Comparing VoIP, Broadband, Mobile & IoT for UK SMEs
For many SMEs, choosing the right telecoms setup isn’t just about speed or cost—it’s about ensuring every part of your business stays connected and competitive. But with so many services on offer—from VoIP phone systems to business mobile, broadband and IoT SIM cards—where do you begin?
In this guide, we compare the four main connectivity services provided by Fidelis Plus, helping you understand their benefits, differences, and ideal use cases. Whether you’re looking to simplify providers, cut costs, or improve performance, this overview will give you clarity.
Understanding Your Options: Four Pillars of Business Connectivity
1. Business VoIP Systems
VoIP (Voice over Internet Protocol) is the modern replacement for traditional landlines. Instead of running through the PSTN (which is being phased out by 2025), calls are made over the internet. For businesses, this means:
Lower call costs (especially international)
Flexibility for remote and hybrid teams
Advanced features like call forwarding, auto-attendants and analytics
At Fidelis Plus, our Business VoIP Systems are designed specifically for SMEs needing a dependable, scalable solution.
2. Business Broadband
Reliable internet is non-negotiable. But not all broadband is equal. Business-grade broadband typically offers:
Guaranteed speeds and SLAs
Priority support and static IPs
More robust routers and uptime guarantees
We provide Business Broadband options tailored to your usage—whether you’re a team of 3 or 30, in-office or fully remote.
3. Business Mobile
With more work happening on the go, company mobiles need more than just data. Our Business Mobile plans offer:
Flexible SIM-only deals or devices included
Pooled data and usage monitoring
Access to multiple UK networks for coverage
Perfect for field-based staff, engineers, or directors needing mobile continuity.
4. IoT SIM Cards
For connected devices—whether that’s smart meters, GPS trackers or payment terminals—IoT SIMs are essential. Our IoT SIM Cards support:
Global roaming for cross-border connectivity
Multi-network resilience in the UK
Remote management via SIM control portals
Ideal for industries relying on automation, logistics or telemetry.
Comparing the Four: Costs, Features & Use Cases
Service | Typical Use | Key Benefits | Considerations |
|---|---|---|---|
VoIP | Replacing landlines, call centres, hybrid working | Lower call costs, remote-friendly, feature-rich | Needs stable broadband |
Broadband | Internet access for offices and remote setups | Reliable speeds, SLAs, static IPs | Varies by location |
Mobile | Field staff, directors, mobile continuity | Network choice, pooled data, flexibility | Need device policies |
IoT SIMs | Connected devices, M2M comms, automation | Resilient coverage, global reach | Requires device compatibility |
Which Solution Fits Your Business?
It’s not about choosing one—it’s about choosing the right mix.
VoIP: Best for Call-Heavy Teams
Law firms, recruitment agencies, and call centres often rely on VoIP for their main customer communications. With features like call queuing and detailed reporting, VoIP supports performance-driven teams.
Broadband: Best for Office-Based SMEs
If your team is mostly in one place, stable business broadband ensures seamless access to cloud systems, email and video calls. Add in remote monitoring and SLAs, and it’s a key part of uptime.
Mobile: Best for Staff on the Move
From delivery firms to sales reps, business mobile keeps your people connected and accountable. With usage controls and pooled data, it’s a smart, scalable option.
IoT SIMs: Best for Device-Led Workflows
Whether you run vending machines, smart CCTV or vehicle tracking, IoT SIM Cards offer the network reach and control to keep your devices online and data flowing.
Why Bundle with One Provider?
Many SMEs start with multiple suppliers—one for internet, another for mobiles, a third for phones. But this quickly becomes a headache:
Disjointed support
Confusing billing
Poor integration
At Fidelis Plus, we bring everything under one roof. You get unified support, flexible billing, and telecoms that simply work—whether that’s VoIP, broadband, mobile or IoT.
