Set up O2 picture messaging on Android and iPhone. O2 uses MMSC http://mmsc.mms.o2.co.uk:8002 with MMS proxy 82.132.254.1 on port 8080 — different from EE, so double-check each value.

Common MMS mistakes that stop picture messages working

What are O2 MMS settings?
MMS (Multimedia Messaging Service) lets you send picture messages, video clips and audio files as text messages. To send and receive MMS on O2, your phone needs the correct MMSC address, MMS proxy and MMS port values configured in the APN settings. Without these, picture messages may fail to send, download or appear as empty boxes.
Enter MMS fields exactly as shown — the MMSC must start with http:// not https://

How to configure MMS settings on iPhone
On iPhone, MMS settings are part of the mobile data network settings at Settings → Mobile Data → Mobile Data Network. Scroll down to the MMS section and enter the O2 MMSC, MMS Proxy and MMS Max Message Size values. Tap the back arrow to save.
If the MMS section is missing on iPhone, go to Settings → Messages and make sure MMS Messaging is toggled on. If it remains greyed out, your iPhone carrier bundle may need updating — contact O2.

Fastest way to apply new APN settings
After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.
Troubleshooting O2 MMS problems
Picture messages not sending: Check that mobile data is turned on (MMS requires mobile data even on Wi-Fi). Verify the MMSC address and MMS proxy are correctly entered. Make sure the APN type includes mms.
Picture messages not downloading: Tap the message to manually trigger a download. Check your mobile data is enabled. Some messaging apps require you to enable Auto-retrieve MMS in their settings.
MMS working but blurry: This is usually an issue with the sending device compressing the image. Ask the sender to use a different messaging app. WhatsApp or iMessage may give better quality for image sharing.

Follow these steps in order — most issues are resolved by step 1 or 2
MMS on O2 vs iMessage/WhatsApp
Standard MMS is limited in file size (usually 300KB to 1MB) and compresses images heavily. For high-quality photo and video sharing, use iMessage (iPhone to iPhone), WhatsApp, or Google Messages with RCS enabled. These apps send over internet data and do not use MMS compression.
O2 MMS messages may fail to send if the MMS APN settings are missing or incorrect. Check the MMSC, MMS Proxy and Port values in your settings match the O2 values shown above.
Do I need mobile data to send MMS on O2?
Yes, MMS picture messages require mobile data to send and receive, even if you are connected to WiFi. Make sure mobile data is enabled when sending MMS on O2.
What is the O2 MMSC address?
The O2 MMSC address is listed in the APN settings table above. Enter it exactly as shown, including the http:// prefix and port number if required.
Why are MMS settings greyed out on my phone?
MMS settings may be greyed out because your carrier has locked the APN settings. Contact O2 to request an APN unlock, or try inserting the SIM into another compatible device.
Can I receive MMS without setting up the APN on O2?
On most modern phones, O2 MMS settings are configured automatically. If MMS is not working, manually enter the MMSC, Proxy and Port values from the table above.
