SIM-Only Business Mobile Plans for UK Companies

That sits alongside the rest of our business mobile service: contracts, 5G and device management, all on a single monthly bill with one UK account team. If your handsets are still in good shape, SIM-only is usually the cheapest way to keep your fleet connected.

What's included in an AMVIA SIM-only business mobile plan?

Every AMVIA SIM-only plan covers airtime, inclusive data and UK business call rates, managed end-to-end so your IT team never has to deal with carriers directly. We handle network selection, activation, billing and renewals, and add optional device security on top.

• Negotiated business tariffs across all major UK networks, not consumer pricing
• Flexible data allowances from 5 GB to unlimited per user
• Number porting handled for you, with no service interruption
• Single monthly bill with usage alerts and a named account manager
• Optional device security via Microsoft Intune and mobile threat controls

This is where a security-first provider differs from a phone reseller: we treat each SIM as an endpoint on your network, not just a line on an invoice. Pair it with mobile device management and every handset is enrolled, encrypted and remotely wipeable from day one.

How does AMVIA set up SIM-only plans?

We start with your actual usage, not a generic package. Our team reviews current spend, picks the right network and tariff per user, ports numbers, and ships activated SIMs to your office or staff directly — typically within a few working days.

1. Usage analysis — we review current mobile spend and usage patterns to find the most cost-effective plans, often saving 30–50% vs consumer plans (typical UK 2026 range). 2. Network selection — we compare deals across all UK networks and negotiate business rates. 3. SIM delivery and activation — SIMs go to your office or staff directly, with number porting handled end-to-end. 4. Account management — one monthly bill, usage alerts, and a dedicated account manager for adds, changes and renewals.

SIM-only vs standard mobile contract: which is right for your business?

SIM-only is cheaper when your team already owns suitable handsets, because you only pay for airtime and data. A standard contract spreads a new device cost across the term, inflating the monthly fee. The right choice depends on handset age and how often you refresh devices.

If you do need new hardware across the team, our business mobile contracts bundle handsets, and our 5G business mobile plans cover field staff who depend on fast mobile data.

Why do UK SMEs need secure business mobiles?

Mobiles are a soft target. They carry email, Teams, files and saved logins, yet they often sit outside the controls applied to laptops. With 43% of UK businesses hit by a cyber breach or attack in 2025, an unmanaged phone is a real route in.

According to the DSIT Cyber Security Breaches Survey 2025, 85% of those breaches involved phishing — and phishing lands on phones as readily as desktops. The NCSC's device security guidance recommends enforced encryption, screen locks and remote wipe on every business handset.

That is why AMVIA treats SIM provisioning and security as one job. Enrol each device in Microsoft Intune — Microsoft's cloud device-management platform — apply conditional access, and you can lock or wipe a lost phone in minutes. Our business mobile security controls layer on top of the SIM, not as an afterthought.

How much does a SIM-only business mobile plan cost?

Pricing depends on data allowance, contract length and line volume, so we quote per estate rather than per advert. SIM-only is consistently cheaper than handset contracts because you are not financing a device, and pooled business tariffs beat consumer rates.

• Data tiers: 5 GB to unlimited, matched to each user's real usage
• Contract terms: rolling 30-day, 12-month or 24-month — mix across your fleet
• Typical saving: 30–50% vs consumer plans (typical UK 2026 range)

We can mix contract lengths across the estate so seasonal or temporary staff stay flexible while core users lock in lower long-term rates. Number switching in the UK is regulated by Ofcom, so porting is a defined, low-risk process we manage for you.
