Auto-provisioning
Many phones on 48 receive APN settings automatically when a SIM is inserted. Only enter these manually if your device shows no data connection or was purchased unlocked.
Setup guide

How to enter APN settings

  1. Open Access Point Names

    Go to Settings → Network & Internet → Mobile network → Access Point Names. On some phones it's under Settings → Connections → Mobile networks.

  2. Add a new APN

    Tap + (or the menu → New APN) and set APN to 48months.liffeytelecom.com. Fill any other non-blank values from the table above and leave the rest as default.

  3. Save and select it

    Save from the menu, then select the new 48 APN and toggle Airplane Mode on for ten seconds so the change takes effect.

  1. Open the APN screen

    Tap Settings → Mobile Service → Mobile Data Network. On some iPhones the menu is called Mobile Data. If you don't see this option, 48 locks APN editing, so contact them or install a carrier profile.

  2. Enter the APN

    Under Mobile Data, set APN to 48months.liffeytelecom.com. Leave Username and Password blank unless the table above lists them.

  3. Save and restart data

    Go back to apply the change, then toggle Airplane Mode on for ten seconds so the iPhone re-registers with 48.

Tip
After saving, toggle Airplane Mode on and off for 10 seconds. This forces the phone to re-register with the network and pick up the new APN.
Troubleshooting

Common issues

The new APN won't save. On many Android phones the APN only saves from the menu, or when you back out of the edit screen. Open the list again and check it's there and selected.

Data works but MMS doesn't. Check whether your phone uses one APN or two. On Android, open Access Point Names. One entry covering internet and MMS needs the type default,supl,mms. If you see separate entries, put the MMS values on the MMS one.

No data abroad. Roaming data needs Data Roaming on and the network chosen by hand.

FAQ

Frequently asked questions

Does 48 need a username?

Some setups use the username user, others leave it blank. Start with it blank. If data won't connect, enter user and set authentication to PAP.

Why does the MMSC look incomplete?

http://mmc1/servlets/mms is a short internal address that only works inside the network. It's correct as written. Copy it exactly, with no .ie or .com added.

Can I use Three's APN on a 48 SIM?

No. 3ireland.ie is for Three's own SIMs. A 48 SIM needs 48months.liffeytelecom.com, even though both run on Three's masts.

Does 48 support eSIM?

No. 48 is sold as a physical SIM only.

Why won't my iPhone let me edit the APN?

Some carriers manage the iPhone APN through a hidden carrier profile, so the fields are locked or missing. That's normal. Resetting network settings re-pulls the profile and fixes most iPhone data problems without typing anything.
