Besides my real iPhone plan, I am using the sim from a GoPhone in a 3G iPhone. Everything works including SMS/MMS and even data.
Today I got a text from AT&T informing me that I could sign up for unlimited media net for $19.99 a month. I was happy to hear that so I called 611 and went through to the media net and was not offered the $19.99 deal but two other worthless options. Unlimited was nowhere to be found. I'm gonna call AT&T in the morning and ask if it is coming back and if not, why I got the text.
Anyone else get this? I know there are a few people here using GoPhone sims in iPhones.
