Which is cheaper – a business or personal mobile phone contract?

Switch My Service can help businesses of all sizes save on their business mobile & landline costs, but a common approach some businesses take to save on mobile costs is to use contracts & plans intended for personal use.

If you are shopping around for a single handset, sometimes a business contract can be cheaper – particularly for high value handsets with unlimited data – but other times a low value SIM only contract can be cheaper on a personal tariff.

Therefore, as with so many things in life, the simple question of “is a personal contract cheaper than a business tariff?” has that most frustrating of answers – it depends.

What factors affect which is cheaper?

When it comes to a simple comparison of one phone number on a 36-month contract, shopping around between both personal & business contracts will deliver the best possible monthly rate – particularly if you are genuinely agnostic as to the terms of your contract and are governed solely by price.

However, business contracts are designed to be easily scaled where extra SIM cards and handsets can be added which activate bulk discounts, so where a personal contract may be cheaper for a single phone number, as your business grows the need for a business contract will increase – and the cost effectiveness of a business contract will grow.

Additionally, should you choose to scale your business by adding more & more individual personal contracts, managing this portfolio of assets will get harder and harder. This is opposed to having a single business contract with a single avenue of support which can make your life much easier and save the business both time & money.

In conclusion

For sole traders or businesses with a single phone number, it can pay to search around between personal & business contracts to find the cheapest deal as it isn’t as simple as saying “a business contract is always cheaper than a personal deal.”

However, larger businesses with multiple phone numbers will benefit from the cost savings that come from having a business contract for their mobile phone and the additional support often provided to business customers will make life easier.
