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.

Setting up MMS on Android (O2 MMS Settings)
Go to Settings → Connections → Mobile Networks → Access Point Names. Tap your existing O2 APN or create a new one. Fill in the MMSC field, the MMS Proxy field, and the MMS Port field with the O2 values. Make sure the APN Type field includes mms (for example: default,supl,mms). Save and restart.

Setting up MMS on iPhone (O2 MMS Settings)
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.

O2's MMSC address must stay on http:// rather than https://
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.
Troubleshooting checklist
Most O2 cases resolve within the opening couple of steps
MMS on O2 vs iMessage/WhatsApp
O2's standard MMS tops out around 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.
