you customize network settings and authentication, isolating your devices from public traffic for stronger security.
What is a static IP address and why would an IoT SIM card need one?
Most connected devices use dynamic IP addresses assigned by the network, which can change every time the device connects. A static IP assigns one fixed address that never changes. Static IPs are used when a device needs to be securely reached for monitoring or maintenance regardless of location, such as remote CCTV cameras in security deployments.
