Fix iPhone Cellular Data Problems by Resetting Network Settings
I love my iPhone but it’s had a share of networking quirks, and one of them is the seemingly random inability to access the cellular data network. I don’t know if this is an AT&T problem or an iPhone problem, but it’s really annoying to not be able to use 3G/4G / LTE service when I need to. I went looking for a solution for the problem and came across a pretty simple and straightforward fix after digging around for a while, and it’s extremely easy to do. What you’ll want to do to resolve your cellular or general network data problems is reset the iPhone Network Settings, which we’ll show you how to do.
This only takes a few seconds and can be done on any iOS device the same way, though our focus here is for the iPhone since it’s cellular capabilities are essential to the hardware functioning properly.
How to Reset Network Settings on the iPhone
This applies to iOS in general with all cell capable iPhones, regardless of carrier. That means whether it’s from Verizon, T-Mobile, Sprint, AT&T, or whoever else, it’s worth a shot when troubleshooting network difficulties, and it may even fix wi-fi problems too:
- Open Settings then go to “General” followed by “Reset”
- Tap on “Reset Network Settings” and confirm the reset by tapping the giant red button
Most cellular data and networking issues with the iPhone (or 3G/LTE iPads) will now be resolved. Though it’s not necessary, rebooting the iPhone can be helpful in some cases. You can do that just by turning it on and off again through the power button.
This process has the side effect of ditching all passwords to wireless routers and access points, meaning you will have to reenter them when you find those networks again. You may want to make note of any particular crazy wifi keys before doing this.
Prior versions of iOS had the same functionality, it just looked slightly differently:
Anyway, this solution worked for me and anytime there are persistent network issues it seems to resolve them. If you’re having problems with your iPhone cellular data connection or any networking oddities, try resetting the network settings yourself, it might just work.
