How to update umi diamond x quad core specs

When I put in the SIM card for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to “preferred network type” there is only 3G to pick, and THE MOMENT I PICK IT its not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that’s a software problem right? Message 3 of 12
