When your iPhone 17 Pro Max won't send pictures, it's usually a quick fix. The most common culprit is a simple network hiccup or a setting that needs a quick toggle. I'd start by checking your connection and then move through these steps.
Check Your Internet Connection First
Whether you're on WiFi or cellular, a weak connection will stop pictures from sending. Look at the top of your screen. If you see the WiFi icon, try loading a webpage to test it.
If the page won't load, go to Settings > Wi-Fi and toggle it off and back on. For cellular, ensure you have bars and that cellular data is enabled in Settings > Cellular.
Restart Your iPhone 17 Pro Max
A quick restart clears out temporary software glitches that can stall message sending. On your iPhone 17 Pro Max, press and quickly release the Volume Up button, then quickly press and release the Volume Down button.
Finally, press and hold the Side button until you see the Apple logo appear, then release. This force restarts the device without needing to fully power down.
Verify iMessage is Active and Working
If you're trying to send to another iPhone and the message bubble is green, iMessage isn't working. Head to Settings > Apps > Messages and make sure the iMessage toggle is on.
Sometimes, just turning iMessage off, waiting a few seconds, and turning it back on can re-establish the connection with Apple's servers and fix the sending issue.
Ensure MMS Messaging is Enabled
If you're sending a picture to an Android phone or a group chat, it uses MMS (Multimedia Messaging Service). This needs to be enabled in your settings. Go to Settings > Apps > Messages.
Scroll down and make sure MMS Messaging is turned on. Also, check that Send as SMS is enabled, which allows the picture to send as a regular text if iMessage fails.
Update Your Carrier Settings
Your carrier occasionally releases updates that improve network connectivity for messaging. To check, make sure your phone is connected to the internet, then go to Settings > General > About.
If a carrier settings update is available, a prompt will appear on this screen. Just follow the instructions to install it, which can often resolve sending problems.
Check Your Send & Receive Addresses
iMessage can get confused about which of your contact methods to use. Go to Settings > Apps > Messages > Send & Receive. Look under "You can be reached by iMessage at."
Make sure your current phone number is checked. If you have an old email address listed there that you no longer use, you can uncheck it to simplify the connection.
Disable Low Data Mode on Cellular or WiFi
Low Data Mode is designed to reduce data usage, but it can also prevent pictures from sending in the background. You need to check this setting for both your cellular and WiFi connections.
For cellular, go to Settings > Cellular > Cellular Data Options and turn Low Data Mode off. For WiFi, tap the "i" icon next to your network name in Settings > Wi-Fi and disable it there.
Force Quit and Reopen the Messages App
If the Messages app itself has a minor hang-up, closing it completely can help. On your iPhone 17 Pro Max, swipe up from the very bottom of the screen and pause in the middle to bring up the app switcher.
Find the Messages app card and swipe it up and off the top of the screen to close it. Then, tap the Messages icon on your Home Screen to reopen it and try sending the picture again.
Sign Out and Back Into Your Apple ID
This refreshes your account's connection to iMessage. Go to Settings > [Your Name] at the very top. Scroll all the way to the bottom and tap Sign Out.
You'll need your Apple ID password to turn off Find My. After signing out, restart your phone, then go back to Settings and sign in again. This can clear up account-related sending errors.
Reset Network Settings
If you've tried everything else, this is a strong next step. It clears all network configurations, including WiFi passwords, VPN settings, and cellular preferences. Go to Settings > General > Transfer or Reset iPhone.
Tap Reset, then choose Reset Network Settings. Enter your passcode when prompted and confirm. Your phone will restart, and you'll need to rejoin your WiFi networks, but it often fixes stubborn messaging issues.
