What are iD Mobile 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 iD Mobile, 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.

How to configure MMS settings on Android (iD Mobile)

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

How to configure MMS settings on iPhone (iD Mobile)

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 iD Mobile 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 iD Mobile.

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 iD Mobile MMS problems

Sending problems with MMS usually trace to mobile data being off, or incorrect MMSC/proxy/APN type settings — check each.

MMS download issues: manual tap first, then check mobile data and any Auto-retrieve MMS option in the messaging app.

Compression on the sending device is the usual cause of blurry MMS — WhatsApp or iMessage often produce better results.

MMS on iD Mobile vs iMessage/WhatsApp

The 300KB-1MB MMS size limit brings heavy compression. iMessage, WhatsApp or Google Messages with RCS enabled send via data, avoiding MMS entirely.
