When the line fails, the SIM takes over.
The router carries two routes at once. Traffic uses the fibre; if that line drops, the 4G/5G route takes over automatically and the portal raises the alert, so phones, card machines and cloud apps carry on.
The backup SIM roams across the main UK networks, so it joins whichever signal is strongest at your address.
Pick the muscle your site needs.
Assure X LTE6
The dependable workhorse
Cat-6 LTE up to 300Mbps, WiFi 6 AX1800, 4× gigabit + 1× 2.5G Ethernet. Rated −40°C to 70°C with a ~200,000-hour MTBF — built to sit in a comms cabinet for years and just work. Right for most shops, offices and practices.
Assure X 5G
The performance model
Full 5G (SA/NSA) with LTE Cat-20 fallback — up to 2Gbps — 4×4 MIMO, WiFi 6, the same industrial passive-cooled build. For sites where the backup line carries the whole business at speed: busy hospitality, multi-till retail, larger offices.
Automatic cutover
Watches your fixed line and switches the moment it fails — then back when service returns. No one touches anything.
Multi-network SIMs
Roams EE, Vodafone, O2 and Three — the strongest signal at your postcode wins, not whichever network you signed with.
Zero-touch managed
Firmware, diagnostics and config handled remotely by our UK engineers. You get uptime; we do the tending.
When the line drops, nothing else does.
- Multi-network SIM roams to the strongest signal
- Switch-over is automatic and monitored
- Phones, card machines and cloud apps stay live
The numbers that matter, side by side.

Which model fits depends on your line speed, site size and what has to survive an outage — we specify it as part of the failover design, not as a box off a shelf.
Assure X, answered.
Does Assure X switch over automatically?
Yes. The router monitors your fixed line continuously and cuts over to 4G/5G the moment it fails, then returns to the fixed line when service is restored. No manual intervention is needed.
Which networks does the failover use?
We pair Assure X with multi-network SIMs that roam across EE, Vodafone, O2 and Three, connecting to the strongest signal at your site rather than a single network.
Will my card machines and phones keep working in an outage?
That is the point of the design: payments, VoIP calls and cloud apps continue over the mobile connection. We size the model — LTE6 or 5G — to the load your site needs to carry.
Do I need to manage the router?
No. Every Assure X we supply is remotely monitored and managed by Telexico's UK engineers, including firmware and configuration.
Downtime is a choice. Choose against it.
