Your data plan does not work on this device

    I have an iPhone 6s plus, and just about an hour ago, when I try to go on the internet, using data, it goes to a Tmobile page that says "your data plan does not work on this device. I didn't switch phones, cards, plans, or anything. I am on my daughter's plan, and we didn't change anything, and we have unlimited data. I thought maybe it was because I had not done the update, so did the update, and afterwards, did a reset, and still no data. What is wrong?
