I never received a text about being upgraded to unlimited minutes, but I can also see that it's unlimited now on the AT&T website in the rate plan area. Usage still looks like I'm over my 700 allotted minutes and dipping into my Rollover, so I wonder what it will look like when the Rollover is used up.
I was curious about some people being upgraded to unlimited text. I have a 200 text plan on my line, but the other 3 lines have texts blocked so they don't accidentally receive unwanted texts at 20 cents a piece. I removed the block on one of the lines, and it looks like that line automatically has unlimited texts now! I'll wait for a billing cycle just to see if it sticks, and if it does, I'll take the gamble and remove my 200 text plan to see if I get unlimited too.
Update: Actually, it looks like the texts are being charged at 20 cents each. It took a few hours to show up.
