MMS is turned on in your phone's messaging settings, but the exact steps depend on whether you use an iPhone or Android device
MMS (Multimedia Messaging Service) lets you send photos, videos, and audio files through text messages instead of just plain text. Most phones have MMS turned on by default, but if you cannot send pictures or videos, you may need to enable it manually. The process takes less than a minute and lives in your phone's settings, not in the messaging app itself.
If you are having trouble sending media files, the problem is usually one of three things: MMS is disabled in settings, your carrier has not activated it on your account, or your phone does not have an active data connection. This guide covers how to turn MMS on. If you turn it on and still cannot send pictures, contact your carrier to confirm MMS is active on your plan.
Key Takeaways
- On iPhone, go to Settings > Messages and toggle on MMS Messaging; on Android, the setting is usually in Messages > Settings > Advanced or Multimedia Messages.
- MMS requires an active data connection (cellular data or Wi-Fi) to send and receive picture and video messages.
- If MMS is already on but you still cannot send pictures, your carrier may not have activated MMS on your account, which requires a separate call to customer service.
- Some carriers charge per MMS message or include them in your plan; check your carrier's pricing before sending to large groups.
How to enable MMS on iPhone
Open Settings and tap Messages. Scroll down until you see MMS Messaging and toggle it on. The switch will turn green when it is active. If you do not see this option, your phone is running an older version of iOS — update to the latest version first by going to Settings > General > Software Update.
After you turn MMS on, wait a few seconds for your phone to connect to your carrier's network. You should then be able to send photos, videos, and audio files through the Messages app. If the toggle is already on and you still cannot send pictures, restart your phone and check that you have an active data connection.
How to enable MMS on Android
The exact location varies by phone brand and Android version, but the process is similar across most devices. Open your default messaging app (usually called Messages, SMS, or the app your carrier provides). Look for a menu icon (three dots or lines) and tap Settings or Advanced Settings. From there, find Multimedia Messages or MMS and toggle it on.
If you cannot find the setting in your messaging app, try opening Settings > Apps > Messages (or your carrier's messaging app) > Permissions and make sure the app has permission to access your phone's storage and data. Some Android phones also require you to set a default messaging app before MMS will work. Go to Settings > Apps > Default Apps and choose your messaging app as the default SMS/MMS handler.
What to do if MMS is on but pictures still will not send
Check that you have an active data connection. MMS messages travel over your cellular data or Wi-Fi network, not through regular text message channels. If you are on Wi-Fi, make sure the connection is stable. If you are using cellular data, check that data is turned on in your phone's settings and that you have not hit your data limit.
If your data connection is working but pictures still will not send, contact your carrier. MMS must be activated on your account separately from your phone plan, and some carriers require you to request it or add it as a feature. Call your carrier's customer service line (the number is usually on your bill or the carrier's website) and ask them to confirm MMS is turned on for your account. They can usually activate it over the phone in a few minutes.
MMS and group messages
When you send a message with a picture or video to multiple people, your phone automatically converts it to an MMS message. Some carriers charge per MMS message, so sending one picture to ten people may count as ten separate messages on your bill. Check your carrier's pricing plan to understand whether MMS messages are included or charged separately.
If you want to send photos to a group without using MMS, consider using a messaging app like WhatsApp, Facebook Messenger, or iMessage (on iPhone). These apps send pictures over data or Wi-Fi instead of through your carrier, so they do not count against MMS limits or charges.
Why MMS might be turned off by default
Some phones ship with MMS disabled to prevent accidental charges on plans that meter MMS messages. Older phones or phones sold in certain regions may also have MMS off to comply with carrier requirements. If you bought your phone used or refurbished, a previous owner may have disabled it.
Turning MMS back on in settings will not cause any charges — your carrier determines pricing based on your plan, not whether the feature is enabled. Once you enable it, you can send and receive multimedia messages the same way you would send a regular text.
Frequently Asked Questions
Does MMS use data or text messages?
MMS uses your data connection (cellular data or Wi-Fi), not your text message allowance. If you have unlimited texting but limited data, sending many MMS messages can affect your data usage. Check your plan to see whether MMS counts against your data limit.
Can I send MMS over Wi-Fi only?
Yes. If you have Wi-Fi turned on and MMS enabled, you can send and receive picture messages over Wi-Fi without using cellular data. This works on both iPhone and Android, though some carriers may require a data connection for MMS to work properly.
What file types can I send with MMS?
Most carriers support JPEG and PNG images, MP4 and 3GP video files, and MP3 audio. Very large files may be compressed automatically by your phone or carrier. If a file is too large, your phone will usually show an error message and suggest reducing the file size.
Why do my MMS messages say "pending" or fail to send?
This usually means your phone does not have a stable data connection. Move to an area with stronger signal, switch to Wi-Fi, or restart your phone. If messages still fail after restarting, contact your carrier to confirm MMS is active on your account and that your data connection is working.
