So today I've been getting a LOT of weird popups on my phone. It will not connect to the data network and anytime I do anything (even not involving data) I get this popup.

I'm pretty sure it's because I'm at the end of my data cycle and I have yet to pay, but they sent me an email three days ago saying in SIX days they would cut my account, and I plan to pay tomorrow. Why would they lie about that?
Anyone else seeing this error? I've searched and some results say its a "4G network update" but that's only part of the code.
Whenever I search the full code I get jumbled answers not including mine.
