I am very careful in my data usage, but for the last few months, I've nearly gone over due to "DNS" services. I don't allow background app refresh and have turned off cellular data for all my apps, but the DNS issue won't go away. I've also cleared all my browser history, turned my iPhone off and back on again (for all the IT nerds), and nothing has helped. This spontaneously started happening and I can't seem to figure it out. Any suggestions would be appreciated. I am on an iPhoneSE and have all the latest updates.

Tried searching a bit, some of these seem fairly old (iOS 10 issues) but might be helpful?
