Complaints not answered and addressed for months, bought an unlimited internet sim for my Sim router (was with three 'broadband'), ID mobile tell me after the contract starts the sim is not meant for that and they wont support that. Calls to the customer service complaints team (0800 049 1300 - they gave it to me following a complaint / reply it takes 50 mins+ to get through to someone on their phoneline). I regret taking out this contract, Customer service and complaints team response is poor and inadequate; Their customer service is nonexistent they have an automated online chatbot who will eventually put your through to a online person. There was a lot of confusion, agent said they would raise this and get back to me within 24 hours, i had the start all over again on the chatbot which was eventually raised higher. As i said i use this for internet connection, the signal keeps going down and the speeds are extremely slow and inconstant (compared to Three on the same router previously in the same location). I believed that ID mobile use the same networks as 'Three' however ID mobile were at pains to tell me that they are not the same etc.
