Yes. Whether it’s a UK pay by phone casino or a European site, all processors are 100% legal. There are two reasons for this. Firstly, all pay by mobile casinos have to be licensed by an official regulator such as the UK Gambling Commission (UKGC). Secondly, Boku, Zimpler and Payforit have all been assessed and authorised by the mobile industry. Because deposits are being charge to your phone bill, processors need to have agreements with major mobile networks. By working with Vodafone, EE and other big businesses, pay by phone processors are given an extra layer of legitimacy.
