SIM-Only Business Mobile Plans for UK Companies
AMVIA delivers this service as part of our managed IT portfolio for UK businesses. Fixed monthly pricing, no hidden fees, and a team that understands your business.
SIM-only business mobile contracts provide UK companies with competitive call, text, and data allowances on existing devices — without the cost of new handsets.

Frequently Asked Questions
A SIM-only plan provides airtime, calls, and data without a bundled handset, resulting in significantly lower monthly costs. Standard contracts spread the cost of a device over the agreement term, which inflates the monthly fee. SIM-only is ideal when your team already has suitable handsets or when you prefer to purchase devices separately. SME IT support costs typically range £35–£65/user/month for fully managed services (industry benchmark), and SIM-only plans help keep overall per-user costs down.
AMVIA offers business SIM-only plans with data allowances ranging from 5 GB to unlimited, depending on your usage requirements. Field-based workers and heavy data users benefit from larger allowances, whilst office-based staff who primarily use Wi-Fi may need only a modest plan. We analyse your team's historical usage and recommend the most cost-effective allowances for each user.
Monthly SIM-only plans are almost always more cost-effective for businesses because they offer lower per-minute call rates, inclusive data, and predictable billing. PAYG can suit temporary workers or devices with very low usage, such as alarm SIMs. 43% of UK businesses experienced a cybersecurity breach or attack in the past year (DSIT 2025), and monthly plans make it easier to include device management and security controls.
Yes. AMVIA manages the number porting process from your current provider, which typically takes one to three working days for mobile numbers in the UK. Your team keeps their existing numbers with no interruption to service. We coordinate the porting date to ensure a seamless switchover, and temporary SIMs can be provided if needed to bridge any gap during the transition.
Business SIM-only plans are available on rolling 30-day, 12-month, and 24-month terms. Rolling contracts offer maximum flexibility for seasonal staff or businesses that expect headcount changes, whilst longer terms provide lower monthly rates. AMVIA can mix contract lengths across your mobile estate so each line is on the most appropriate and cost-effective term.
