Sometimes your bill might be higher than you expected. This could be because of charges that have occurred outside your monthly tariff allowance. You can find out how much you’ll pay for calls, texts and data outside your bundle in our extra charges guide.
Here are some of the most common reasons for having a higher bill:
The most common reason for an unexpectedly high bill is going over your monthly allowance of texts and minutes. When this happens, you'll be charged at our standard rate. Go to My O2 to check your usage and tariff.
Premium services including entering TV competitions, donating to charity or calling a service number. These services are outside your normal tariff allowance, so you’ll be charged extra for them. If you’ve got a premium service charge on your bill, you can use our online tool to find out more about the provider. Find out more about premium rate services.
Charge to Mobile lets you buy digital content like apps, games, music and movies, then pay for it through your phone bill. Find out more about Charge to Mobile.

There’s no charge to call 080 numbers from your mobile or landline. Find out more.
All standard UK landline numbers start with 01 or 02, and all UK mobile numbers start with 07. Calls and texts to these numbers are included in your minutes and texts as part of your tariff. If you go over your allowance, you'll be charged at our standard UK rate.
There are some exceptions where you'll be charged for calling or texting 01, 02 and 07 numbers. For example, if the number is in Jersey, Guernsey or the Isle of Man, of if it's being used as a call forwarding service, you'll be charged extra.
Calls to 03 and 070 numbers cost the same as other standard fixed line numbers starting 01 or 02, and are included in your minutes and texts as part of your tariff.
Some phone numbers are operated by third parties who connect or forward calls to another number. There are lots of these third-party services and they charge our network a different, higher rate to connect calls. Calls to these non-mobile and call-forwarding services are not included in your inclusive minutes. See 07 numbers for non-mobile and call forwarding services.
Monthly price of your Airtime Plan will increase by £1.80 each April, except Data Only and Smartwatch Plans which will increase by 75p. Out of bundle charges increase by 5% every 1 April. Find out more about API.
