FreedomPop believes in rewriting the rules of mobile phone services ever since it was established in 2011. It currently uses the 4G LTE network and works to create free data not only on mobile phones, but also with Dropbox and Skype.
However the way 0844 are organised prevents them from being free. For these type of calls there is an access charge and service charge which will eat into your allocated minutes. The price of the access charge must be shown wherever the phone number is advertised, the price of the service charge is 45p (the same as the Three network). So it worthwhile to make as few 0844 calls as possible
