I am having a Acer Liquid E2 Duo smartphone. It came with dual band gsm and 3G support. Recently I traveled to US. The phone works well in my region but as I moved to other country the 3G stopped. There was no issue with the gsm. I want some help here to fix this thing. Where is the problem. Is it with the device or with the telecom provider. I can contacted Acer support but they don't have any answer for this.
