The cost of calling an 0300 number, whether bought from Number Supermarket or not, from a mobile phone depends on several factors including:
• what network you are with
• whether you are on a monthly contract, or are a pay as you go customer
• whether you have available minutes available in your monthly allowance
• whether you are calling from the UK or from abroad
The important thing to note is that 0300 numbers are regulated in the same way as local numbers that start 01 or 02. It doesn’t cost you any more to call an 0300 number than an 01 or 02 number.
Phone companies have to include calls to 0300 numbers in any deals, packages, or bundles that also include calls to local landline numbers. However, outside these deals, calls to an 0300 number from a mobile can cost from 3p per minute to 40p per minute.
