Frequently Asked Questions

What is an 03 number? Will I be able to call it for free?
† 03 numbers were introduced in 2007 as an alternative to 01/02 numbers but not tied to any specific area of the country. We’ve checked all the big phone providers and they include calls to these numbers in your free minutes, but please check with yours to be sure. If you’re still concerned you can use 0117 395 0800 as an alternative number.
Can I still use your service if I don’t get free minutes to UK landlines?
Our access numbers should be charged at the normal landline rate, which may mean that you are charged for a landline call. Check with your mobile provider to find out how much you will be charged.
What’s the catch? How does 0800Buster.co.uk earn any money?
We can offer this to you as a free service because we receive a small amount of money for handling toll free calls.
How can I store your numbers in my phone’s address book?
Most mobiles come with the ability to add “pauses” to contacts which cause the phone to wait for 2–3 seconds before dialling the rest of the number. These are usually represented by a “p” or “+” so the number you store should resemble 03335558800p0800123456#. To enter a pause:


- press * three times (or until p appears)

Samsung, Motorola

- press and hold * until p appears

Sony Ericsson

- press and hold 7 until p appears


- press and hold # until p appears


- press and hold 0 until + appears

Apple iPhone

- press and hold * until , appears
Can I use your service to call 0845, 0870, or other UK numbers?
Unfortunately it would cost us money to handle these calls so we cannot offer it as part of our free service. You can, however, use our parent company Localphone.com to make cheap calls to the UK which should work out considerably cheaper than using your mobile directly.
What are some useful numbers I can call with 0800Buster?
You can get free directory enquiries from your mobile by dialling the 0800Buster access number, followed by 0800 118 3733.
What if I have questions, comments, or other feedback?
You can ask questions, report problems, or share your thoughts with the 0800Buster Community.
