Common issues
Picture messages won't send. Optus uses a second APN for MMS. Add mms with APN type mms only, the MMSC http://mmsc.optus.com.au:8002 and the MMS proxy 61.88.190.10 on port 8070. Putting default in the MMS APN's type can block MMS.
MMS still fails with the right values. Ask Optus support to turn MMS off and on for your account.
An old phone has no service. Optus shut down 3G on October 28, 2024. A phone without 4G calling can't connect, whatever the APN.
Frequently asked questions
Do I need to enter Optus APN settings by hand?
Usually not. Optus owns its network, and most phones pull the settings automatically. You enter them manually when data or MMS stops working, often after a SIM swap, a factory reset, or moving the SIM into an unlocked phone.
How do I know it worked?
Turn off Wi-Fi and open any website. If it loads, data is working. For MMS, send a photo to a friend and confirm it goes through. A quick restart helps if either doesn't start right away.
Does Optus support eSIM?
Yes. Optus supports eSIM. Activation usually sets up the data settings automatically, so you rarely touch the APN on an eSIM line.
Why won't my iPhone let me edit the APN?
Many carriers manage the iPhone APN through a hidden configuration profile, so the fields are locked or missing. That's normal. Resetting network settings re-pulls the profile and fixes most iPhone issues without manual entry.
These settings didn't fix it. What now?
Restart the phone first. If data still won't connect, reset network settings and let the carrier re-provision. If only MMS fails, re-check the MMSC and make sure mobile data is on. APN settings can't fix a deactivated line, an unpaid balance, or a locked phone.
