Stay online when yourmain line cuts.
Automatic 4G/5G failover keeps phones, card machines and cloud apps live when broadband goes down.
4G/5G Failover Internet pain points we hear every week.
If any of these feel familiar, it's not a tech problem — it's a provider problem.
"Our last outage cost us £800."
Three hours offline. No card payments, no VoIP, no cloud booking system. Customers walked. Failover would have saved every penny of it.
"Engineer said the fix would take 24 hours."
Openreach prioritises residential restorations. Your business takes a day to come back. Without failover, that's a day's revenue lost.
"We don't even know when broadband cuts."
Found out from a customer call. Embarrassing and expensive. Proper failover tells your team the second a line drops.
"Multi-site outages happen randomly."
Each location depends on its own line. One cable strike near one site = one site dark. Per-site failover insures every premises individually.
"5G coverage in our area is solid but unused."
EE and Vodafone hit 200+ Mbps in most West Midlands towns. Sitting there waiting. Failover puts it to work as your backup.
"We tried a USB 4G stick. Useless."
Consumer dongles, one device at a time, no routing. Proper failover routers seamlessly take over the WHOLE network within 30 seconds.
4G/5G Failover Internet done properly.
What you get when Telexico builds it.
Automatic switchover under 30 seconds
Failover router detects line loss, switches the entire network to 4G/5G without manual intervention. Calls and payments keep flowing.
Multi-carrier SIM cards included
EE + Vodafone + Three. If one network is congested or down, the router picks the best. No single-carrier risk.
Bandwidth controls during failover
Prioritise card machines and VoIP, deprioritise streaming during failover so the limited 4G bandwidth goes where it matters.
Alerts when primary line is down
SMS + email to your team the moment broadband cuts and 4G kicks in. So you know — and you fix it — before customers notice.
Multi-site failover dashboards

Plug-and-play install in under 1 hour
We supply pre-configured routers, you (or we) plug them into your existing setup. Most installs are under 60 minutes.
Built for businesses that need reliability, speed and control.
The maths most businesses haven't done.
Most UK business broadband outages last between 30 minutes and 3 hours. The real cost isn't the £30 line rental — it's lost trade, idle staff, missed calls, frustrated customers and the operational chaos of being half-functional during peak hours. Here's the rough calculation we walk through with every customer.
Restaurant or takeaway
Friday lunch service offline for 90 minutes — card machine down, online orders failing, phone bookings missing. Typical UK SMB: £400-£1,200 lost trade plus reputation damage with regulars who tried to book.
Dental or healthcare practice
Card machines down, patient management system offline, appointment booking broken. Half-day outage means rebookings, staff sent home, plus emergency-cover patients reaching voicemail and going elsewhere. £600-£1,500 typical loss.
Retail with 3+ tills
Card payments offline mid-Saturday rush. Cash-only for 2 hours. 30-40% conversion drop on non-cash sales. Estimated £200-£800 lost per till per hour during peak.
Office with hosted services
Cloud apps, VoIP, Teams, CRM all dependent on internet. 20 staff sat idle waiting for restoration. £20-£40 per staff member per hour in wage cost alone, plus the work that doesn't get done.
Garage or workshop
Booking phone offline, MOT system down, parts ordering halted, card payments failing. Average garage loses £150-£400 per hour of downtime — and customers don't come back if they couldn't book.
Construction or trades office
Project management software offline, calls missed from site teams needing materials, supplier orders blocked. Less direct revenue loss but project slippage that compounds. £200-£500 in coordination friction.
Multi-WAN architecture so the business never goes offline.
Assure X is the Telexico-branded resilient connectivity stack — multi-WAN routing across diverse circuits that automatically maintains business continuity. Built around managed business-grade routers (MikroTik, Draytek, Cisco) with monitoring, alerting and failover testing.
4G/5G failover — Vodafone & EE
Dual-carrier SIM in the failover router means even one mobile network outage doesn't kill the backup. EE for West Midlands coverage, Vodafone for nationwide redundancy. Automatic selection of strongest signal.
Starlink as failover or primary
For locations with poor mobile signal or where Starlink IS the right primary connectivity — managed Starlink integration with multi-WAN routing. Especially relevant for rural, semi-rural or fringe industrial sites.
Diverse-circuit failover
For larger sites: two physical broadband circuits from different carriers (e.g. Openreach FTTP + CityFibre full fibre). Genuine diversity — when one provider has a problem, the other usually doesn't.
30-second automatic switchover
Managed dual-WAN router monitors primary connectivity continuously. Detects loss within 10-30 seconds. Automatically switches all traffic (data, voice, VPN) to the backup path. Switches back when primary restored.
We know about it before you do
Network monitoring alerts our team the moment your primary line drops — we're often investigating before you've noticed. SMS/email alert to your nominated contacts.
Monthly failover testing
Quarterly failover tests scheduled out-of-hours to verify the backup path actually works. Many businesses think they have failover until the day they need it. We make sure yours actually fires.
The technical depth behind Assure X.
Failover sounds simple — "just plug in a 4G dongle." The reality of business-grade continuity is more technical: VoIP needs QoS to stay clear during failover, VPNs need persistent IP behaviour, card machines need PCI-segregated traffic. Here's the architecture.
