4G LTE network issue in Galaxy A7 (2018).

[lakmal1992]

After I installed android pie update on my Samsung Galaxy A7 (2018) phone I can't use 4G LTE signal to connect with internet. 

My country is Sri Lanka and I installed Android Pie Update on 12th April 2019.

I tried to reset the network setting to default,  flight mode on / off. But the problem couldn't solve. 

Can you please help me to solve this problem.
