Seize IoT Opportunities, Deploy Faster

Smart City

For dispersed-node deployments — smart streetlights, air-quality sensors, parking, waste collection. DTG Core C1 / C4 modules with iSIM multi-carrier auto-switching: no per-unit SIM provisioning, one-click OTA from the back end.

IoV Applications

For vehicle OBUs, fleet management, and emergency-rescue communication. iSIM international roaming + DTG Core C4 with pre-installed Tailscale mesh VPN: zero-dropout cross-border connectivity, no SIM swapping, devices auto-join the tailnet on power-up.

Smart Traffic

For traffic-light control, tunnel sensors, and roadside monitoring in sealed outdoor enclosures. DTG-720-iSIM triple-WAN failover (~12 s switch) plus three-tier remote-management channels — primary downlink failure auto-falls-back.

Process Upgrade

For factory SCADA/IIoT, production-line connectivity, and substation monitoring. RS-485 / CAN Bus industrial I/O + Modbus RTU→TCP gateway + 4G backup — disconnects backfill data on reconnect.

FAQ

Frequently Asked Questions

Common questions about iSIM technology

QiSIM vs eSIM — which is better for IoT deployment?+
iSIM integrates SIM functionality directly into the device's main chip, eliminating the need for a separate SIM slot or eSIM chip. Smaller, cheaper, and more secure than eSIM — ideal for mass IoT deployments in smart cities, connected vehicles, and industrial automation.
QWhat scenarios are Digitalent iSIM modules suitable for?+
Smart city infrastructure, connected vehicles, industrial automation, environmental monitoring — any IoT scenario requiring secure, long-term connectivity at scale.
QWhat is DTG-720-iSIM and how is it different from a regular industrial computer?+
DTG-720-iSIM is Digitalent's flagship industrial computer with a native built-in XS4G01 iSIM module and dual-system Out-of-Band (OOB) management architecture. It boots and connects to 4G without a physical SIM card, and OOB allows remote recovery even when the main system is down — capabilities standard industrial computers cannot provide.
QWhich carriers does iSIM support, and does it roam internationally?+
The XS4G01 module is MVNO-authorized and supports switching across Taiwan's three major carriers (Chunghwa Telecom, Taiwan Mobile, Far EasTone) plus 100+ countries roaming, without swapping SIMs or reconfiguring.
QWhat does Digitalent's iSIM offering include?+
MVNO-authorized iSIM modules (XS4G01 series), complete devices (DTG Core C1/C4, DTG-720-iSIM), technical integration consulting, and end-to-end IoT deployment support from hardware to cloud.
