What’s Slowing Down Your IoT Right Now?

  • Locked SIMs mean dead zones.
    One carrier can’t cover everything. Your devices go offline in rural or high-density areas, , creating frustrating blind spots in your operation.
  • Your SIM Sticks to a Dead Network
    Signal drops. No failover. Your device is offline and your customers lose trust.
  • Traffic gets routed across the globe.
    Data shouldn’t loop through Europe just to reach Chicago. Long routes mean slow performance and compliance headaches.
  • You’re juggling multiple contracts, dashboards, and APIs.
    Too many vendors, too much complexity, no unified control. Managing a patchwork of carriers is an operational headache that slows you down.

What Our Customers Are Saying

Collaborating with floLIVE through an API-first approach makes it easier to deliver an embedded and optimised solution. For example, the floLIVE dashboard and insights could be useful to us or our customers
Mohammed Ansari
Senior director of Business Development, Qualcomm Technologies
floLIVE solved our cross-border connectivity issues and finally gave us a pricing model that makes sense — only charging for active endpoints and consumed data, not idle SIMs.
Stefano Iannini
CEO USA & Canada, The Aroma Trace
floLIVE’s ability to provide a single SKU that behaves the same everywhere is invaluable. Getting the SIMs directly to our factory and knowing they will work consistently worldwide simplifies our operations significantly.

Frequently Asked Questions
What’s the difference between roaming SIMs and floLIVE’s multi-network SIMs?

Roaming SIMs connect to foreign networks through a single home operator. That often leads to high latency, limited failover, and compliance issues — especially at scale.
floLIVE’s multi-network SIMs are different. They provide access to multiple local networks (like Verizon, AT&T, and T-Mobile in the U.S.) — with local breakout, intelligent failover, and full regulatory compliance built in. Your data stays local. Your devices stay fast. Your team stays in control.

Do I need separate SIMs for each carrier or country?

No. With floLIVE, you get access to Verizon, AT&T, and T-Mobile in the U.S., and 600+ networks globally — all with one SIM or eSIM profile. No swapping, no operator lock-in.

How does failover work with floLIVE?

Our intelligent SIM detects connection issues in real-time and automatically switches to the next best available network — no manual resets, no downtime.

Do you support eSIM (eUICC)?

Yes. floLIVE fully supports eUICC. Your first profile can be multi-network, saving cost and setup time. You can manage profiles through our unified platform or APIs.

What kind of support do you offer?

We provide 24/7/365 global support with real humans who understand IoT, connectivity, and deployment at scale. You’ll always have someone who can help, fast.

Do I get real-time visibility into my devices and network?

Yes — floLIVE gives you full, real-time visibility into your devices, SIMs, and network activity. From activation and usage to diagnostics and alerts, everything is available through a single dashboard or API.

Can I try before I commit?

Yes! We offer a free starter kit with full access to our platform, networks, and APIs — so you can test performance, failover, and coverage in real-world conditions.
