Typically, when you take out most mobile phone deals, you pay by monthly direct debit. This is the cheapest and most convenient way to pay with peace of mind you’ll never forget to make that important payment.

You’ll pay the monthly payment for your included minutes, texts and data.

How you use your phone will determine what you will need. Are you a big talker or a heavy texter? Stream lots of video on the move?

If you talk more than you text, make sure you go for a plan with a generous allowance of minutes to make sure you don’t go over your limit. Text more? Make sure to get lots of texts, or a package with unlimited texts.

If you burn through your data, its best to go for a 4G contract with unlimited allowance to make sure you’re not hit with any nasty surprises on your bill

Most networks nowadays offer quite good mobile phone contracts with inclusive minutes, texts and data. Just be sure you choose the right one for you.

Contracts are typically 12 or 24 months. The reason for this is that the price of the new phone that comes with your allowances is factored into the price. Most people enter into 24 month contracts as this spreads the cost over 2 years, resulting in smaller monthly payments.

You want to make sure you can get a reception to even be able to use your phone. Some parts of the country, particularly rural areas struggle with network reception. You can view the coverage available in your area here.
