Bought my daughter her first phone and what a fantastic phone it is. Having used Xiaomi on o2 with no problems for the past two years I thought this would be the same with her new phone. Got her an iD contract to put in the phone but no matter what I do it doesn't work. I put the APN settings and getting a signal as soon as it boots up but it is almost like the operator is blocking the phone? It will show the iD network, signal and 4g for a few seconds then disappear. I can repeat this by restarting the phone every time so I am connecting. My o2 sim and the wifes 3 sim works absolutely flawless in this new phone how ever cannot get the iD sim to work at all.
