I have MX3 CN one, bought in China. i have the problem when i got back to Europe that there is no network connection, when I try manually to find network operator it founds, but choosing any of them leads to note " cannot connect, please try later". This happens with both of my sim cards either Chinese and European.
I already upgraded firmware, cleared all data and settings, nothing. May it be problems with the network operators? Maybe someone experieced it and can help me. Thank you in advance
