As a GiffGaff customer, you may have a tariff or bolt on which is known as a Goodybag. If this is the case, then lucky you because you will not be charged for your call! This is because your time spent calling an 0333 number would come straight out of your Goodybag tariff until you run out for that month. A goodybag on GiffGaff is a worthy investment if you are looking to make lots of calls to 0333 numbers as this would make it far cheaper for you in the long run.
All Goodybag allowances are different, but in this instance, they do allow you to call any UK numbers starting with 01, 02, 03 from GiffGaff without worrying about the cost in the meantime.
If you are interested in purchasing an 0333 number, our team will be able to assist you to pick the best for your business and your needs.
