Costs associated with 0300 & 0303 numbers

Cost of Calling 0300 & 0303 Numbers from UK

Calls to 03 numbers cost no more than calls to geographic (01 and 02) numbers and must be included in inclusive minutes and discount schemes in the same way. Calls from landlines and mobiles are included in free call packages. It is also possible to call an 0300 or 0303 number from abroad.

How much does an 030 number cost?

Prices start from just £15 per month. More memorable 03 numbers cost more (i.e. platinum and ultimate numbers attract a higher monthly charge). You get 5000 free minutes when the 03 number is routed to a UK landline - this is enough for most small businesses. If you receive more calls then you simply pay 1.5p per minute for additional minutes.

Costs of Diverting Your 030 Number to a Mobile Phone

You can choose to route all calls to your mobile and receive up to 250 call minutes per month for no additional cost. Extra minutes used over the 250 limit are charged at just 6p per minute. If you wish to receive calls both your landline and mobile, select our Mobile250 package for an additional £10 per month. 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.
