BYOD vs. Corporate Phones: The Hard Math
Traditional contracts bundle expensive hardware and unwanted data packages. Here is how a 10-person UK team compares over 12 months.
| Cost Category (10 Seats) | Traditional Corporate Handsets | SecondSim BYOD eSIM |
|---|---|---|
| Handset Hardware Costs | £2,000 upfront (10 x £200 budget handsets) | £0 (Staff use personal devices) |
| Monthly Line Rental | £5,400/yr (£45/mo x 12 mos x 10 staff) | £600/yr (£5/mo x 12 mos x 10 staff on Yearly Plan) |
| Insurance & Repairs | Approx. £600/yr (Replacements & breakages) | £0 (Employee personal phone responsibility) |
| Total Year 1 Outlay | £8,000+ | £600 |
| End Result | High CapEx, administrative tracking hassle | 92.5% Cost Reduction. Zero asset management. |

Frequently Asked Questions
B2B Cost & Setup Questions
How do eSIMs save businesses money compared to traditional contracts? +
Traditional B2B mobile contracts bundle the cost of expensive handsets and excessive data allowances. With SecondSim, you only pay for the business number and call plan, utilizing the employee's existing device.
Can employees keep their personal numbers private with BYOD? +
Yes. Our eSIM acts as a completely separate cellular line on their smartphone. All business calls, texts, and WhatsApp conversations run entirely through the SecondSim profile, ensuring complete separation from their personal life.
Is SecondSim a VoIP service or a real mobile network? +
SecondSim operates directly on real UK mobile network infrastructure (Vodafone UK core). It is not a VoIP app. This ensures 100% reliable SMS 2FA delivery from banks, WhatsApp Business, HMRC, and Stripe.
How accurate is the business mobile cost calculator? +
The calculator uses published 2024/2025 B2B pricing averages from major UK networks (EE, Vodafone, O2). It accounts for typical handset upfront capital expenditure and monthly line rentals to provide an accurate estimate of Year-1 cash savings.
