Common issues
Data works but MMS won't send. Sky uses a separate MMS APN (mms.mobile.sky). If you only added the data profile, picture messages will fail while browsing works. Add the MMS values exactly and make sure mobile data is on. The MMSC ends .96 and the proxy ends .97, so entering one in both fields breaks picture messages.
No data on an unlocked or imported phone. Enter the APN mobile.sky by hand and restart. Unlocked phones often skip Sky's automatic setup, so the field starts empty.
Settings reset after an update. A software update occasionally clears the APN. Re-enter mobile.sky and the MMS values.
Frequently asked questions
Do I need to enter Sky Mobile APN settings by hand?
Sometimes. Sky Mobile runs on O2's network as an MVNO, and many phones pull the settings automatically, but a SIM swap, factory reset, or an unlocked phone often means entering the Sky Mobile APN by hand.
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 Sky Mobile support eSIM?
Yes. Sky Mobile supports eSIM on compatible phones. 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.
