APN stands for Access Point Name, the configuration needed to reach Lyca Mobile for internet, MMS and tethering.
These are Lyca Mobile's suggested APN settings across both platforms. If data connects but pages won't load, check the APN first.
Entering Lyca Mobile APN values on Samsung
Android's APN screen sits at Settings → Network & Internet → Mobile Network → Access Point Names on most phones (Connections on Samsung).
Samsung keeps this at Settings → Connections → Mobile Networks → Access Point Names; on Xiaomi and Redmi it's Settings → SIM cards & Mobile Networks → Access Point Names.

Saving an APN does not activate it — you must select it
On Android, after tapping Save the new APN appears in the list but is not yet active. Tap the radio button (empty circle) next to it so it becomes filled. The profile is only active when the circle is filled. Then toggle aeroplane mode or restart.
Samsung APN field locked or greyed out (Lyca APN Settings Samsung)
With iOS 16 or later, check Settings → Mobile Data → Mobile Data Network. No option there usually means Lyca Mobile auto-configures it; a network reset restores the defaults.
Certain new iPhones grey out the APN entirely under Lyca Mobile's bundle — support must push an update.

APN field greyed out? Here is why
On Android: the field is locked by a carrier profile. Go to Settings → Network & Internet → Mobile Network → Access Point Names and tap Reset to Default (three-dot menu). On iPhone: the carrier bundle controls the APN — it cannot be edited manually. Contact your network to push an updated carrier profile, or insert the SIM in another phone to test.

APN values are case-sensitive — enter them exactly
Type every character exactly as shown — no spaces before or after, no capital letters unless listed. One wrong character stops mobile data from working. After saving on Android, tap the radio button (filled circle) next to the new profile to activate it.
Testing your Lyca Mobile connection after saving APN (Lyca APN Settings Samsung)
Populate the APN screen using the values shown, ignoring anything absent. Save, restart, then choose the profile.
After saving your APN settings, always restart your phone and test a website before making further changes. If you have multiple APN profiles, make sure the correct one is selected (shown with a filled circle on Android).

Fastest way to apply new APN settings
After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.
Troubleshooting Lyca Mobile APN issues (Lyca APN Settings Samsung)
If Lyca Mobile's APN values haven't fixed it, run through the following:
1. Start with an aeroplane mode toggle, which re-registers the APN on Lyca Mobile's network.
2. Give the phone a full restart to clear glitches and apply the values.
3. Start the APN fresh — delete it and re-enter every value carefully, since a typo in the name or MMSC is a common culprit.
4. A complete network settings reset clears Wi-Fi and Bluetooth pairings but brings Lyca Mobile's defaults back.
5. Check for an account issue: SIM activation, account status and remaining allowance.

Common MMS mistakes that stop picture messages working
• The MMSC URL must begin with http:// — never https://
• The MMS Proxy field is an IP address only — no http:// prefix
• APN Type must contain mms (e.g. default,supl,mms)
• On Android, save then select the profile before testing
APN settings for MMS on Lyca Mobile (Lyca APN Settings Samsung)
Separate MMSC, MMS proxy and MMS port fields handle picture messaging within the APN. These are worth checking first; some Android phones need their own MMS APN.
