Access Point Name (APN) tells the handset how to reach iD Mobile for internet, picture messaging and tethering.
iD Mobile's APN values for Android and iPhone follow, covering every field. When data shows connected yet nothing loads, start with the APN.
Entering iD Mobile APN values on Samsung
Recent Android builds keep it under Settings → Network & Internet → Mobile Network → Access Point Names, or Connections on Samsung. Use plus to create, tap to edit.
On Samsung it's Settings → Connections → Mobile Networks → Access Point Names; Xiaomi/Redmi route via 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.
APN settings greyed out on Samsung (iD Mobile)
iOS 16 and up keeps it at Settings → Mobile Data → Mobile Data Network. Missing? iD Mobile configures the APN itself; a network reset restores defaults.
On some recent iPhones, iD Mobile's bundle locks APN editing; only a iD Mobile-side update will change it.

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 iD Mobile connection after saving APN
Fill the APN screen with the iD Mobile values below and skip anything absent. Save, reboot, then activate 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 iD Mobile APN issues (Samsung)
Data not working despite the correct iD Mobile APN? Try these in sequence:
1. Cycle aeroplane mode for ten seconds so the phone rejoins iD Mobile and reloads the APN.
2. Do a full power cycle to flush glitches and activate the new APN.
3. Wipe and re-enter the APN, since a stray character in iD Mobile's APN name or MMSC stops data.
4. Do a full network reset — both platforms restore iD Mobile's defaults at the cost of saved pairings.
5. Rule out an account issue: SIM activated, account active, allowance intact? iD Mobile's hub or support can confirm.

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 iD Mobile (Samsung)
MMS on iD Mobile depends on its own APN fields. When sending or downloading breaks, start there.
