Best Business Mobile Deals This Week UK: Compare & Save (Updated April 2026)

Updated: 14 April 2026 — Prices verified this week. We refresh this page every Monday with the latest business mobile deals from all major UK networks.

Finding the best business mobile deal shouldn’t mean hours of comparing tariff sheets from every UK network. Whether you’re equipping a sole trader with a single SIM or rolling out 200 handsets across a growing enterprise, this weekly comparison cuts through the noise with real prices, honest verdicts, and clear recommendations.

At Connection Technologies, we’re an independent UK B2B telecoms provider — meaning we compare deals across all major networks (EE, Vodafone, O2, Three, and BT Business) and negotiate bulk pricing our clients can’t access directly. Every deal listed below is available through our team, often at a lower rate than going direct.

What Are the Best Business Mobile Deals This Week?

Below you’ll find our curated comparison of the top business mobile deals available in the UK right now. We’ve split the table into SIM-only deals and handset deals so you can quickly find what’s relevant. All prices exclude VAT (as is standard for B2B contracts) and are based on 24-month agreements unless stated otherwise.

Best Business SIM-Only Deals — April 2026

Our pick for SIM-only: Vodafone Business Evolve at £18/month. It delivers 100GB of 5G data, excellent fleet management via the Vodafone Business Hub portal, and competitive EU roaming. For pure budget, Three’s £10/month deal is hard to argue with.

Best Business Handset Deals — April 2026

Our pick for handset deals: EE’s iPhone 16 Pro plan at £42/month. Yes, it’s the priciest on the list, but EE’s 5G coverage (the UK’s largest) and the inclusion of 100GB makes this the professional’s choice. On a tighter budget, Vodafone’s Samsung Galaxy A56 at £22/month is outstanding value.

Which Network Has the Best Business Mobile Coverage in the UK?

Coverage matters more than headline price if your team works across multiple locations or travels frequently. Here’s how the four major UK networks compare for business users in April 2026:

EE — Best Overall Coverage

• ✓ UK’s largest 4G network — 99.8% outdoor population coverage
• ✓ UK’s widest 5G network — available in 500+ towns and cities
• ✓ Consistently fastest average speeds in Ofcom/Opensignal testing
• ✓ Dedicated Business Hub with spend controls and usage alerts
• ✗ Premium pricing — typically £4–£8/month more than Three for equivalent data
• ✗ EU roaming charges apply on cheaper plans

Best for: Businesses needing guaranteed connectivity nationwide, especially field service teams, delivery fleets, and remote workers in rural areas.

Vodafone — Best for Fleet Management

• ✓ Excellent 4G coverage — 99.5% outdoor population coverage
• ✓ Rapidly expanding 5G in 120+ locations
• ✓ Industry-leading Business Hub portal for managing multiple lines
• ✓ Flexible data pooling across team members
• ✓ Competitive mid-range pricing
• ✗ 5G footprint still significantly smaller than EE
• ✗ Customer service scores lag behind EE in Ofcom surveys

Best for: SMEs and mid-market businesses managing 10–100+ lines who value central administration tools and data sharing.

O2 — Best for Flexibility

• ✓ 12-month contract options available (rare in B2B)
• ✓ Strong 4G coverage — 99.4% outdoor population
• ✓ O2 Priority perks add employee benefit value
• ✓ Flexible bolt-ons for international calling
• ✗ 5G rollout slower — approximately 200 locations
• ✗ Slightly higher per-GB cost than Three or Vodafone

Best for: Businesses that prefer shorter contracts, startups unsure of their long-term needs, and companies with international calling requirements.

Three — Best Value and Best Unlimited Data

• ✓ Cheapest unlimited business data plan in the UK at £16/month
• ✓ Budget SIM-only from just £10/month for 30GB
• ✓ Strong 5G speeds in covered areas
• ✓ No annual price rises on fixed-price plans
• ✗ Weakest 4G coverage of the four networks — 98.8% outdoor population
• ✗ Indoor coverage can be patchy in rural and semi-rural areas
• ✗ Business management tools less mature than Vodafone or EE

Best for: Budget-conscious businesses based in urban areas, data-heavy users (mobile hotspotting, video calls), and companies prioritising cost over coverage.

How Much Do Business Mobile Deals Cost in the UK?

Business mobile pricing in the UK in April 2026 typically falls into these ranges:

• SIM-only (30–50GB): £10–£16/month per user
• SIM-only (100GB+): £18–£24/month per user
• SIM-only (Unlimited): £16–£28/month per user
• Handset + plan (mid-range phone, 50GB): £22–£30/month per user
• Handset + plan (flagship phone, 100GB): £34–£48/month per user

These are the published prices. Through an independent B2B telecoms provider like Connection Technologies, bulk orders of 5 lines or more routinely attract 15–30% discounts off list prices, plus extras like free handset upgrades, waived upfront costs, or data boosts.

All business mobile costs are VAT-reclaimable, so the effective cost is lower than consumer plans — an advantage many small businesses overlook.

Should I Choose SIM-Only or a Handset Deal for My Business?

This depends on your current hardware situation and cash flow preferences:

Choose SIM-only if:

• Your team already has recent handsets (less than 2 years old)
• You prefer to buy handsets outright and claim the VAT back separately
• You want the lowest possible monthly outlay
• You prefer flexibility — SIM-only contracts are often available at 12 or even 1-month rolling terms

Choose a handset deal if:

• You need to equip new starters or refresh ageing devices
• You prefer to spread the handset cost over 24–36 months
• You want a single, predictable monthly bill per employee
• You’re ordering 5+ devices and can negotiate bulk handset discounts

Our recommendation: For most businesses ordering 5+ lines, a handset deal through an independent provider like Connection Technologies offers the best total cost of ownership. We regularly secure £0 upfront costs and discounted monthly rates that make handset bundles cheaper than buying devices separately.

What Is the Best Business 5G Deal in the UK?

5G is now a genuine productivity tool for UK businesses — enabling reliable video calls from mobile hotspots, faster cloud application access, and even temporary broadband replacement in areas with poor fixed-line connectivity.

The best business 5G deals in April 2026 are:

1. Three Business Unlimited 5G — £16/month: The cheapest unlimited 5G business plan in the UK. Ideal if you’re in a Three 5G area.
2. EE Business Max 5G — £24/month (150GB): The most widely available 5G network. Pay more, but you’ll actually get 5G in more places.
3. Vodafone Business Evolve 5G — £18/month (100GB): Strong middle ground between price and coverage.

Best 5G deal overall: For urban businesses, Three at £16/month for unlimited data. For businesses needing 5G coverage everywhere, EE at £24/month.

Why Use an Independent Provider Like Connection Technologies?
