It has worked perfectly work my Kenyan Safaricom SIM, and my UK Vodafone SIM. I have changed into a contract provided by EE in UK (iD SIM from Carphone Warehouse) , yet the phone does not recognise my SIM is in the phone. I am in my second SIM from then, and the phone still states 'No SIM card - No Service'. The SIM did work in a Samsung however. I have even checked the Service Info SIM Lock, with all five words ending in '0' which I believe shows it is not carrier locked. The Rooting status states the "Bootloader unlock allowed: Yes". So please can you help me to figure out why my iD SIM(s) doesn't work?
