HI I bought a tmobile ZTE concord for a senior family member of mine.
She has a texting plan but NOT a data plan. ALso, she does NOT have wifi at home.
It appears that this voice to text feature does not work UNLESS you have a data plan OR using wifi.
WHen I tested it in a wifi area The voice feature worked as it should.........

Here is my question. Is there an app something I can download so that she can use voice to text?
I have searched for apps but dont know what to get.
I appreaciate all the ideas you can give. I dont want to root her phone.
Thanks in advance
