If you're a Pay Monthly customer, you'll be automatically registered.
If you're a Pay As You Go customer, you'll need to register using:

• your O2 mobile number
• an email address
• a secure password.

You’ll now see a single bill from O2, where your Airtime Plan and Device Plan charges are shown together as one monthly cost.

Signing in to My O2 is still the quickest way to view your latest bill. You’ll be able to see your bill total, your issue date and payment due date. You’ll also still be able to download your bill from the ‘Latest Bill’ page.

You can view individual device charges assigned to any number on your account. And, also see a breakdown of the charges for your Airtime Plan, Monthly Extras or the cost of your Device Plan, on the ‘Summary of Charges’ page.

You’ll get your first bill within four days of joining O2, and you’ll be charged 14 days after you receive it. Your official billing date is usually the date you joined us, and it will be the same every month.

If you joined us on the 29th, 30th or 31st of the month, your official billing date will be the 1st of the following month. Your first bill will be pro rata, which means that we’ll charge you for one full month’s airtime, as well as any airtime you use in those first few days before your billing cycle starts.

If you’ve upgraded your device, your billing date will stay the same. Your next bill will be pro rata and might include a charge from your old tariff or airtime charges.

You can view this on your ‘Summary of Charges’ page in My O2, where you can see your total bill broken down by:

• Tariff charge – cost of your data, minutes and texts

• Monthly extras – any additional spend outside of your tariff or device costs

• Device plan – the cost of your phone or tablet

These three payments are combined into a single bill total and will come out of your account on the same day.

The best way to keep an eye on your bill is to use My O2. You can see what you’ve been charged for, when to pay and how to pay. You can download the My O2 app for free, or text MYO2APP to 202.

If you joined O2 or upgraded your device after 23 January 2014, your bill will be adjusted every April by the Retail Price Index (RPI) rate of inflation announced in February. On O2 Refresh, your Device Plan payments are not subject to inflation and remain at 0% interest.

For information about extra charges that might appear on your bill, take a look at our other numbers and charges page.

Take a look at our payment date and billing date page for more information.

You’ll get your final bill 14 days after you’re disconnected.

If your Direct Debit’s still active, we’ll take the money from your account as normal. If you've cancelled your Direct Debit then you’ll need to call us to pay your final bill.

You can check your final bill online in My O2, but not in the My O2 app, as it’ll stop working once you’re disconnected.

Your final bill might be higher than your previous bills as it includes:

• the final cost of line rental
• any outstanding charges
• any cancellation fees.

Sometimes your final bill can be produced in credit. If this happens, take a look at our Final bill refund page for more information.

You can request a paper copy of your bill. It costs £2 for a summary bill and £2.50 for an itemised bill. If you still want a paper bill, contact us.

You can download and print a paper copy of your bill from My O2.
