Costs associated with 0300 & 0303 numbers

Cost of Calling 0300 & 0303 Numbers from UK

Dialling 03 numbers costs no more than calling geographic (01/02) numbers, and mobiles can use inclusive minute bundles. It is also possible to call an 0300 or 0303 number from abroad.

How much does an 030 number cost?

Prices start from just £10 per month. More memorable 03 numbers cost more (i.e. Platinum and Ultimate numbers attract a higher monthly charge). With our Platinum offering you get 2500 free minutes when routing the 03 number to any UK landline, or 500 minutes if routing to a mobile or landline. For calls exceeding the 2500 landline minute bundle then you simply pay 1.5p per minute (billed per second).

Costs of Diverting Your 030 Number to a Mobile Phone

Instead of the Platinum 2500 landline only bundle, you can choose to route all calls to either your mobile or landline and receive up to 500 call minutes per month for no additional cost. Extra minutes used over the 500 limit are charged at just 4p per minute. There is also the option to use our Pay as You Go service (perfect if you wish to divert to your mobile on an occasional basis) - diverted calls are charged at 9.95p per minute. View Mobile Divert Costs.

Fax To Email

You can also choose to use a 030 number as a Fax to Email line, where faxes are received via your email. This is a great alternative to having a fax machine, which is traditionally expensive what with the on-going maintenance and material costs. What's more, you don't need a physical landline if you choose Fax to Email, again, saving you a lot money.
