How To Activate Iphone 11 Att

Got my iPhone 11 Pro Max in - Help me activate?

I got my brand new iphone in and took my sim card out of the old one and put it in my new phone but I have no cell service now. Where can I go to activate my phone online?

level 1

This is probably my biggest fail of all time. My new iPhone came with a sim... I put that sim back in my phone instead of swapping it. All is well now. Downvote me to oblivion. I can't believe I just did that ><

Don't worry we've all been there. I did that intentionally because I figured the new sim would activate when I turned the new phone on. (It worked when I did this in a Hotspot device) So in an attempt to prevent a trip to the store for a new sim I took the sim out of the new phone before I turned it on and put the old sim in it lol. It worked for a sec but likewise it said no service and wouldn't work until I put the new sim in. Naturally I had to make a trip to get a new sim for my old phone which I was adding service to. It's actually cool that Apple and AT&T can lock the phones down to a specific sim and make the phone prompt you for your carrier account info before it will activate.
