ACS SmartSIM keeps delivery handhelds, field tablets, phones, and POS backup online across AT&T, T-Mobile, and Verizon — automatic failover so the stop finishes.
Auto-failover to Verizon — 0 downtime
Delivery handhelds, field tablets, phones, POS backup — when the signal drops mid-route, the stop stalls. That's lost money, not an IT ticket. ACS SmartSIM keeps the crew moving across AT&T, T-Mobile, and Verizon.
The scan is done. The signature is on the glass. The upload sits there. No proof of delivery, the next stop waits, and dispatch is already asking where the driver is. ACS SmartSIM fails over so the handheld finishes the stop.
Tech is on site. The tablet or phone drops the work order, photos won't attach, customer sign-off won't send. Billable time ticks until the device is back online — automatically, on the next carrier.
You know the ones. Every route through them generates a ticket. Are the towers down, or is it just coverage? For an outdoor coverage check, see the FCC mobile map: broadbandmap.fcc.gov → Mobile.
ISP or fiber goes dark and the store is stuck — registers, scanners, cameras. A truck roll is hours. ACS SmartSIM keeps POS and backup lines on multi-carrier cellular until the circuit is back.
ACS SmartSIM solves all of it — one SIM, three carriers, automatic failover. The handheld finishes the stop, the job closes, and the register doesn't wait on a truck roll.
SmartSIM pairs with any WAN-capable, SIM-enabled hardware — tablets, handhelds, laptops, and IoT devices — and connects them to hundreds of networks through intelligent carrier switching.
When a carrier drops, SmartSIM switches to the next available network automatically — no manual intervention, no reboot, no profile swaps.
Deep packet inspection at the network layer applies virus, malware, and content filtering across every connected device.
Real-time visibility into uptime, network performance, and the average number of carrier switches per SIM — all in one portal.
Eliminate juggling multiple carriers, SIM types, contracts, and invoices. SmartSIM simplifies procurement and plan management.
US-based engineers troubleshoot at the network level — not just your device. A 24/7/365 hotline and global NOC resolve carrier issues before you ever open a ticket.
4G/LTE in 160+ countries and 5G in 48. AT&T, T-Mobile, and Verizon at home, plus seamless coverage wherever your fleet roams.
Cuts, ISP outages, and building issues take primary circuits offline. ACS SmartSIM keeps POS, phones, and cloud apps up on multi-carrier cellular until fiber is back — same auto-failover, no truck roll.
Nobody buys 600 carriers. They buy the delivery that finishes — and the stop that doesn't stall.
Multi-carrier resilience doesn't cost more. SmartSIM is priced comparably to what you're already paying one carrier — for triple the reliability.
When something goes wrong, US-based support diagnoses the network itself — not just your device — and fixes carrier issues before they reach your team.
While competitors scrambled during a massive nationwide carrier outage, SmartSIM customers never noticed. Their fleet never went dark — and no one had to explain a thing.
Florida retail stores kept operating while Hurricane Ian disrupted multiple carrier networks.
A foodservice distributor ended dead zones for warehouse and delivery drivers across North America — no more stranded trucks, no more 'we lost signal' excuses.
As carriers retire legacy systems, SmartSIM devices keep working — no costly field visits required.
The number of SIM-enabled devices is exploding — fleet trackers, retail scanners, field-service handhelds, IoT sensors. Cell towers and backhaul were planned for a fraction of this load. In high-growth metros, new developments outpace new towers by years. Outages aren't negligence. They're math.
Global SIM-enabled units (billions)
The fix isn't a better carrier. It's a SIM that doesn't depend on any single one. SmartSIM auto-fails over so your devices stay online even when the tower down the street can't keep up.
