The APN is what lets a phone talk to SMARTY's network for data, MMS and hotspot. Get it wrong and pages won't load.
These are SMARTY's suggested APN settings across both platforms. If data connects but pages won't load, check the APN first.
Comparing SMARTY APN settings for different use cases
Android 10+ route: Settings, Network & Internet (Connections on Samsung), Mobile Network, Access Point Names.
Samsung Galaxy keeps Smarty's APN at Settings → Connections → Mobile Networks → Access Point Names, while Xiaomi and Redmi differ.

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 SMARTY APN for 4G and 5G
For iOS 16 onward, look under Settings → Mobile Data → Mobile Data Network. Its absence means SMARTY handles the APN automatically.
Heads up: SMARTY's carrier bundle can disable the APN field on newer iPhones.

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 SMARTY internet APN vs MMS APN
These Smarty values go into the APN settings screen exactly as listed. Save, restart and 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 SMARTY APN issues
If SMARTY's APN values haven't fixed it, run through the following:
1. Switch aeroplane mode on briefly then off, forcing reconnection to SMARTY.
2. Power the device down and back up to clear temporary faults.
3. Delete and recreate the profile — one typo is a common cause of failure.
4. Wipe network settings entirely; SMARTY's default APN is restored afterwards.
5. Look at the account side. Activation and remaining allowance can be checked through SMARTY'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 SMARTY
The APN profile's MMS fields (MMSC, proxy, port) are distinct from the main internet settings — check these first, since some Android phones need a dedicated MMS APN.
