Guide to preventing 'bill shock' when using your mobile phone

More consumers than ever before are signing up to contracts for mobile phones.

These deals have a number of advantages - the handset is often free or subsidised, you get inclusive minutes, texts and data each month, and it can be more convenient than topping up your phone credit.

But there are times when you can face paying more than you were expecting - known as 'bill shock'.

Mobile phone bill

Using more than your monthly allowance - whether it's through more data (accessing the web, emails, apps, music etc from your phone), making more or different types of calls, using your phone abroad or being a victim of phone theft - can all result in a bigger bill.

The following guides explain how you can avoid these key causes of 'bill shock'. They offer advice and tips covering four areas:

  • Preventing bill shock when using your phone at home in the UK
  • Preventing bill shock when using your phone abroad
  • What to do if your phone is lost or stolen and how to protect your phone from thieves
  • What to do if you do get stuck with an unexpectedly high bill.
