This is a smartphone of 3.5 G supportive. May be my comment seems funny, but it’s true. This phone LTE service but not VoLTE service.
Means, you can use internet but can’t call when you’re offline.
Although, Battery condition is good. The talktime of battery is also good. Body is shaped to amazing slim.
Network problems also occur.
So, I can’t suggest to buy this phone.
