Hello,
Here is an example,
Sent a text to cell number 1234565 (my wife) and she will received the text without any problem. However, when she reply to my text, i will received her reply as new text message (i.e. 123456@vtext.com). I checked both our phone address books and cannot find any address with @VTEXT.com. I also added the vtext address into my wife address book and same issue. Once in a while, I will receive the reply correctly.
I cannot figure out why this is happening. Started happening after we both upgraded our phones to Samsung S4. Any help will be great...
