DB1 Multi-Carrier SIM
One SIM.
Every network.
Zero downtime.
Global IoT means juggling dozens of carriers, contracts, and compliance rules, and a dead network means a dead device. The DB1 switches between networks automatically based on coverage, policy, and compliance, so your devices stay online everywhere, managed from one platform.

What Is a Multi-Carrier SIM
One SIM.
Many networks.
Total flexibility.
The DB1 gives you one global SIM that intelligently and automatically connects to the best available network. It carries multiple carrier identities and switches between them across roaming, regional, and local IMSIs, all managed from a single platform.
Stay online, stay compliant, and keep full control of every device, everywhere it goes.
Autonomous over-the-air network switching
Global coverage through a local carrier
Integrated eSIM (eUICC) support
Any GSM technology: 4G/LTE, 5G, NB-IoT, LTE-M
Built to Keep Devices Online
Resilient connectivity that adapts on its own
The DB1 carries multiple carrier identities on a single SIM and switches between them automatically based on coverage, policy, and compliance.
When a network drops
Autonomous IMSI switching
Devices switch to the strongest available network on signal loss, with no reboot and no truck roll. Uptime holds even when a carrier fails.
When you cross a border
Local-carrier connectivity worldwide
The DB1 connects through a local carrier in over 220 countries, mitigating permanent-roaming restrictions so devices operate reliably in strict-regulation markets.
When you scale to new regions
One global SKU in VOYAGER
A single SIM works anywhere with no per-region replacements. One contract, one platform, one invoice, instead of a carrier stack that grows with every market.

Profiles updated over the air. No SIM swap required.
eUICC Remote Provisioning
Change carriers without touching the device
Sending a technician to swap a physical SIM does not scale, and it is impossible once devices are sealed, buried, or moving. With eUICC-enabled SIMs, IMSI profiles are remotely managed for dynamic provisioning and over-the-air updates.
No more maintaining multiple physical SIMs, and no onsite visits to swap cards. These innovations deliver unmatched flexibility, scalability, and security, improving the efficiency of every IoT deployment.
VOYAGER by Datablaze
Stop managing carriers one by one
The SIM keeps devices online. VOYAGER is where you actually run the deployment. No more logging into separate carrier portals, guessing at usage, or reconciling a stack of invoices. Every DB1 SIM, IMSI profile, and data plan lives in one platform, alongside any single-carrier SIMs you already manage.
Set the rules once and VOYAGER enforces them automatically, everywhere your devices go.
Unified device & SIM management
One interface to manage connected devices and SIMs together, across multi-carrier and single-carrier subscriptions.
Remote SIM control
Activate, suspend, or update SIMs and profiles over the air, one device or a fleet at a time.
Usage visibility
See historical and real-time data usage per SIM, group, or region. No more guessing before the invoice lands.
Overage alerts
Get notified before a SIM crosses its limit, so surprises never reach the invoice.
Consolidated billing
Every carrier account on one clear invoice, with Excel exports and breakdowns by label or group.
Multi-tenant management
Run separate entities from one platform. Each tenant sees only what it should, and costs pass through cleanly.
Faster deployment
Reduce the time to select data plans and activate SIMs with a single all-in-one solution.

GET A DEMOWho It's For
Built for teams deploying IoT at global scale
Enterprises with global IoT
Deploy across 220+ countries on one global SKU, maximize device uptime, and stay compliant in high-regulation markets.
IoT service providers
Deliver reliable cross-border connectivity from a single SIM and platform, without stacking carrier contracts and portals.
Fleet & asset operators
Keep mobile assets connected as they cross networks and borders, with automatic switching and location-aware visibility.
Security & Compliance
Remove the risk before it reaches your data
Machine data on the public internet, and devices operating under foreign roaming law, are liabilities. The DB1 closes both gaps by design.
Private APN & VPN
A private APN and end-to-end VPN keep traffic off the public internet, with custom authentication that isolates your fleet.
Static IP addresses
Reach devices reliably for remote maintenance, pushed updates, and configuration changes, wherever they sit.
In-country data & GDPR
Connectivity through a local carrier mitigates permanent-roaming restrictions, and data stays within the originating country to adhere to privacy laws like GDPR.
FAQs
Multi-Carrier SIM FAQs
What is a multi-carrier SIM card?
A multi-carrier SIM card lets you switch between different mobile network carriers without changing the physical SIM. It offers flexibility and convenience by enabling access to multiple networks on a single SIM.
How does a multi-carrier SIM card work?
A multi-carrier SIM contains profiles for multiple mobile network operators, each referring to an IMSI. When inserted, the device detects the available networks and connects to the appropriate one, and you can switch networks without swapping the physical SIM.
How is the DB1 different from a single-carrier SIM?
A single-carrier SIM connects to one network and goes dark if that network drops. The DB1 carries multiple carrier identities and switches automatically on coverage, policy, and compliance, so devices stay online across networks and borders.
Does the DB1 work with eSIM (eUICC)?
Yes. The DB1 is an eSIM and multi-IMSI solution. eUICC-enabled SIMs store multiple profiles and support remote SIM provisioning, so profiles can be managed and updated over the air.
How do you change the carrier on a SIM?
Traditional SIMs require getting a new SIM and manually inserting it. The Datablaze DB1 uses eUICC technology to store multiple profiles and enable remote SIM provisioning, so you can change carriers over the air.
Do I need special software or apps to use it?
No. Carrier selection is either automatic based on the SIM provider's settings, or managed by the provider or user in the cloud-based VOYAGER administration portal.
Is my device compatible with the DB1?
Most unlocked GSM or LTE-compatible devices are compatible. It is always a good idea to confirm with your device manufacturer or carrier before deploying at scale.
