Digital Signage Connectivity
Connectivity that keeps your screens live at any scale. Provision SIMs in minutes, manage connectivity per client, and resolve device issues remotely.
Digital signage companies across the UK use SIMSY to eliminate the delays, inflexible tariffs, and blind spots that come with legacy providers.
Managing connectivity at scale is harder than it should be
Most digital signage operators are working around the same set of problems with traditional providers.
Slow SIM Provisioning
Getting new SIMs live takes days through traditional providers. Every delay pushes back an install, frustrates a client, and risks your relationship before a single screen has loaded. A three-day provisioning window on ten concurrent sites is a month of friction you did not budget for.
Tariffs That Do Not Flex
Fixed data plans force you to over-provision or under-serve. You cannot build per-client packages or adjust as deployments grow. The result is margin erosion on both sides: paying for data clients do not use, or scrambling when they suddenly need more.
No Visibility on What Is Happening
Without real-time usage data per SIM and per client, billing is guesswork and fault diagnosis is reactive. No proactive alerts means no warning on power outages, no notification on connectivity drops, and no way to demonstrate uptime to clients.
Every Problem Becomes a Site Visit
When a screen goes dark you cannot easily tell whether the fault is the SIM, the router, the network, or the display itself. Without remote access to the full device stack, every undiagnosed issue becomes an expensive engineer callout.
Purpose-built for signage operators
Every feature designed to give you control over your connectivity estate, from provisioning to fault resolution.
Instant SIM Provisioning
Activate SIMs in minutes, not days. New sites go live faster and installs are never held up waiting on an activation queue. For operators running concurrent deployments, that speed compounds into a real competitive advantage.
Per-Client Tariff Control
Build bespoke data packages per customer and adjust usage limits in real-time as deployments evolve. Full billing visibility per SIM, per site, per client, so the numbers always reconcile cleanly.
Full Remote Access
SIMSY gives you the whole stack, including the screen itself. When something goes wrong, your team can log in remotely, identify whether the fault is connectivity, hardware, or software, and resolve it without dispatching anyone.
Multi-Network SIM
One SIM, four networks. SIMSY automatically connects each device to the strongest available UK signal — EE, Vodafone, O2 or Three. No single-carrier black spots, no manual network selection.
Proactive Alerts
The moment a SIM goes offline, power drops, or a data threshold is reached, you know about it. Alerts come immediately, giving your team time to diagnose and respond before it becomes a complaint.
Secure Multi-APN
Run completely separate logical networks on a single SIM. Management traffic stays isolated. Customer-facing traffic, including card payment environments, runs in complete isolation. All on one SIM with no additional hardware.
Full API Access — Automate SIM management, trigger provisioning, pull usage data, and integrate directly into your own platform or NOC.
Live in three steps
From order to fully managed connectivity across your signage estate.
Order and activate your SIMs
SIMs arrive pre-configured and ready to activate. Activation takes minutes through the SIMSY dashboard or API. No waiting on a carrier provisioning queue. If you want to move an existing estate across, we handle the migration process with you.
Set up your client structure
Organise SIMs and devices by client, site, or however your business is structured. Set per-client data tariffs, configure alert thresholds, and establish your Multi-APN groups. Everything is visible in one dashboard and fully accessible via the API.
Monitor, manage and resolve from anywhere
Real-time visibility of every SIM in your estate. Offline alerts fire the instant connectivity drops. Remote access lets your team reach the full device stack without visiting site. Usage data flows per SIM, per client, in real-time.

Real-World Deployment: UK Signage Operator
A large-scale digital signage operator. Names withheld, outcomes are real.
The Situation
A UK digital signage operator deploying connected screens across retail, transport, and public sector environments was struggling with scale. New site activations were regularly delayed by slow SIM provisioning. When connectivity issues occurred, their operations team had no remote visibility into the device stack. Every unresolved issue meant a site visit, cost, delay, and another conversation with a client asking why their screens were down.
The Deployment
The operator moved their connectivity estate to SIMSY, gaining instant SIM provisioning across all UK locations. Using SIMSY's remote access tools, their operations team could now reach both the router and the display layer remotely. Proactive alerts notified them the moment a SIM went offline. Per-client tariff control meant bespoke data packages adjusted in real-time. They also deployed Multi-APN configuration, isolating management traffic from customer-facing networks.
The Outcome
Provisioning time reduced from days to minutes. The number of reactive site visits dropped significantly and remote resolution became the operational norm. Clients gained confidence. Real-time visibility and faster fault resolution meant fewer escalations and stronger account relationships.
“Provisioning time dropped from days to minutes. The team now resolves most issues without leaving the office.”

One SIM. Four networks.
Our multi-network SIM automatically selects the strongest available signal at every location. Urban retail, rural transport hubs, temporary event installations. SIMSY keeps them connected.
Common questions
Everything you need to know about SIMSY for digital signage.
It depends on the size of the estate, but most operators are fully migrated within a few weeks. We work with you on the plan so devices are swapped over in batches with no connectivity gaps. Many operators start with new installs and migrate existing devices over time.
Yes. Full API access is included as standard. You can automate SIM provisioning, pull real-time usage data, trigger alerts, and manage tariffs programmatically. If your operations team has an existing dashboard, SIMSY data can flow directly into it.
The SIM automatically registers on one of the other three UK networks. The failover is handled at the SIM level with no manual intervention required. A single-network outage should not take any of your screens offline.
SIMSY is priced per SIM per month and is competitive with single-network providers once you factor in the multi-network coverage, remote access, and management platform included. There are no hidden costs for API access, alerts, or dashboard features.
Yes, that is one of the core features. Each client or group of SIMs can have its own tariff, independent of every other client. You can set data caps, configure alerts when thresholds are reached, and adjust allowances in real-time.
No. The dashboard is built for operations teams, not developers. Managing SIMs, setting tariffs, and monitoring your estate is straightforward through the web interface. The API is there if you have a development team that wants to build deeper integrations, but it is not required.
