Assalamu Alaikum.
This mobile is a 5G set, OnePlus 8 5G. There are no problems with this phone, it is fully fresh, just has a green line and the back part broke after falling from hand. You can change it if you want, but I didn't change the back part regarding the network, as I got very good network with this. If anyone wants to take it, please let me know. koma te
