I’m the same, been like this most the afternoon and my phone is the main business phone for 2 businesses. Mobile data is fine, can make and receive calls via WhatsApp but can’t make or receive normal voice calls. Has anyone got in touch with Three yet to find out what the problem is as the online chat is useless!!
