Business Mobile Phones and Device Management for UK Businesses

Business Mobile Management for UK SMEs

UK businesses collectively spend billions of pounds each year on mobile contracts, yet most have no centralised visibility of their SIM estate, no MDM policies in place, and no way to remotely wipe a device if it is lost or stolen. If your team uses company-owned phones — or their own devices to access work email and files — you need a structured approach to mobile management.

AMVIA manages business mobile fleets for organisations across the UK, from small teams of five to enterprises with hundreds of devices. Whether you need SIM-only contracts, full device procurement, mobile device management, or a BYOD policy, this guide explains what is involved and how to approach it.

Business Mobile Contracts vs Consumer Plans

Consumer SIM plans are designed for individuals. Business contracts offer materially different benefits that make them worth the switch for any organisation with three or more mobile users.

• Volume pricing: Networks offer significant discounts when you aggregate multiple lines under a single business account. These discounts are not available on consumer SIMs.
• Centralised billing: A single monthly invoice covers your entire mobile estate, simplifying finance and reducing administration.
• Data pooling: Business accounts allow data to be shared across SIMs, so heavy users can draw from a pooled allowance without incurring overage charges.
• Account management: You get a dedicated account manager and priority support, rather than dealing with a consumer call centre.
• MDM compatibility: Business SIMs and devices can be enrolled in mobile device management platforms from day one, enabling remote control and security policies.

Which Network Is Best for Business?

The right network depends on where your team works. O2 and EE tend to lead on rural UK coverage, while Vodafone has strong international roaming agreements. Three offers the best value SIM-only data plans for urban-based teams. AMVIA is network-agnostic and will recommend the best option based on your usage patterns and postcode-level coverage analysis — or split your fleet across networks where coverage requirements vary by role.

Mobile Device Management (MDM): What It Is and Why You Need It

Mobile Device Management is software that lets your IT team — or your managed IT provider — remotely control every device enrolled in your organisation. The most widely deployed MDM platform for UK businesses is Microsoft Intune, which is included with Microsoft 365 Business Premium licences.

What MDM Can Do

• Enforce PIN, fingerprint, or face ID lockscreens on all devices
• Require device encryption so data cannot be accessed if a handset is lost
• Push apps and configurations to devices without user involvement
• Restrict which apps can be installed from the app store
• Separate work and personal data into distinct containers on BYOD devices
• Remotely wipe a device — or just the corporate data — if it is reported lost or stolen

MDM vs MAM: What Is the Difference?

Mobile Application Management (MAM) is a subset of MDM. Where MDM manages the entire device, MAM manages only the apps on the device. MAM is commonly used for BYOD scenarios where employees would not consent to full device management. For example, with MAM you can control the Microsoft Outlook and Teams apps on a personal iPhone without having any visibility of personal photos, messages, or other data.

BYOD: Managing Employee-Owned Devices

Many UK SMEs allow staff to use personal phones for work purposes — accessing work email, Teams messages, or company files on their own device. This is common practice, but it carries significant risk if not properly managed.

Without a BYOD policy, an employee leaving the company could retain access to work email on their personal phone indefinitely. A personal device infected with malware could be used to access corporate files. If a personal phone is lost, there is no way to remove the corporate data from it.

What a BYOD Policy Should Cover

• Which devices and operating systems are permitted (minimum iOS or Android version)
• Which MDM or MAM platform will be used to manage corporate data on personal devices
• What the organisation can and cannot see on an employee's personal device
• What happens to corporate data on the device when an employee leaves
• Whether the company contributes to the employee's phone bill

AMVIA will draft a BYOD policy for your organisation, deploy the appropriate MDM or MAM configuration, and train your team on what it means for them.

Cost Breakdown: What Does Business Mobile Management Cost?

The cost of business mobile services depends on several factors: the number of devices, the networks chosen, whether devices are supplied or SIM-only, and whether MDM management is included.

• SIM-only business contracts: Typically £8–£20 per SIM per month, depending on data allowance and network. Volume discounts apply from around 10 SIMs.
• Full device contracts (handset included): From around £20–£45 per device per month over 24 or 36 months, depending on the handset model.
• MDM management (Intune): Included in Microsoft 365 Business Premium (£18.60/user/month). AMVIA's management and support layer is charged per device per month.
• AMVIA managed mobile service: All-inclusive mobile management — contract sourcing, MDM, SIM management, device support — from approximately £15 per device per month.

How to Choose a Business Mobile Provider

When selecting a business mobile provider or managed service, look for the following:

• Network agnosticism: A provider tied to one network cannot always give you the best deal. AMVIA works across all major UK networks.
• MDM integration: Your mobile provider should be able to enrol devices in MDM on your behalf and manage the configuration.
• Clear SLA: What happens when a device is lost, broken, or needs replacing? A managed provider should have a defined process.
• Consolidated billing: Look for a single monthly invoice that covers all networks, devices, and management — not separate bills from each network.
• UK-based support: When staff have a problem with their work phone, they need fast, UK-based support — not an overseas call centre.

Business Mobiles for Different Business Sizes

Small businesses (10–25 staff): SIM-only contracts with basic MDM through Microsoft Intune are usually sufficient. Focus on getting all devices enrolled and a remote wipe policy in place.

Mid-market businesses (25–100 staff): At this scale, a managed mobile service makes sense. Consolidated billing, data pooling, and a formal BYOD policy will deliver measurable cost savings and security improvements.

Larger SMEs (100–500 staff): A dedicated mobile fleet management programme with full MDM, regular audits, and a device refresh cycle will be required. AMVIA provides this as part of a broader managed IT engagement.
