Across our customer onboardings, the same patterns come up repeatedly:
Handset financing is baked into the monthly bill – often equivalent to 30-40% interest over 24 months. Most businesses don’t realise until it’s pointed out.
The “upgrade every 24 months” cycle is rarely necessary – most business users don’t need a flagship camera to make calls, send emails, and run Teams.
Switching to SIM-only lets businesses keep working devices and stop paying for handset upgrades they don’t need.
A corporate eSIM on a personal handset gives the business a dedicated work line — without provisioning a second device.
With proper MDM in place to keep work data separate, staff use their own phones with a corporate eSIM for calls and data — no second device, no procurement cost.

Recent customer switches from bundled contracts to SIM-only:
35 lines · Financial services
Migrated 35 lines from a bundled contract with significant out-of-bundle international charges to an EE Business SIM-only All Rounder plan. The SIM-only structure also absorbed previously volatile international call costs into a predictable fixed tariff.

yearly saving
12 lines · Manufacturing
Engineering firm with operations across the UK, USA and Europe moved 12 lines to a 12-month SIM-only contract with 100GB data per SIM at £21/line. The shorter contract also avoided scheduled RPI inflation increases and decoupled their handset inventory from airtime renewal cycles.

Different industries make different decisions about networks, data tiers, and contract structure based on real usage patterns. Here’s how we typically advise, drawn from active accounts across our customer base:
Coverage breadth matters more than peak speed whendrivers and field teams cover the whole country. National coverage and reliability tend to drive network selection. Vehicle trackers, route management apps, and dashcam upload all benefit from solid data allowances — though most teams use 20-50GB/line rather than unlimited, paired with M2M SIMs for in-vehicle hardware.
Reliability and indoor coverage are the deciding factors – staff need consistent signal across care facilities, hospitals, and patient visits. Dedicated work lines on SIM-only contracts pair well with BYOD policies where staff use personal devices, with eSIM increasingly the preferred setup. Data needs vary significantly: clinical staff use modest data; community-based teams using video consultations need
more.
Site-based coverage matters most — manufacturing facilities are often in industrial estates where some networks underperform. Most manufacturing customers prioritise reliable connectivity for shop-floor and warehouse staff, plus office teams. Data usage tends to be modest (calls, email, internal systems). Contract length typically longer to lock in rates across larger headcount.
Rural coverage is the deciding factor for engineers and trades teams working across mixed terrain. Data needs depend on whether the work involves diagnostics, photo/video upload, or just calls and messaging – but most field teams benefit from higher data allowances than office staff.
Staff turnover means contract flexibility and easy line management matter as much as headline price. EPOS systems running over mobile, plus staff phones, plus pooled data across the team are the common pattern.
High call volumes, modest data needs. Unlimited calls with a 10-20GB data tier typically beats unlimited data on cost. Office-based teams with occasional travel.
Predictable monthly costs, compliance-friendly account management, and absorbing international call costs into fixed tariffs are the typical drivers. SIM-only structures decouple hardware procurement from airtime, simplifying both balance sheets and audit trails.
Honest advice after 26 years of selling business mobile contracts:
Field teams who stream video or upload large files. Hospitality teams running EPOS or POS systems over mobile data. Anyone using their phone as primary internet (mobile broadband, 5G routers for backup connectivity).
Office-based teams with mixed usage patterns. Heavy users get covered without paying per-line unlimited rates for light users. Most cost-effective for accounts of 10–50 users where individual usage varies significantly.
Across our customer base, the typical handset stays in service for 3–4 years — up from about 2 years a decade ago. Modern phones stay viable well past the standard 24-month contract.
Over half (51%) of our customers have 1–2 lines, and 73% have 5 or fewer. The remaining 27% scale from mid-sized teams through to 100+ user corporate accounts.
Average per-line cost drops from £27/line for accounts under 25 lines, to £17/line for 26–100 lines, and £9/line for 101+ user accounts. Multi-line discounts compound significantly at scale.
85% of accounts choose 36-month terms, with 15% on 24-month contracts.
85% of customers select capped tiers matched to actual usage rather than defaulting to unlimited — most business users don't burn through enough data to justify the premium.
