The APN is what lets a phone talk to Lyca Mobile's network for data, MMS and hotspot. Get it wrong and pages won't load.
Lyca Mobile's APN values for Android and iPhone follow, covering every field. When data shows connected yet nothing loads, start with the APN.
Comparing Lyca Mobile APN settings for different use cases

For Galaxy devices: Settings → Connections → Mobile Networks → Access Point Names. For Xiaomi/Redmi: 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.
Optimising your Lyca Mobile APN for 4G and 5G
For iOS 16 onward, look under Settings → Mobile Data → Mobile Data Network. If it isn't there, Lyca Mobile handles the APN automatically — Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings restores defaults.
Heads up: Lyca Mobile's carrier bundle can disable the APN field on newer iPhones, needing a support 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.
When to use Lyca Mobile internet APN vs MMS APN
Copy the values into the APN settings screen precisely; anything unlisted stays blank. Save, restart, then select it.
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 (Best Lyca APN Settings)
Data not working despite the correct Lyca Mobile APN? Try these in sequence:
1. Switch aeroplane mode on briefly then off, forcing reconnection to Lyca Mobile.
2. Restart the handset completely so the new APN takes effect.
3. Remove the APN entry and retype it fully; even one wrong character in the name or MMSC stops data working.
4. Wipe network settings entirely; Lyca Mobile's default APN is restored afterwards.
5. Look at the account side. Activation and remaining allowance can be checked through Lyca Mobile's hub.

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 (Best Lyca APN Settings)
MMS settings live in dedicated MMSC, proxy and port fields within the APN. Check these first if MMS won't work — a handful of Android phones need a separate entry.
