Why Compare?
Most businesses overpay on their mobile contracts by 20 to 35 percent. The main reasons are auto renewed contracts at inflated rates, data plans that do not match actual usage, and hidden charges. Comparing all four networks side by side reveals whether you are getting good value or paying more than you need to.
| What We Check | Why It Matters |
|---|---|
| Coverage at your postcodes | The cheapest deal is useless with poor signal |
| Data vs actual usage | Right sizing prevents overpaying and overage charges |
| Contract terms | Length, price rises, exit fees all affect total cost |
| Multi line discounts | 5+ lines typically save 10 to 25 percent |
| Business features | Fleet management, MDM, roaming, support levels |
Frequently Asked Questions
How much do 5 line business mobile deals cost?
The cost of a five line business mobile deal depends on the data allowances you choose and whether you want SIM only plans or new handsets. Business pricing is quoted excluding VAT. We compare EE, Vodafone, O2 and Three to find your best deal and confirm exact per-line prices when you enquire.
Can I mix SIM only and handset deals across my 5 lines?
Yes. Most networks allow you to mix and match within the same account. For example, you could have three SIM only lines for staff who already have phones, and two lines with new handsets. All five appear on one bill and you still receive multi-line pricing.
Do I get a discount for ordering 5 business mobile lines?
Yes. Five lines is typically the threshold where networks start offering meaningful multi-line discounts. Through Compare The Networks, five-line bundles unlock per-line savings of 10 to 25 per cent compared to ordering individual contracts.
Can I manage all 5 lines from one account?
Yes. All five lines sit under a single business account with one monthly invoice. You get a centralised management portal where you can view usage, set data caps, add or remove lines, and manage your account. This is far simpler than having five separate contracts.
What happens if I need to add more lines later?
You can add additional lines to your account at any time during your contract. New lines are added at the same or better per-line rate. If you grow beyond 10 lines, you may qualify for even deeper volume discounts.
Is there an annual price increase on 5 line deals?
Yes. All major UK networks apply a fixed price increase each April, added per line rather than as a percentage. It takes effect from the April after your contract starts. Because it is a set amount it is predictable and easy to budget for, and we'll confirm the exact figure for your chosen plan when you enquire.
