4G failover for UK business broadband.
Affordable, fast-to-deploy cellular failover for UK businesses — automatic switching, business-grade SIM, integration with the managed router. Keeps card payments, VoIP and cloud apps running when the primary line goes down.
What we hear every week.
The frustrations behind why businesses search for 4g failover for business in the first place. If any of these feel familiar, the fix is straightforward.
Affordable resilience for SMEs
Dual leased lines is too expensive for most SMEs. 4G failover delivers most of the operational benefit at a fraction of the cost.
Fast to deploy — live in days
Unlike second fibre lines (60-120 days install), 4G failover can be live in a week. Useful where business pressure is immediate.
Most UK business addresses have decent 4G coverage
Coverage varies but most UK commercial addresses have usable 4G from at least one major network. We assess before recommending.
VoIP and card payments need to keep working
The two highest-impact business losses during a broadband outage. 4G failover keeps both running.
4G failover, deployed and managed properly
Telexico deploys 4G failover as part of a managed dual-WAN router setup. We assess cellular coverage at your address (which networks deliver strong signal — EE, Vodafone, Three, O2 — varies postcode by postcode), supply business-grade SIM(s) with appropriate data allowances, configure automatic failover policy on the managed router, and integrate with hosted VoIP so calls keep working. Where the primary fibre is FTTP or leased line, 4G failover provides immediate operational continuity for typical UK SME outage events.
The Telexico approach to 4g failover for business.
Six things our customers consistently tell us matter.
Sub-second failover
Managed dual-WAN router switches traffic to 4G when primary fails — automatic, no manual intervention.
Right network for your address
We test cellular coverage from multiple networks and pick the one that performs best at your specific site.
Card payments stay live
EPOS and card terminals keep working through outages — critical for retail and hospitality.
VoIP continuity
Voice traffic routes over 4G during outages — calls may briefly drop but reconnect on the backup.
Affordable
Typical monthly cost £25-75 plus a small one-off — meaningfully cheaper than dual leased lines or Starlink.
Telexico monitoring and support
We see failover events, alert you, and work on restoring primary. UK engineers, UK support.
Built for typical UK business outage events
Most UK business broadband outages are short and localised — Openreach incident on a specific exchange, civils work cutting a cable, equipment failure at the carrier. 4G failover catches the majority of these because cellular networks are independent of fixed-line infrastructure. For events that affect both cellular and fixed-line (regional infrastructure incidents, major weather events), Starlink is the more diverse backup. For most SMEs, 4G is the right proportionate response.
How it works for businesses like yours.
Three real-world setups we deliver across the UK.
Retail with card-payment uptime
Independent retailers, small chains — 4G keeps EPOS and card terminals running through outages without breaking the bank.
Hospitality and food service
Restaurants, pubs, takeaways — bookings, OpenTable, card payments, delivery-app integration all stay live.
Professional services with VoIP continuity
Solicitors, accountants, consultancies — voice traffic stays on the backup when the primary fibre drops.
Why UK businesses choose Telexico for 4G failover
We design and deploy 4G failover that's actually integrated, actually tested, actually monitored. Wolverhampton-headquartered, UK engineers, UK support. One Telexico provider for the failover plus the primary fibre plus phones plus WiFi.

UK-based provider
Wolverhampton-headquartered. Engineers cover the West Midlands daily; UK-wide install via our partner network. Real UK engineer support, UK data residency, UK contractual relationship — not US-routed SaaS.
Real engineer support
When you call Telexico, you reach someone who can actually fix things. Response SLA backed by real engineering capacity rather than call-centre headcount. Named account manager for ongoing customers.
Free infrastructure review
Every engagement starts with a no-obligation audit of your current setup. Honest recommendation — sometimes that's "stay with your current provider after negotiation." We'd rather be honest than oversell.
Transparent pricing
What you sign for is what you pay — including renewal. No teaser pricing that jumps 30-100% at year two. No mid-contract CPI shock. Predictable multi-year cost from day one.

Frequently asked questions
Will 4G failover work at my address?
Most UK commercial addresses have usable 4G from at least one major UK network. We test coverage from EE, Vodafone, Three and O2 during the survey and pick the network that delivers strongest signal. Where coverage is poor across all networks, we recommend Starlink as an alternative.
How much data does 4G failover use?
Depends on usage — typical office use during failover (VoIP, browsing, email, light cloud apps) is 5-15GB per day. We supply business SIM packages with appropriate data allowances; some are uncapped. Sized to your operational pattern.
What speeds can I expect on 4G failover?
Typical UK 4G delivers 20-80Mbps down, 5-20Mbps up at typical business addresses with good coverage. Enough for normal business operations during a primary outage. Not the same as fibre — but enough to keep you running until primary returns.
What about 5G — is that better than 4G failover?
Where 5G is available, yes — significantly higher speeds and lower latency. Where 5G isn't available yet (most UK addresses outside major cities), 4G is the right answer. We deploy 5G where coverage supports it.
Does 4G failover work with hosted VoIP?
Yes — VoIP traffic routes over 4G during failover with reasonable quality (latency 30-60ms typical). Calls may briefly interrupt during the failover transition; subsequent calls work normally on 4G.
How much does 4G failover cost?
Typical monthly £25-75 depending on data allowance and network. One-off install £100-200 covers the SIM, configuration and integration with the managed router. Often less than a single significant outage would cost in lost revenue.
Can I have 4G as primary and FTTP as backup?
Yes — that configuration works in reverse where it makes sense (typically rural locations without good fibre, or where 4G coverage is genuinely excellent). We design around the operational priorities.
