Business Mobile Phone Contracts for UK Companies

AMVIA manages connectivity and security for 1,200+ UK businesses, and we treat mobile as part of your attack surface, not a side order. Most providers sell you airtime and walk away. We compare networks, run the contract, and enrol every device into mobile device management so a lost phone is a wiped phone, not a breach.

What is a business mobile contract?

A business mobile contract is a commercial airtime agreement between a company and a UK network — billed centrally, scoped to the number of users, and built around shared allowances rather than individual consumer plans. It bundles SIMs, optional handsets, data, and management into a single monthly cost with one renewal date.

Unlike a personal contract, a business agreement gives you pooled data, volume pricing, central billing, and the option to layer security and device controls on top. That last layer is where AMVIA differs from a network reseller.

• Pooled data across all lines instead of per-user caps
• Volume tariffs that improve as connection counts grow
• Central billing with one invoice and one account manager
• MDM-ready SIMs so every device can be secured and remote-wiped
• Mixed terms so renewal dates align across the business

What contract terms and tariffs are available?

Business mobile contracts run on 12, 24, or 36-month terms, and AMVIA mixes those terms across a single agreement so different teams renew on dates that suit them. Shorter terms protect flexibility for growing teams; longer terms enable lower monthly costs and stronger handset subsidies.

We also build SIM-only business mobile plans where you keep existing handsets, and 5G business mobile tariffs for field and hybrid teams that depend on fast mobile data. Each user can sit on a different tariff based on their role rather than a one-size plan.

How does AMVIA manage your mobile contracts?

AMVIA runs the full lifecycle: we audit your current contracts, compare every UK network, port your numbers, and then manage usage month to month. You get a single point of contact for billing, upgrades, and support rather than a network call centre queue.

1. Contract review — we audit your existing tariffs, usage, and costs to find waste and overage. 2. Network comparison — we compare tariffs across the major UK networks and negotiate rates, often saving 20–40% (typical UK 2026 range). 3. Migration and setup — we handle number porting, device configuration, and MDM enrolment with no disruption. 4. Ongoing management — monthly usage reviews, upgrade handling, and one contact for every query.

Handset upgrades are typically available 60 to 90 days before renewal, and we manage them across the whole fleet so new devices arrive configured and enrolled.

Why do UK SMEs need secured mobile contracts?

Mobiles hold email, files, and saved logins, which makes every handset a route into your business. A mislaid phone without device management is a data incident waiting to happen, so a business mobile contract should ship with security built in, not bolted on later.

The UK Government's Cyber Security Breaches Survey 2025 found that 43% of UK businesses experienced a breach in the past year, at an average disruptive-breach cost of £3,550, with roughly 19,000 UK businesses hit by ransomware. A managed mobile estate closes one of the easiest doors: lost and unmanaged devices. AMVIA enrols every SIM into Microsoft Intune mobile management and aligns it with your wider managed cybersecurity controls.

For teams that bring their own phones, our BYOD security approach separates work data from personal apps so you can wipe company access without touching an employee's photos. The National Cyber Security Centre recommends exactly this device-management baseline for mobile working (NCSC device security guidance).

How much do business mobile contracts cost?

Cost depends on user count, data needs, handset choice, and term length, so there is no single sticker price. Pooled data and volume tariffs make spend predictable, and AMVIA reviews usage quarterly to stop overage and trim unused lines before they cost you.

• SIM-only plans are the lowest monthly cost — no handset to fund.
• Airtime + handset spreads device cost across the term.
• Pooled data removes per-user overage charges across the fleet.
• Volume discounts grow with the number of connections.

We give you a fixed monthly figure per line and a single invoice, so finance can forecast mobile spend without surprises. Microsoft licence list prices for any bundled M365 security sit at £4.60 (Basic), £9.60 (Standard), and £16.90 (Premium) per user per month, ex VAT on annual terms (Microsoft 365 UK pricing).
