What should you compare before choosing? Coverage
Coverage matters more than price. Check network performance at your office, home-working locations, client sites, event venues, rural areas and regular travel routes.
Data allowance
Do not overpay for unlimited data if staff only use email and calls, but do not under-buy if teams use mobile hotspots, Teams, maps, CRM or video calls.
Contract length
Longer contracts can reduce monthly costs but make it harder to switch. Shorter rolling plans are useful for contractors, temporary staff and project-based teams.
Roaming
Check whether EU roaming, international roaming, fair usage and calls abroad are included. Vodafone says all of its business mobile plans include international roaming options, while Three offers roaming options on business multibuy SIMs.
Handsets
If you need iPhones, Samsung Galaxy or Google Pixel devices, compare the total contract cost rather than just monthly line rental.
Support
Small businesses may be fine buying direct, while larger teams may need managed support, billing help and account management.
Annual price rises
Check annual price-rise terms before signing any mobile contract, especially for 24-month and 36-month deals.
