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 many lines do I need for a multi-line business mobile discount?
Most UK networks start offering multi-line discounts from 5 lines. Discounts typically range from 10% for 5-9 lines, 15% for 10-24 lines, and up to 25% for 25+ lines. Some networks offer bespoke pricing for fleets of 50+ devices. Contact us for a personalised quote.
What is a shared data pool for business mobiles?
A shared data pool allows multiple SIM cards on your business account to draw from a single combined data allowance rather than each having an individual limit. For example, a 100 GB shared pool across 10 lines means the total group uses 100 GB collectively. This is efficient when some employees use more data than others.
Can I mix different plans on a multi-line business account?
Yes, most networks allow you to mix SIM only and handset deals, as well as different data allowances, on a single multi-line business account. This lets you tailor each line to the individual employee's needs while still benefiting from the volume discount on the overall account.
What fleet management tools are included with multi-line deals?
Networks provide online portals where you can manage all lines from a single dashboard. Features include usage monitoring, spend caps, bar certain call types (premium rate, international), add or remove lines, and view consolidated billing. For larger fleets of 25+, some networks include Mobile Device Management (MDM) tools for remote device configuration and security.
Do multi-line discounts apply to SIM only deals as well as handset contracts?
Yes, multi-line discounts apply to both SIM only plans and handset contracts. You can mix both types on the same account and still qualify for volume pricing. The discount is based on the total number of lines on the account, regardless of whether each line is SIM only or includes a handset.
