hi... try with other sim card, if still the problem may be the antenna,

if you do not know how to repair it, carry it with a good technician for review.

or give us more information of the problem!

lucky! I hope you understand me!

I happens with all sim cards, i looked around on the internet and found that if you flash it with specific Z780i firmware it will give it full signal

that problem came from software itself (i.e. after unlocking) well it can't be the same problem as yours or might be same but you can try what they do, it would be best if you narate the history of your phone, how it came to this problem and so on.
