Calls to 084 and 087 phone numbers are not included with the UK sim card because they are not UK landline numbers.  084 and 087 numbers are called "shared rate numbers" which are similar to Australian premium rate 1900 numbers.


084 and 087 numbers incur an additional per minute rate charged back to the company/business you are calling.  Effectively the company/business makes money out of your call!  The additional cost can be as high as 15p/minute.


But don't worry!  Every 084 and 087 number has a corresponding UK landline number.   You can find the corresponding UK landline number usually on the company/business website (look for the number to call for people from overseas), and you can also locate the UK landline number for the business / company by clicking and searching here.
