It’s easy to forget just how expensive out of allowance calls are, but when you do the maths, it becomes clear. At best, you’ll pay 10p per minute for a mobile call out of allowance. How much do your in allowance minutes cost? Well, take, for example, Three’s 300 mix and match tariff. You get 300 minutes (assuming you just use calls) for £15. That’s 5p per minute of calling – half the price of a call made outside allowance. Therefore, if you make 450 minutes of calls, you’ll get a bill for £30! If you’d have gone for the £18 500 minute tariff, you’d still have 50 minutes to spare before you had to start paying for calls.

No matter which network you choose, it’s always worth thinking about choosing a larger tariff if you’re likely to go over the limit regularly.
