I have a smart app that turns off cellular when my home wi-fi is detected.
So, cellular was off and I wanted to text a pic to someone and when I tried to send I got a box that said I couldn't send a pic because my data was turned off, and to allow data and try again.
I wasn't sure where to look,but I tried going to settings>mobile>mobile data on and tried to text the pic and it worked (lucky guess). So after I had sent the pic I set mobile data to off again.
Can you not text a pic over wi-fi? That sux if you can't send over wi-fi.
I try to use wi-fi whenever I'm close enough to connect to save my monthly data usage.
