Sorry to invade your thread so to speak but im pulling my hair out here. Basically I got my mi note last week and had problems getting it to recognise my three uk sim - vodafone and EE were fine. So - I sent the handset back and got a new sim. New handset arrived yesterday and guess what - it still wont recognise the sim. Ive tried all the usual ie select GSM / LTE etc only from the testing page on the dialler but nothing....am i going crazy or is this phone just not compatible with three uk?
