If you’re looking to reduce overheads, business SIM card costs are one of the easiest places to start.

Unlike larger infrastructure changes, SIM costs are often hidden in plain sight. Most businesses set them up once, then rarely review them again, but they are one of the simplest areas to optimise. Assessing your usage and making small adjustments can lead to ongoing monthly savings without disrupting how your team works.

What is the best way to manage and reduce multiple business SIM cards?

1. Review Actual Call and Data Usage

The first step is understanding what you’re actually paying for versus what you’re using.

Most businesses find that with business SIM cards, data and call allowances are significantly higher than real-world usage.

This leads to:

• Paying for unused data bundles
• Over-specced contracts per employee
• Inefficient allocation across teams

We help our clients review actual usage across their business SIM cards. This helps you to identify where money is being wasted without affecting the performance of your team.

2. Consolidate business SIM cards, where possible

One of the most effective ways to reduce costs is consolidation.

Many organisations using business SIM cards end up with multiple providers, legacy contracts, or separate billing structures.

This creates:

• Duplicate costs
• Lack of visibility across the business
• Administrative overhead

We can help you to bring all your business SIM cards under a single provider. Consolidating and streamlining the structure makes it easier to manage usage, track spend, and reduce unnecessary duplication.

3. Align Business SIM Cards with Business Needs

Not every employee uses their phone the same way.

A common mistake with business SIM cards is giving everyone the same plan, regardless of role.

Instead:

• High-usage roles like sales or field teams need larger allowances
• Office-based staff often require far less data
• Occasional users may only need basic connectivity

We can help you to match your business SIM cards to real usage patterns, ensuring you are not overpaying for unused capacity across your team.

4. Remove What You Don’t Use

Over time, most businesses accumulate unused business SIM cards, devices, or forgotten contracts, which are the sources of wasted spend.

Common issues include:

• SIM cards are still being billed, but it is not in use
• Old devices are still attached to active contracts
• Duplicate numbers or legacy users that remain active on your account

These common issues are generating unnecessary costs. We can help you to regularly audit your business SIM cards to help eliminate these hidden costs and ensure you are only paying for what is actively needed.

How do I audit my business mobile phone bills?

If you haven’t reviewed your business SIM cards recently, there’s a strong chance your business is spending more than it needs to.

To audit your business mobile phone bills, start by reviewing each line on your account and comparing it against actual usage. Check data, calls, and active SIMs to identify unused numbers, overpaid allowances, or duplicate contracts. Then group your business SIM cards by user or role, remove anything no longer needed, and ensure each plan matches real usage, giving you a clear view of where you can reduce unnecessary monthly costs.
