In most cases you will find that you will be saving money with a SIM Only contract. Here are some example scenarios to help you understand where savings can be made:
Scenario 1 - You already have a phone and want to switch to a SIM Only deal.
With this example you will have already own a mobile phone from an old or existing mobile contract. The cost of the phone has already been paid for in this situation so we do not need to include this when calculating the total saving.
Let's assume your current price plan is with Vodafone and gives you Unlimited Minutes, Unlimited Texts and 8GB of data for £53 a month (plus a £9 up front cost). Now, this may have been a good deal because you got a phone with it a couple of years ago but now you have the opportunity to get a similar ( or better ) plan for a much cheaper monthly cost.
Having a quick search of the current SIM-only contracts you will find several contracts that have around the same minutes, texts and data for anywhere between £15 and £20 a month. Most deals in that price range actually have more data!
Now for the basic maths:
If you were to continue on your current contract for the next year your total cost would be: £36 a month x 12 months = £636.
Using a SIM-only plan on a mid-range 12-month contract would cost you: £15 a month x 12 months = £180.
Therefore your total saving for a year would be £636 - £180 = £456. This is a very significant saving just by keeping your phone and switching to a SIM-only deal!
Scenario 2 - You are going to buy a phone outright:
In this example you have either already bought a new phone outright on PAYG or SIM-Free or are going to purchase it. Let's assume you want to get the
iPhone 8 and you want to find out whether it's cheaper to get it on contract or SIM-free with a SIM-only.
Now, this situation is a little more complex than the first scenario as we need to take into consideration the cost of the device itself as well as the total cost of getting the phone on a typical 24-month contract. This is what we call the total cost of ownership or TCO if you like acronyms. :)
If you are looking to get an iPhone 8 with Vodafone for example, the cheapest tariff on a 24-month contract starts at £45 a month with a handset cost of £149 a month. With this deal you get 500 mins, unlimited texts and 500MB of data. With
Vodafone SIM-only you can get a cheaper monthly tariff for only £13 a month on a 12-month contract and get Unlimited minutes with 2GB of data.
This is a superb deal however, we still need to factor in the cost of the iPhone 8 and we all know that it's pretty expensive. The 64GB version has a retail cost £699.
Now for the maths:
The TCO for your mobile contract is: £149 + (£45 a month x 24 months) = £1229 over 2 years
The TCO for your SIM Free iPhone 6 and SIM-only is: £699 + (£14 a month x 24 months) = £1035 over 2 years.
In this scenario you would save £194 over 2 years. A very significant amount.
By switching to an even cheaper deal you will save a lot more money so it's important to make sure you are getting the right plan. Many people do not use the entirety of their allowance each month. The savings in this type of scenario are also dependant on the cost of the phone.
