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 ereseller. 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 Lycamobile APN and toggle Airplane Mode on for ten seconds so the change takes effect.

  1. Open the APN screen

    Tap Settings → Cellular → Cellular Data Network. If you don't see this option, Lycamobile locks APN editing, so contact them or install a carrier profile.

  2. Enter the APN

    Under Cellular Data, set APN to ereseller. 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 Lycamobile.

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

data.lycamobile.com no longer connects. Lycamobile now recommends ereseller, with AT&T's MMS values. Add it as a new APN, select it and restart.

Username and password. On Android, leave both blank. On an iPhone with iOS 26.4, use lmus and plus with data.lycamobile.com. Try blank first, then lmus and plus if data still fails.

An iPhone won't show the APN fields. iOS 17 and later set the APN up on their own. Fields only need typing after a reset or a major update.

FAQ

Frequently asked questions

Should I use ereseller or data.lycamobile.com?

Lycamobile recommends ereseller, with the MMSC http://mmsc.mobile.att.net and MMS proxy proxy.mobile.att.net. Its second setup is data.lycamobile.com with the MMSC http://lyca.mmsmvno.com/mms/wapenc, for SIMs on T-Mobile. If one doesn't connect, try the other, and restart after each change.

Do I need to enter Lycamobile APN settings by hand?

Usually not. Lycamobile runs on AT&T, and on T-Mobile for older SIMs,, 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 Lycamobile support eSIM?

Yes. Lycamobile 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.
