iMessage network question

[jackryan57]

Hi everyone,

I have my daughter's ATT phone set to shut off internet, texts and phone at 10 pm. I did this through the ATT site. I also have my wifi router set up to shut down all traffic at 10 pm.

Last night she was texting after 10 and she told me that for some reason she can send iMessage texts to another iPhone user.

How is this possible with everything shut down?

Thanks

Have a neighbor that has an open WiFi network she might be jumping on?
