I was an ID mobile customer for while, when I found a better deal somewhere else I informed ID mobile on time as it's a monthly contract. On my last day I removed the ID SIM from my mobile phone. Now ID mobile charged for so called " rental line" and said if I don't pay the debt collector will recover the amount for them. I know ID mobile is a monthly contract SIM, and I owed ID mobile nothing. Just waiting for the debt collector to contact me and I'll email all the conversations I had with ID mobile. ID mobile is not an honest company and I'll never get back to it again even it becomes the cheapest network in the UK.
