How long are mobile phone contracts?

Contract lengths will vary depending on the type of handset and pricing plan you've chosen.
Usually there are 12 or 24-month options and you'll pay a fixed price monthly for the duration of the contract length. However, if you go over your monthly data allowance or incur roaming costs, these charges will be added to your bill. Watch out for a minimum contract term and if you cancel before this ends you could be charged an early cancellation fee.
