5G Business Mobile Plans for UK Companies

This page sits inside AMVIA's wider business mobile service, so you can run 5G handsets, SIM-only business mobile plans and device security under a single accountable contract instead of juggling a network reseller and an IT provider.

Who benefits most from 5G business mobile?

5G earns its place where staff depend on mobile data for heavy, time-sensitive work — large file transfers, cloud apps and video calls — in areas with good coverage. For email and light browsing, a 4G plan is often enough. AMVIA advises per role, based on real usage, not a blanket upgrade.

• Field and mobile workers — engineers, sales reps, consultants and delivery teams get faster access to cloud CRM, route planning, reporting and file sharing that drags on congested 4G.
• Remote and hybrid staff — a 5G SIM in a mobile router delivers broadband-equivalent speeds where fixed lines are unreliable or absent.
• Video conferencing on the move — 5G's higher speed and lower latency make Teams and Zoom calls far steadier on mobile data than 4G.
• Construction and manufacturing sites — temporary or fixed-line-free locations can connect staff, IoT devices and site management apps over 5G mobile routers, with backup connectivity where uptime matters.

What's included in AMVIA's 5G business mobile service?

AMVIA runs the whole lifecycle: we check coverage, choose the right network and plan per role, pre-configure devices with your apps and security policies, then manage billing, upgrades and usage. You get one provider accountable for the connection and the security on it, not a hand-off between two suppliers.

• Coverage check — we verify 5G availability at each of your sites and recommend the strongest network for your area.
• Plan selection — we match data usage, call patterns and budget to the most cost-effective plans across all UK networks.
• Device and SIM setup — handsets arrive pre-configured with business apps, email and mobile device management policies already applied.
• Ongoing management — we handle upgrades, billing queries and usage monitoring so you never overpay or run short on data.

How much does 5G business mobile cost in the UK?

Costs depend on data allowance, contract length and how many SIMs you take. As a guide, a typical entry-level 5G business plan with a 50GB allowance runs in the low-to-mid teens per SIM each month, before device costs. AMVIA benchmarks live tariffs across networks so you only pay for what each role actually uses.

Prices exclude VAT and handset costs. We size allowances to measured usage rather than selling every user the largest bundle — pooled data across a fleet usually beats per-SIM upgrades.

5G business mobile vs a fixed leased line — which do you need?

5G is excellent mobile connectivity; it is not a replacement for a fixed office line. A leased line gives dedicated, symmetric, uncontended bandwidth with a guaranteed SLA. 5G has no equivalent SLA and is subject to coverage and contention. Use 5G for mobile and resilient backup, a leased line for the primary office.

Why do UK businesses need secure 5G business mobile?

Mobile devices are now a primary target, not an afterthought. With 43% of UK businesses reporting a cyber breach or attack in the last 12 months (DSIT Cyber Security Breaches Survey 2025), an unmanaged 5G handset holding email and cloud data is a real exposure. AMVIA treats every SIM as a managed, secured endpoint.

Each device we deploy carries mobile security controls — enrolment, encryption, conditional access and remote wipe — applied through Microsoft Intune before the handset reaches the user. The NCSC's mobile device guidance sets the baseline we build to, so a lost phone is an inconvenience, not a breach.

Which UK network has the best 5G coverage for business?

There is no single best network — it depends on where your people work. EE has the widest 5G coverage nationally; Three offers the fastest speeds where available; Vodafone and O2 hold strong urban coverage. AMVIA checks coverage at every key location, drawing on Ofcom's reporting, before recommending a network or a multi-network mix.

• EE — widest national 5G footprint, strong for distributed teams.
• Three — fastest 5G speeds in covered areas.
• Vodafone / O2 — robust city and town-centre coverage.

Independent coverage data is published in Ofcom's Connected Nations reports, which we use alongside on-site checks to avoid coverage surprises.