Resilient mobile failover across every UK network.
A single-carrier 4G failover has a hidden weakness — if EE has a regional outage, your 'failover' is offline at exactly the same moment as your main broadband would be (the same storm, the same civil-engineering damage, the same exchange issue often hits multiple networks). Multi-carrier failover deploys dual or quad-SIM routers covering EE, Vodafone, O2 and Three so a single network outage doesn't kill resilience.
Dual-SIM EE + Vodafone
Standard Telexico failover specification — primary EE (best West Midlands coverage), secondary Vodafone (best UK-wide redundancy). Router auto-selects the strongest signal in real time. Failure of either carrier still leaves the business online.
Quad-SIM coverage
For sites with mission-critical uptime needs (healthcare, finance, multi-site retail), we deploy quad-SIM routers covering EE, Vodafone, O2 and Three. Bonded throughput, intelligent network selection, single network outage barely registers.
Regional carrier optimisation
Coverage varies hugely by postcode. West Midlands urban: all 4 carriers strong. Rural Shropshire: EE and Vodafone usually best. Industrial estates: often O2 or Three are surprisingly strong. We survey signal strength on-site before specifying which carriers your failover uses.
External antennas where signal needs help
If your building has thick walls or shielding (warehouses, basements, listed buildings), the failover router goes outside the box — external roof-mounted antennas connected via cable. Often turns a 'no signal' postcode into a reliable failover site.
Live signal monitoring
Every Telexico-deployed failover router reports signal strength continuously. We see degradation before it affects your business. Quarterly signal-quality reports help identify if a network swap is warranted (carriers add/remove cells, coverage changes).
Roaming options for cross-border sites
For sites near borders (Welsh, Scottish, Irish proximity) or businesses with mobile assets crossing networks, roaming-aware failover SIMs prevent dead zones at carrier handover boundaries.
Who needs failover internet — and why.
Telexico deploys 4G/5G failover and resilient connectivity across every UK commercial sector. The specific use case differs — a restaurant needs card-payment uptime, a warehouse needs WMS connectivity, a dental practice needs patient management continuity — but every business with internet-dependent operations benefits from automatic backup connectivity.

Frequently asked questions
What 4G/5G speeds can I expect on failover?
Most UK business addresses hit 50-200 Mbps on 4G, 100-500 Mbps on 5G. Enough to keep VoIP, card machines, and basic cloud apps running normally. Heavy streaming and big uploads slow down — that's a feature, not a bug.
Will calls drop during the switchover?
Sometimes a brief blip (1-5 seconds) on the actual moment of switching. The router holds existing TCP connections where possible. Most users don't notice.
Do I need a SIM contract separately?
No — we include the multi-network SIM in the failover package. One bill, one provider. We work with wholesale rates so the SIM is more cost-effective than a retail BT/EE business plan, and you don't need a separate contract.
What if 4G coverage is poor at my premises?
We check signal during the survey. If 4G is weak, we can fit external 4G antennae for better signal, or use the 5G band where available. We don't sell failover where it can't physically work.
Can I use failover without your broadband?
Yes — we can install failover alongside any existing broadband (BT, Virgin, TalkTalk, etc.). Most affordable to bundle with our broadband but not required.
How long should I expect my main broadband to be down before failover takes over?
Automatic — the router detects loss within 10-30 seconds and switches. No manual intervention.
Is there a data cap on the 4G/5G plan?
Standard plan: 100GB/month — plenty for a normal failover scenario (one or two outages monthly). Heavy-use plans up to unlimited available.
What is failover internet?
Failover internet is a business continuity solution that automatically switches your network onto a backup internet connection when your primary broadband or leased line fails. This prevents downtime affecting VoIP phones, cloud software, EPOS systems, CCTV and payment terminals. It's the difference between a 30-second blip and a 3-hour outage.
Is 4G or 5G better for business failover?
Depends on coverage. 4G has wider UK coverage and is the practical choice for most industrial estates, rural sites and smaller towns. 5G delivers significantly higher speeds where coverage exists and is the right choice for bandwidth-heavy environments. We check signal strength at your postcode before specifying — sometimes both 4G and 5G as a dual-SIM solution.
What is SD-WAN and do I need it?
SD-WAN (Software-Defined Wide Area Network) intelligently routes traffic across multiple connectivity paths — fibre, leased lines, Starlink, 4G/5G — based on real-time performance. For single-site small businesses, a dual-WAN router is usually enough. For multi-site organisations or businesses with mission-critical uptime needs, SD-WAN provides centralised intelligent routing across the entire WAN.
Can failover work alongside my leased line?
Yes — leased lines should always include failover. Even a 99.99% SLA leased line goes down occasionally (carrier faults, civil engineering damage). 4G/5G failover preserves business operation through these events. We deploy leased-line + 4G/5G failover combinations as standard for businesses where uptime matters.
Do you test failover before something breaks?
Yes — and this matters more than people realise. Many businesses technically have backup connectivity but discover during an actual outage that it was never configured properly or tested under real load. Telexico performs scheduled failover testing quarterly so the backup path actually works when needed, not just in theory.
