Setup guide
How to enter APN settings
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
No data on an unlocked or imported phone. Enter the APN by hand and restart. Set the APN to plus.acs.jp with username lm, password lm and CHAP authentication. Imported phones often skip LINEMO's automatic setup.
Saved the APN but still no data. After saving, you must select the LINEMO profile from the APN list. If it isn't selected, the connection won't come up.
Old carrier profile on iPhone. If a previous carrier's APN profile is installed, remove it — it can block LINEMO from connecting.
