What Are the Network Settings on Iphoneの概要と注目ポイントを一挙に解説しました。

Now we’re getting into the deep end. Under Settings > General > VPN & Device Management, you can configure a VPN. This is for people who think their ISP is reading their texts. Or for accessing region-locked Netflix. But here’s the kicker: if you install a VPN app, you’ll see a little “VPN” icon in your status bar. Very cool, very mysterious. But if you ever see that icon and you didn’t set it up? Panic. Your data might be getting rerouted through a random server in Belarus. Yeah, that’s happened to people.

How to fix Wi-Fi not working on iPhone, iPad

And DNS—sounds like a disease, right? It stands for Domain Name System. In Settings > Wi-Fi > (i) > Configure DNS, you can change it from Automatic to Manual. Why would you? Because default DNS from your ISP can be slow. Switch to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google), and websites load faster. It’s like giving your internet a Red Bull. But only do this if you like tinkering. Otherwise, leave it alone.

Cellular Data: The Wallet Unfriendly Section

Let’s be honest: Cellular Data is where Apple makes you pay for your sins. Go to Settings > Cellular, and you’ll see a list of every app that’s slurping your data. Scroll down. See that Google Maps using 2.3GB? Yeah, that’s why you got a “Data Limit Reached” text. Turn off the toggles for apps you don’t need on cellular. Instagram? Keep it. Spotify? Maybe download your playlists instead.

And look for “Wi-Fi Calling.” If your carrier supports it, toggle it on. This lets you make calls over Wi-Fi when your signal is a single bar. Perfect for basements or that one spot in your kitchen where calls always drop. Just be aware: some carriers count Wi-Fi calls against your minutes. Because of course they do.
