Have you seen a triangle with an exclamation point on your iPhone? This symbol is a warning sign. It means something on your phone needs to be fixed. Apple uses this all over iOS to indicate that something is either wrong or needs your attention. Most commonly, people are confused by it when it shows up as an icon in the upper right-hand corner of your phone. Let’s talk about what this symbol is and what you can do about it.
Basic Troubleshooting Steps
Before diving into more complex solutions, let’s start with some basic things you’re able to do:
When You Might See This Symbol
This triangle warning usually shows up when there’s a problem with your phone’s connection or something isn’t working right. Here are some common reasons you might see it:
Why Does This Symbol Show Up?
The triangle with an exclamation mark is an alert from your iPhone. It’s telling you that something needs to be checked. This could be a small issue or something more serious. Knowing when this symbol shows up can help you figure out what’s wrong.
What Could Be Causing the Problem
Figuring out why this symbol is showing up can be tricky. Here are some things that might be causing it:
Different Places You Can See It
Upper Right Hand Corner
If you’re seeing the icon in the upper right hand side of your iPhone (usually next to the Wifi icon) and aren’t getting any cellular service, it could be a carrier network issue. It’s recommended you restore your phone to a previous update, roll back any iOS updates, and/or factory reset your phone to see if the issue resolves.
If the icon doesn’t disappear after a full reset and restore from backup then there is a failure in one or more critical hardware components (internal storage, cellular radio/baseband, CPU, display, etc.) requiring repair/replacement on the iPhone. Take your phone into a repair shop and they should be able to diagnose the specific issue for you and get you more information on that.

During Facetime
If you are in or trying to start a Facetime conversation and a Triangle with Exclamation Mark shows up on your screen, that indicates that you have a poor network connection between you and the other person. The issue can be on your side or the person you are talking to (or both) and can sometimes resolve on its own if network conditions improve. Once thing you can try is to switch from cellular data over to WiFi to see if that fixes it. Otherwise you will have to wait until your network / internet connection improves before trying again.
Icon Followed By An Error or Warning
Apple / iOS commonly use the symbol to draw your attention to an error on your phone. Sometimes you’ll see it when your phone is unable to be activated above the ‘Unable To Activate’ warning. In this case, read the warning below the icon to find out what it is specifically referring to and act to resolve the error.
Emergency Alerts
Sometimes you will see a yellow triangle with a black exclamation mark in it pop up next to a message labeled ‘Emergency Alerts’. This is normal behavior for emergency alerts that are sent from the carriers through the Emergency Alert System. The icon is there to draw your attention to the message, but isn’t an error or anything out of the ordinary.
