Fixing EE MMS on OnePlus
MMS cannot send over Wi-Fi alone. Go to Settings → Wi-Fi & network → SIM & network → Mobile data and enable mobile data even when you are connected to Wi-Fi.
Go to Settings → Wi-Fi & network → SIM & network → Access point names. Your EE APN entry must include: MMSC: http://mms/. Without the correct MMSC, picture messages cannot be sent or received.
While in APN settings, confirm the main APN field reads exactly: everywhere. An incorrect APN blocks MMS as well as regular data.
If the MMS fails for a specific image, check the file size. Most carriers including EE limit MMS to 1–3 MB. Reduce image size before sending.
Turn Wi-Fi off completely, then retry the MMS. Some devices route MMS through Wi-Fi incorrectly. With Wi-Fi off, the phone uses mobile data exclusively for MMS.
On Android: Settings → Apps → Messages → Storage → Clear Cache. Restart the app and retry. Cached errors can block MMS sending.
If MMS fails after all steps, call 150 (free from EE mobile). EE may need to resend your account provisioning, especially if your SIM was recently replaced.

| Cause | Likelihood | Fix |

Frequently Asked Questions
Why do MMS messages fail on EE?
MMS failure on EE is most commonly caused by mobile data being off, incorrect MMSC settings, or the message exceeding the carrier's size limit. Enable mobile data, verify MMSC: http://mms/, and reduce image size below 2 MB.
Can I send MMS over Wi-Fi on EE?
No — MMS requires mobile data even when Wi-Fi is available. This is a carrier infrastructure requirement that applies to EE and all UK networks. Enable mobile data and keep it on to send and receive picture messages.
What is the MMS size limit for EE?
Most UK carriers including EE limit MMS to 1–3 MB per message. If you are sending a photo larger than this, the message will fail silently. Reduce the image size before sending, or share via a data-based messaging app instead.
